Weather in Belize City: What to Expect in Every Season

While Belize City certainly has a lot going for it in terms of sights, culture and attractions, one of its top draws for sun-loving tourists is its consistently warm weather. But, there are certain times of year when the weather is better than others.

Find out all you need to know about Belize City weather, from when you should expect the most sun to how likely it is for a hurricane to pop up on the radar. This complete guide will help you plan the perfect Belize City getaway.

Understanding Belize City Weather

As Caribbean destinations go, Belize City weather is fairly predictable. The overall climate is subtropical, the temperature doesn’t fluctuate too widely (71°F to 88°F on average), and humidity can be high but is often masked by the cooling sea breezes.

The city has two seasons: wet and dry. You can expect rain at any time of the year, but the wettest months are from June to November. Rainfall is usually a brief downpour during the day with longer showers overnight, so outdoor activities aren’t likely to be completely washed out by the rain.

Hurricane Season

Hurricane season is officially from June 1 to November 30. Only two Category 5 and three Category 4 hurricanes have gotten close to Belize in known history. The last one was Hurricane Dean in 2007. You can also plan around the peak hurricane season if you want to minimize the chance of your travels being thrown off. Of the 14 storm events that have occurred in or near Belize, the vast majority happened from August (5) and October (3).

While the chances of a hurricane ruining your vacation in Belize are low, it’s still important to be prepared if you’ll be traveling over this period. Hurricanes form over a period of many days and even weeks, so you should have ample warning to make alternative plans depending on the severity of the hurricane.

Booked a Caribbean cruise during hurricane season? That’s not a bad thing. Cruise prices can be low at this time, and if a hurricane does pop up on the radar, you’ll likely be diverted to another destination before you can even think to stress about it.

Belize’s National Emergency Management Organization and the United States’ National Hurricane Center are both great resources for tracking any potential hurricanes. You can also check out a Belize City cruise port webcam to see what the weather is like on the ground.

Northers

One more quirk of Belize City weather is a phenomenon known as northers or nortes. This is a name given to the cold air masses that come from the US between November and March and bring heavy rains and cooler temperatures.

Northers shouldn’t be disruptive to your vacation plans and can sometimes be seen as a welcome reprieve from the heat. If your activities include hiking through the rainforest or climbing to the top of a pyramid in Xunantunich or Altun Ha, northers mean cooler and moist conditions. Fishing and diving tours may be postponed due to the wind, however, so it’s worth scheduling any tours earlier in your trip so you don’t miss out.

What is the Best Time to Visit Belize for Good Weather?

The best time to visit Belize for good weather is from early January to mid-April. This is when the country experiences its dry season, with little rainfall and plenty of sunshine.

What is the Weather in Belize City Like in Spring?

The start of spring brings near idyllic temperatures. You’ll experience comfortable temperatures from 81°F - 83°F on average, and rainfall is at its lowest this season.

One thing to be aware of is that cloud cover rapidly increases over the course of spring. It starts at 23% in March and ends with 78% overcast or mostly cloudy days by the end of May. Spring is also your last opportunity to experience a few days without humidity levels at their most muggy.

Summer in Belize City is not for the faint of heart. It’s not the heat that will get you but rather the humidity and cloud cover. Humidity is at its highest this season, and the constant cloud cover means that the sky is overcast 80% of the time.

If you’re planning to be near the water, then this shouldn’t dissuade you from traveling to Belize. Book in your cave tubing tour or day trip to the Blue Hole with no fear, but you might want to think twice about any hikes to the top of a Mayan pyramid in the middle of the day.

Temperatures slowly start to drop in fall, and cloud cover dramatically drops away as the months progress. By the end of the season, you’ll see as many sunny days as cloudy ones, but rainfall does increase. Saying that, what you can usually expect is a couple of brief but heavy showers, often in the afternoons, that clear up as fast as they appear.

I usually plan any must-do activities for the morning and, if the weather cooperates, spend the afternoon relaxing at the pool or beach.

During winter, you’re likely to experience what locals call "northers," sporadic gusts of wind blowing from the north. These usually sweep through the coastal areas of Belize, so Belize City weather does get affected, but it’s felt mostly in the cayes. The water temperature also reaches its lowest point of the year with an average temperature of 80°F.

• Average daily high: 82°F

Plus, when it does rain, it’s more of a relief from the heat of the day and can make something like a cave tubing tour even more of an adventure.

What is the Weather Like in August in Belize City?

August is when you should start having your “Plan B” in case of a hurricane. Temperatures are also as high as they’re going to get, with highs getting into the 90s and essentially constant cloud cover keeping the humidity high.

September and October mark the height of the wet season and when Belize City gets the most amount of rain: an average of 5.8 inches in September and 11.4 days of precipitation. Outdoor activities are still possible as the rain tends to come and go fairly quickly but be prepared to be flexible.

An ATM cave tour is ideal for a rainy day adventure. You’re going to get wet anyway to enter the cave, and once you’re inside, the rain shouldn’t bother you.

What is the Weather Like in October in Belize City?

Belize City weather conditions in October are very similar to September, with a bump in how much rain you can expect this month. October averages 6.3 inches of rain and 11.9 days of precipitation.
