AUGUST WEATHER IN BELIZE 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. 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. With temperatures so consistent year round, Belize has two, rather than four seasons– the wet and the dry. During August temperatures in Belize begin to change as drier winds from the west replace the easterly sea breezes. August marks the “Little Dry”, as it is known, with a decrease in rainfall and rise in temperatures, which range from 86°F (30°C) highs to average lows of 78°F (26°C). Overall average temperature for August is still a pleasant 82°F (28°C).
