Enjoying a tropical climate, the Zanzibar Archipelago is hot to humid all year round, with two rainy seasons referred to as the “longs rains” and “short rains”. It is a great year-round destination, however, there are some more “desirable” divisions of the year that visitors are more fond of.
March to May – the “long rains”
March, April and May mark the main rainy season. Brewing clouds tend to build in the early afternoon and the storms are usually short and fierce. Very rarely do showers set in for a few consecutive days. The humidity is high and daily temperatures can reach the low-mid 30°C. Despite regular downpours, this time of year can still see some very good days. Expect warm sea waters (28°C), less crowds, as well as clear and crisp mornings.
June to October – the long dry season
June marks the start of Zanzibar’s long dry season, and is often the sunniest, driest month of the year. Winds pick up slightly, progressing into July, which may be a bit “blowy” for beach lounging, but is the ideal time for kitesurfing and other wind sports!
Moving through July to August, the winds slowly subside and surrounding seas drop to temperatures of around 25°C. Not too hot and not too humid August to October is perhaps the most pleasant period on the archipelago with slowly subsiding breezes from the south.
November to December – the “short rains”
November marks the month of the ‘short rains’ in Zanzibar, a brief period of sporadic storms that usually ease off during December. These are much lighter than the main rainy season, however consecutively cloudy days can be expected.
January to February – the short dry season
The short dry season is a period of relatively hot, humid weather which develops steadily from late December through to February. January is one of Zanzibar’s hotter months, with regular daytime highs up to 35°C. Although generally sunny, the start of the new year in Zanzibar can still feature the occasional afternoon thunderstorm which clear up quite quickly.
