April in Belize brings rising temperatures and the welcome “Iguana Rains”, the brief, cooling showers appearing up and down along the coast. Expect average highs of 85°F (29°C) and lows of 76°F (24°C) with an overall monthly average of about 80°F (27°C).High on the list of Belize’s many charms is a very comfortable tropical climate with an average yearly temperature of 84° F (29°C). Costal sea breezes and Belize’s large tracts of jungle and rainforests provide cooling relief even in the hottest summer months while winters can be cool but never very cold. In short, the climate is pretty much near perfect. April has less rainfall than the rest of the year, and when rain does come it is usually in mild, short bursts.
Even in winter the temperature in Belize rarely falls below 60°F (16°C), while throughout summer the mercury sits at around 86°F (30°C). Humidity is also fairly consistent at around 85 percent.
