Belize at a Glance: Dry Season vs Rainy Season
Belize's climate is pure tropical bliss. Average yearly temperatures hover around 27°C (80°F), with humidity that feels like a warm hug.
Dry Season (December to May): Sunny skies, low rain, and peak vibes. This is when everyone flocks in, and for good reason. Expect 27–31°C (80–88°F) days, cooler evenings, and crystal-clear waters for snorkeling and diving.
Rainy/Green Season (June to November): Lush, vibrant, and often cheaper. Short afternoon showers keep things fresh. It is still warm at 28–32°C (82–90°F), but the jungles are greener, and crowds are fewer.
Pro tip: Hurricanes are rare but possible from June to October. Travel insurance is important during this time, but if you're going to shell out for insurance, make sure your policy covers hurricane risk.
Peak hurricane season runs from August to October. This is when the risk of tropical storms and hurricanes is highest. While major hits are not common, they can lead to hotel closures, flight disruptions, power outages, and last-minute changes. Not only that, but due to low occupancy in September and October, many resorts close for weeks or months at a time in the fall to renovate, allow their staff to rest, and prepare for the next year's busy season. Some travel insurance policies charge higher premiums or have limited coverage during these months. We always recommend comprehensive coverage and building in flexibility for your custom itinerary.
Water temperatures are always swimmable, from 26°C (79°F) in winter to 30°C (86°F) in fall.

Micro-Climates in Belize: Why Location Matters
Belize may be small, but it has distinct microclimates that can make or break your trip:
- Coastal areas (Ambergris Caye, Placencia, San Pedro): Breezy and consistent thanks to Caribbean trade winds.
- Inland Cayo District (including Maya Mountains): Slightly cooler temperatures and more afternoon showers.
- Northern Belize (near Corozal): Hotter and drier.
- Southern Belize (around Punta Gorda): Wetter and lusher year-round.
When we craft your tailor-made Belize trips, we match the right region to your weather preferences. Beach lovers thrive on the cayes, while jungle adventurers love the cooler Cayo vibes.
