Belize Weather Guide

The season, and who to watch.

The hurricane season is from 1 June to 30 November. The advice names the bodies to monitor rather than leaving you to find them: the US National Hurricane Center's regional map and the National Meteorological Service of Belize for the weather itself, and the National Emergency Management Organisation for what to do about it. Those are the three to bookmark before a trip in the second half of the year, and the third is the one that matters once you are there.

Flooding is a separate risk and it does not need a storm.

The same advice states simply that heavy rainfall can cause flooding, and points to the National Hydrological Service for forecasts. This is the quieter of the two weather risks and the likelier to affect an itinerary: an inland road or a river crossing can be out for reasons that never make international news.

There is a related note in the advice worth carrying: domestic air travel across Belize's municipal airstrips can be disrupted, and you may wish to allow extra time. If your plan involves a short internal flight to catch an international one, that is the sentence to plan around.

Why there are no numbers here.

You will find no average temperature, no monthly rainfall table and no sea temperature on this page. That is not an oversight. No source in this cluster's register publishes them for Belize, and this series does not print a figure it cannot attribute.

It is worth being clear about what that does and does not mean. It does not mean the information is unobtainable; the National Meteorological Service of Belize publishes for its own country and is the right place to ask. It means that we have not read it, and so we do not repeat it as though we had.

What can be said without a number is that the season above governs the second half of the year, and that the best time to visit guide sets out the non-weather constraint that decides more itineraries than the weather does.

If you would like a trip planned around the drier part of the year, or one built to absorb a disrupted boat or airstrip day, tell us which.
