You may have heard the terms “rainy season” and “dry season” for Belize. This is a myth we want to put to rest. Yes, there is more total rainfall in the country between June and November than there is during the other six months. However, it does not rain most of the time in those months, and in fact, most weeks are sunny and beautiful. It rains lots, lots more in the mountains and jungle than it does over the sea level cayes. A majority of the storms we get pass over quickly and come at night more often than not.


We’ve been asked this question hundreds of times, and it’s just what we would want to know before scheduling a dive vacation in Belize. So here we’ll share our decades of experience with the climate, month by month -- and then invite you down at a time that suits you best!

January & February: Wonderful mix of hottish and cool breezes. Daytime temps mid 70s to mid 80s. Water temp about 78.

March & April: Winds pick up as the weather prepares to shift. Daytime temps usually high 70s to low 80s. Water temp about 78 or 79. Underwater visibility excellent.

May: Transition from moderate to hot weather. Daytime temps increase to 90s by last part of May. Water temp rising to over 80. Visibility excellent.

June: Usually sunny and nice, but some storms will pass over. Daytime stays pretty warm, mid 80s to mid 90s. Water temp up to 84. Visibility still very good.

July, August, September, & October: Hot days with some very calm seas. Daytime temps mid 80s to high 90s. Water temp 84. Visibility drops as summer goes on, but still good almost every day. (This is when you will find the best deals of the year in Belize.)

November: Transitions from hot summer to moderate winter. Quite pleasant air temps. Water still very warm from summer sun. Underwater visibility increasing.

December: Can be cold for Belize (but not for North Americans!). Daytime temps low 70s to mid 80s. Water temp moving from over 80 to under 80. Visibility generally very good.
