Weather & Climate

Zanzibar experiences ideal holiday weather for most of the year.  The heat of summer is seasonally often cooled by windy conditions, resulting in pleasant sea breezes, particularly on the North and East coasts. Being near to the equator, the islands are warm all year round, but officially, summer and winter peak in December and June respectively. This is illustrated statistical weather information shown below. Zanzibar is blessed with an average of 7-8 hours of sunshine daily.

Short rains can occur in November but are characterised by short showers which do not last long.  The long rains normally occur in April and May although this is often referred to as the ‘Green Season’, and it typically doesn’t rain every day during that time.
