Weather in Lima, Peru by Month
Weather in Lima, Peru by Month
Lima doesn’t follow the tropical playbook. There’s no monsoon season, no sweltering summer heat, and no dramatic temperature swings year round. What you get instead is a city shaped by coastal desert conditions along the Pacific Ocean—mild, gray, and surprisingly humid for much of the year. If you’re wondering about the climate in Lima and how it varies month by month, the short answer is: less than you’d expect, but enough to matter.
The biggest factor isn’t rain—it’s cloud cover. Lima sits in a fog belt created by the cold Humboldt Current offshore, which keeps temperatures moderate but skies overcast from May through November. December to April brings the relative “summer,” with more sun and slightly warmer days. Wherever you stay, the weather will shape your experience—check out this guide on where to stay in Lima to pair the right neighborhood with the right season.
Understanding Lima's Climate: What the Weather Is Like Throughout the Year
Lima’s climate in its simplest form: arid coastal desert, moderated by the Pacific Ocean and split into two broad thermal zones. December to March is summer—pleasantly warm, sunnier, and the best window for outdoor activity. June to September is winter—cool, overcast, and blanketed in mist. The transition months either side are shoulder seasons worth considering.
What makes Peru weather unusual is what doesn’t happen. Lima almost never rains. The average annual precipitation accumulation is just 8–10mm—drier than the Sahara. What you get instead is the garúa, a coastal mist that hangs over the city, particularly from June to October.
Understanding this distinction—mist vs. rain—is the key to reading Lima’s climate data accurately.
Monthly Temperatures in Lima: Average High and Low
January – February (Peak Summer)
January and February deliver Lima’s warmest weather. The average high temperature sits at 26–27°C (79–81°F), and average daily sunshine peaks for the year. Skies clear more reliably, and the city feels vibrant and genuinely alive. Sunset comes around 6:30pm, leaving long, warm evenings for outdoor dining along the Malecón.
This is also when domestic tourism peaks. Peruvians from other regions flock to Lima’s beaches, so coastal areas and popular restaurants fill up on weekends.
Best for: Beachgoers, first-time visitors who want sun, anyone combining Lima with a highland trip before the Andean rainy season intensifies.
March – April (Late Summer / Shoulder)
March retains most of January’s warmth but crowds thin noticeably. By April, the garúa—Lima’s signature coastal mist—begins creeping back. Average temperatures drop a few degrees, and mornings can feel noticeably cooler than just weeks prior.
April is a sweet spot for travelers wanting reasonable weather without peak-season prices. Holy Week (Semana Santa) in late March or April is the major exception—expect full hotels and busy streets across the city.
Best for: Budget-conscious travelers, couples, anyone who prefers fewer crowds with still-manageable weather.
May – August (Lima Winter)
This is Lima’s gray season. The garúa blankets the city in low cloud and mist almost daily. Temperatures are mild—average high temperatures in the high teens to low 20s°C—but the dampness makes things feel colder than the numbers suggest. On still days when moisture hangs close to the coast, it can feel genuinely muggy despite the cool air.
July is the busiest month, driven by Fiestas Patrias (July 28–29) and a surge in international tourists heading to Machu Picchu during the Andes dry season. Prices spike and accommodation books out early.
Best for: Culture-focused travelers, budget travelers (outside July), anyone prioritizing the highlands over Lima’s beaches. Avoid if: You need sun for your mental health, or are traveling with young children who need outdoor time.
September – November (Spring Shoulder)
The garúa slowly retreats. September is still mostly overcast, but by October and November, blue skies return with increasing regularity. Monthly temperatures climb back toward the low-to-mid 20s°C. Sunrise arrives earlier and evenings stay brighter later into the month.
Crowds are manageable and prices haven’t yet spiked to summer levels. November is increasingly recognized by experienced travelers as one of Lima’s most underrated months.
Best for: Experienced travelers, photographers, anyone who wants improving weather without January’s crowds.
December (Early Summer)
December marks the return of Lima’s summer, though the transition isn’t always clean. Early December can still see overcast days, with reliable sun arriving more consistently from mid-month onward. Christmas and New Year’s push tourist numbers up sharply toward month’s end.
Best for: Holiday travelers, those combining Lima with Cusco before Andean rains intensify from January to April.
Average Temperature in Lima: Highs, Lows, and What They Feel Like
Lima’s average temperature is remarkably stable compared to most major cities. The average high temperature in summer (January–March) reaches 26–27°C (79–81°F), while winter overnight average low temperature dips to around 14°C (57°F). The annual swing is only about 9°C—narrow by global standards.
Summer feels warm but rarely oppressive. The Pacific Ocean breeze keeps afternoons comfortable even in January. In winter, the garúa makes 18°C feel closer to 12°C due to the ambient damp. Pack a layer regardless of season—evenings cool quickly year round.
UV exposure is a consistent risk. Even in winter, Lima’s UV index rarely drops below 8. In summer it peaks at 14–16—among the highest in South America. Sunscreen is essential every day, regardless of cloud cover. In summer months, the UV index can burn unprotected skin in under 20 minutes—even through a thin thermal layer of haze.
Precipitation in Lima: Why It Almost Never Rains
Lima is one of the driest major capitals on Earth. Annual precipitation accumulation averages just 8–10mm—less than Cairo receives in a single storm. In practical terms, Lima almost never rains in any meaningful sense.
What visitors experience instead is the garúa: fine coastal mist with negligible accumulation. It settles over the city from around May to November, particularly in Miraflores and Barranco. It won’t soak you, but it makes surfaces slick and outdoor photography frustrating.
Umbrellas are rarely necessary. The primary concern from precipitation isn’t disrupted plans—it’s the ambient damp making mornings feel raw and cold.
For official precipitation data by weather station, see SENAMHI’s Lima climate records.
Humidity in Lima: High, Muggy, and Persistent
Relative humidity averages 80–85% throughout the year—high by any standard. In summer (December to March), the warmth offsets this somewhat, and the combination feels mild and coastal rather than oppressive. Think pleasantly warm sea breeze, not sticky jungle heat.
In winter (June to September), high humidity combined with low temperatures and persistent cloud cover creates what locals call fría de Lima—Lima’s cold. It’s not deep cold, but the damp penetrates in a way that surprises travelers from dry climates. On the worst days, the air along the coast feels genuinely muggy despite temperatures in the mid-teens.
Anyone with respiratory sensitivities should prepare accordingly, particularly in July and August.
Is Lima Busy? Tourism Levels by Month
Peak months: January, February, July, December Shoulder months: March, April, November Low season: May, June, August, September, October
July is the single busiest month—Fiestas Patrias (July 28–29) drives both domestic and international demand simultaneously. Flights and hotels, especially in Miraflores, book out weeks in advance. Prices in 2026 are expected to rise 20–40% above shoulder month rates around the holiday.
January and February see strong beach tourism from domestic visitors. December’s last two weeks spike sharply around Christmas and New Year’s.
School holidays in Peru (January–March and July) amplify crowd levels at popular sites like Larco Mar, Huaca Pucllana, and the historic center.
Best Things to Do in Lima by Season
Summer (December–March) — Sunshine & Outdoors
- Walk the Malecón clifftop promenade in Miraflores—best at sunrise for calm conditions before crowds arrive
- Visit Huaca Pucllana at sunset—warm evenings make outdoor dining at the on-site restaurant ideal
- Spend a morning at Playa La Herradura or Playa Agua Dulce along the coast
- Explore Barranco’s vibrant streets and street art on foot in good weather
- Take a day trip to Pachacamac archaeological site (exposed ruins need sun to do them justice)
- Paraglide off the Miraflores cliffs over the Pacific Ocean (clearest views and best sunshine hours in summer)
Winter (May–August) — Culture & Indoors
- Visit the Larco Museum—world-class pre-Columbian collection, entirely indoors
- Spend a half-day at MALI (Museo de Arte de Lima)
- Eat your way through the Central Market and nearby cevicherías (Lima’s food scene is weather-proof)
- Take a Lima food tour—winter is peak season for culinary tourism
- Visit the catacombs beneath the Basílica de San Francisco in the historic center
- Catch a live performance at the Gran Teatro Nacional
Weather by Month in Cities Near Lima: Quick Comparison
Lima’s climate is one of the most distinct of any major Peruvian city. Here’s how it compares to destinations near Lima and further afield:
- Cusco: Sits at 3,400m in the Andes. Much colder, with a genuine rainy season (November–March) and cold, clear dry winters. Altitude is a serious factor when you visit Peru’s highland cities.
- Arequipa: Drier and sunnier than Lima year round, with warm days and cooler nights. Peru weather in Arequipa is often more predictable and sunnier than Lima.
- Iquitos: In the Amazon basin—hot, humid, and genuinely tropical. Rainfall is heavy and year-round. A completely different climate zone from Lima’s arid coast.
If you’re planning a multi-city Peru trip in 2026, Lima’s coastal weather averages will feel markedly different from both highland and jungle destinations.
Sea Temperature Near Lima
The Pacific Ocean near Lima is cold year round—a direct effect of the Humboldt Current. Sea temperature typically ranges between 16–19°C (61–66°F), even in summer. This keeps the city’s air temperatures moderate and drives the garúa mist, but it also means Lima’s beaches aren’t the warm-water swimming destinations you might expect. Most locals swim in summer (January–March) when air temperatures make it more bearable despite the cool water.
Sunshine Hours and Daylight in Lima
Lima receives an average daily sunshine of 4–6 hours in summer (December–March) and as little as 1–2 hours in the depths of winter (June–August), when cloud cover is near-total for weeks at a time.
Sunrise in Lima falls between 5:50am (December–January) and 6:30am (June–July). Sunset ranges from around 6:10pm in winter to 6:40pm in peak summer. Days are fairly consistent in length year round, given Lima’s proximity to the equator—but the quality of those daylight hours varies enormously between seasons. A graph of Lima’s sunshine hours would show a dramatic dip from May to August, with a sharp recovery through October.
Events & Festivals in Lima
| Month | Event |
|---|---|
| January | Summer concerts and beach festivals in Costa Verde |
| February | Carnival celebrations (low-key in Lima vs. other Peruvian cities) |
| March/April | Semana Santa (Holy Week)—city-wide, major domestic travel |
| July 28–29 | Fiestas Patrias (Independence Day)—parades, fireworks, full hotels |
| August | Mistura Food Festival (dates vary—check PromPerú) |
| October | Señor de los Milagros procession—one of the largest Catholic processions in the Americas |
| December | Christmas markets, New Year’s Eve fireworks on the Malecón |
What to Pack for Lima
Summer clothing (December–March):
- Light layers: t-shirts, linen shirts, light trousers
- One light sweater or jacket for evenings
- Swimwear for beach visits
Winter clothing (May–August):
- Mid-weight layers: long sleeves, light fleece or hoodie
- A windproof or waterproof outer layer (the garúa catches visitors off-guard)
- Avoid heavy wool—Lima’s cold is damp, not deep
Footwear:
- Comfortable walking shoes with grip (wet cobblestones in the historic center)
- Sandals for beach visits in summer
- Avoid open shoes in winter—damp surfaces make them impractical
Sun & weather protection:
- SPF 50+ sunscreen every day—UV index is extreme even through cloud cover
- Sunglasses year round
- Compact umbrella or packable rain jacket for garúa drizzle (June–September)
Seasonal Travel Tips
- Morning vs. afternoon: In winter, mornings are almost always overcast. Skies sometimes clear by midday. Plan outdoor activities for 11am–3pm where possible.
- The garúa is deceptive: Overcast skies do not reduce UV exposure. Sunscreen is non-negotiable even in July.
- Neighborhood microclimates: Miraflores and San Isidro, perched on coastal cliffs, catch more garúa than inland districts. The historic center is marginally clearer in winter.
- Book July early: If visiting in 2026 around Fiestas Patrias, secure accommodation 6–8 weeks ahead. Prices spike sharply around July 28–29.
- Reservations matter: Lima’s food scene is world-class and weather-independent. Book top restaurants (Central, Maido, Kjolle) well in advance regardless of month.
- Airport note: Jorge Chávez airport sits in Callao, close to the coast—often cloudier and cooler than central Lima even on summer days.
Weather Hazards in Lima by Month
Lima’s hazard profile is low overall, but a few risks are worth knowing before you visit Peru:
- Extreme UV: The average high UV index reaches 14–16 in January–February. Sunburn can occur within 15–20 minutes of unprotected exposure, even through light cloud. This is not a summer-only risk.
- Slippery surfaces: Wet cobblestones and tiled pavements in Barranco and the historic center become hazardous during garúa. Proper footwear matters.
- Air quality: Lima has moderate to poor air quality by global standards, particularly in traffic-heavy areas. Travelers with asthma should prepare accordingly.
- El Niño events: In strong El Niño years, unseasonable rainfall can affect northern Peru and occasionally Lima. This raises landslide risk in hillside communities near Lima and along Andean routes. Check SENAMHI advisories if traveling during a declared El Niño year.
- No altitude concerns: Lima is at sea level. Altitude sickness is not a factor here—save that preparation for Cusco, Arequipa, or routes into the Andes.
Key Takeaways
- Lima’s climate is arid coastal desert: mild temperatures year round, almost no rainfall, and high humidity throughout.
- The real seasonal divide is sunshine vs. cloud cover—summer (December to March) brings sun; winter (June to September) brings the garúa mist.
- Average temperature highs range from 18°C (64°F) in July to 27°C (81°F) in February—a narrow band by global standards.
- Humidity sits at 80–85% throughout the year and makes winters feel colder and summers feel stickier than the numbers suggest.
- July is the single busiest and most expensive month, driven by Peruvian national holidays and overlap with Andean dry season tourism.
- UV exposure is extreme year round—SPF 50+ sunscreen is non-negotiable, even on overcast winter days.
- For most first-time visitors, February, March, April, and November offer the best combination of weather, crowd levels, and value.
FAQs: Weather in Lima, Peru by Month
What is the best time to visit Lima for good weather?
February and March offer the most consistent sunshine, warm average temperatures, and lighter crowds than peak January. November is a strong shoulder-season option with improving skies and lower prices. For an accurate monthly weather forecast for Lima before booking, cross-reference these weather averages with live forecasts from a dedicated weather station near Lima.
Does it rain in Lima?
Almost never. Lima’s annual precipitation averages just 8–10mm—less than many true deserts. What visitors experience instead is the garúa, a fine coastal mist common from May to November, with no real accumulation. Lima essentially never rains in any disruptive sense.
Is Lima cold in winter (June–August)?
Not cold by alpine standards, but the combination of 14–18°C temperatures and persistent high humidity makes it feel raw, particularly in the mornings. A light fleece and windproof layer are sufficient for most travelers. The coolest, grayest period runs from June to September.
How does Lima’s climate compare to Cusco, Arequipa, or Iquitos?
The climate in Lima is completely different from all three. Cusco sits at 3,400m in the Andes with cold nights and a genuine rainy season. Arequipa is sunnier and drier. Iquitos is hot and tropical year round. Peru weather varies dramatically by region—Lima’s coastal mild temperatures make it the most moderate of the major cities.
How strong is the sun in Lima?
Stronger than most visitors expect. Lima’s UV index reaches 14–16 in summer—extreme by global standards. Even overcast winter months see UV levels of 8–10. Apply SPF 50+ sunscreen daily throughout the year, without exception.
