What Puerto Vallarta September Weather Feels Like
Puerto Vallarta weather in September brings tropical and saturated conditions. Mornings break clear and hot, with strong sun and minimal cloud cover until noon. By mid-afternoon, humidity peaks and cumulus clouds build rapidly. Rain arrives in intense but brief downpours, usually between 3 pm and 7 pm, before clearing by dusk. Evenings cool slightly but remain warm and muggy. As the month progresses, understanding the monthly weather patterns in Puerto Vallarta can help travelers prepare for the local conditions. Frequent afternoon showers contribute to the lush greenery that the region is known for, making it a beautiful time for sightseeing. However, packing lightweight rain gear is advisable for those planning to explore the outdoors during this vibrant month.
Walking and sightseeing are feasible in the morning and early afternoon. Malecón strolls, market visits, and beach time work best before 2 pm. Afternoon plans should include indoor backups: museums, galleries, shopping arcades, or your hotel restaurant. Many visitors embrace a siesta during the hottest hours, then venture out again after rain passes.
Average Temperature in Puerto Vallarta in September
Daytime average highs hover between 30–32°C (86–90°F), while nights feature a low temperature around 23–24°C (73–75°F). The heat is relentless but not unbearable. However, when combined with 85% humidity, the “feels-like” temperature climbs to 33–35°C (91–95°F). Sun exposure intensifies the sensation, so shade and sunscreen are non-negotiable. September rivals August as one of the year’s hottest months, and cooling marine water (29–30°C or 84–86°F) provides relief.
Precipitation and Rain in Puerto Vallarta in September
September is unambiguously the wettest month in Puerto Vallarta, averaging 358mm (14 inches) of precipitation. An average daily shower pattern sees downpours arriving almost daily, falling on roughly 14–17 days per month. The good news: rain typically falls in brief, heavy bursts rather than all-day drizzle. Most occur in the afternoon and evening, with mornings often dry and sunny. Storms pass quickly, leaving clear skies and fresh air in their wake. Tours and activities rarely get canceled outright, though timing flexibility is essential. Weather conditions shift rapidly, so an hourly forecast can help plan activities.
Humidity in Puerto Vallarta in September
Humidity peaks in September at 84–87%, making the air feel heavy and sticky. This level, combined with heat, can feel exhausting for extended outdoor activity, especially between noon and 4 pm. Those with respiratory sensitivity or who dislike muggy climates should consider other months. Light, breathable clothing and frequent hydration are critical. The tropical feel is relentless but manageable with proper planning.
Is Puerto Vallarta Busy in September? (Crowd Levels & Tourism)
September sees low to moderate crowd levels, depending on the specific week. Back-to-school season means fewer family trips from the US and Canada. However, the Mexican Independence Day weekend (September 13–16) drives a spike in domestic tourism and can triple hotel prices. Book early if you’re visiting mid-month. Outside that window, you’ll find quieter beaches, shorter restaurant waits, and negotiable room rates—sometimes 30–50% cheaper than winter peak season. Discover cooler pricing and lower crowds as an alternative to busier months.
Best Things to Do in Puerto Vallarta in September
- Beach time and swimming: Morning swims are perfect; water is warm year round (29–30°C). Go early before afternoon storms.
- Snorkeling at Los Arcos and Los Muertos: Afternoon rain doesn’t affect underwater visibility. Book morning boat tours from Los Muertos Pier to explore Los Arcos Marine Park.

Events & Festivals in September
September is Mexico’s most patriotic month, anchored by the Independence Day (Fiestas Patrias) celebration. Key events include:
- September 14: Charro Day. Mexican cowboys parade through downtown at 10 am in traditional embroidered jackets, sombreros, and mounted on decorated horses. Traditional bullfighting, calf roping, food, and dancing continue throughout the day.
- September 15: Independence Eve (Grito de Independencia). The central plaza fills with locals and visitors for the traditional “cry for independence” at sunset. Fireworks, mariachi music, dancing, and authentic Mexican food celebrate until late evening.
- September 16: Independence Day Parade. The main event features civic ceremonies, fire departments, charros, and elaborate floats winding through the Malecón and downtown streets.
These celebrations span mid-month and draw both domestic and international tourists, inflating prices and crowds mid-September.
What to Pack for Puerto Vallarta in September
- Clothing: Lightweight cotton t-shirts, tank tops, shorts, light dresses, and sundresses. A thin, long-sleeved shirt for sun protection and air-conditioned indoor spaces.
- Footwear: Sandals, flip-flops, and water shoes for beach walking. Closed-toe shoes for evening outings.
- Sun protection: High-SPF sunscreen (reapply often), a wide-brimmed hat, and UV-blocking sunglasses. UV index is consistently high (6–7).
- Rain gear: A lightweight rain poncho, compact umbrella, or packable rain jacket. Waterproof bag for electronics and documents.
- Swim gear: Swimsuit, rash guard (if preferred), and waterproof bag for wet items.
- Extras: Light sweater or shawl for heavily air-conditioned spaces. Quick-dry towel. Insect repellent (mosquitoes thrive in humid months).
Seasonal Travel Tips for September
- Start early. Beach visits, outdoor sightseeing, and water activities work best between 7 am and 1 pm, before afternoon heat peaks and rain approaches.
- Schedule around the afternoon rains. Reserve restaurant dinners and evening activities for after storms pass (typically 7 pm onward).
- Stay hydrated constantly. High humidity and heat accelerate dehydration. Carry a refillable water bottle and drink frequently.
- Book tours and water activities in the morning. Operators prioritize morning departures during rainy season to avoid afternoon weather cancellations.
- Embrace indoor midday activities. Museums, galleries, shopping, and spas offer relief and air-conditioning during the hottest hours.
- Venture out at sunset. Post-rain evenings are the best time to explore the Malecón, visit restaurants, and photograph the bay with cleared skies.
- Plan flexibility into your itinerary. Rain delays are normal; avoid back-to-back outdoor plans on consecutive days.
Weather Hazards in Puerto Vallarta in September
Heavy rainfall is the primary concern, though hazards are generally mild. Flash flooding can occur in low-lying areas or near drainage channels, but the city is well-managed. Afternoon electrical storms are common but typically brief. Heat exhaustion is a real risk for those unaccustomed to tropical climates; limit midday outdoor exertion and drink constantly. Hurricanes are extremely rare (the Bay of Banderas acts as a natural barrier), with major storms occurring roughly once every 30–40 years historically. Mosquitoes and sand flies are more active in humid months; insect repellent helps. Sun overexposure, even on cloudy days, can cause severe burns due to a high UV index.

FAQs
Will rain ruin my Puerto Vallarta vacation in September?
Unlikely. Rain falls in afternoon bursts (usually 1–2 hours) rather than all-day downpours, leaving mornings clear. Plan beach and outdoor time for 7 am–1 pm, then move indoors or rest during afternoon showers. Evening strolls after rain are often the best part of the day.
Is September safe during hurricane season?
Yes. September falls within the Atlantic hurricane season, but Puerto Vallarta is exceptionally sheltered by the Bay of Banderas, which acts as a natural barrier. Major hurricanes strike the area roughly once every 30–40 years historically. Local authorities monitor systems closely and alert visitors to any threats.
What’s the best time of day to visit the beach in September?
Early morning (7–10 am) offers the clearest skies, calmest seas, and fewest crowds. By noon, humidity and heat intensify. Afternoon rain is common, so most beach-goers return to their hotels by 2–3 pm. Sunset beaches (after 6:30 pm) work once rain clears and temperatures cool slightly.
Are hotel prices cheaper in September?
Yes, significantly. Outside the Independence Day weekend (mid-September), rates drop 30–50% compared to November–March peak season. September is an excellent month for budget-conscious travelers willing to embrace heat and occasional rain. Weather forecasts and seasonal charts show savings compared to winter months.
Should I visit during the Independence Day weekend?
Only if you’re interested in Mexico’s patriotic celebrations—parades, fireworks, mariachi, and authentic food festivals are spectacular. Book accommodations and restaurants well in advance, as prices spike and availability shrinks. Otherwise, avoid mid-September for lower costs and smaller crowds.
