Seasonal Travel Tips for December
- Start days early. Sunrise occurs around 6:45 a.m. hourly variations exist, so plan early to avoid afternoon crowds.
- Stay hydrated constantly. Sun and humidity drain water faster than you think, even with warm temperatures.
- Plan your trip in advance. Book accommodations and hotel reservations mid-December onward when availability tightens and prices spike.
- Visit cenotes midday. Underground pools are coldest (and most refreshing) around 1–3 p.m., making this the best beach weather timing.
- Dine early or late. Restaurants hit peak times 7–9 p.m. Eating at 6 p.m. or 9:30 p.m. avoids waits.
- Avoid seaweed forecasts. Tulum occasionally sees Sargassum seaweed; check hourly beach conditions when planning beach excursions.
- Use reef-safe sunscreen only. Sunscreen containing oxybenzone is banned. Tulum’s cenotes and reefs are fragile.
