Seasonal Overview: What the Calendar Looks Like
Zanzibar’s climate is classified as tropical, with two main seasons: a wet season from late March to June and a dry season from July to December. However, within these broad periods lie subtle variations that affect temperatures, humidity, and activities.
Dry Season (July to September)
These months bring the lowest humidity and plenty of sunshine. Daily highs hover around 30–32°C (86–90°F). The sea is calm, making it ideal for snorkeling and diving.
Late Dry Season (October to November)
Temperatures remain high, while rainfall starts to increase slightly. Yet sea conditions stay favorable, and the island’s flora bursts into green.
Wet Season (December to March)
Expect short, intense showers, especially in the evenings. Temperatures dip slightly, but the lush landscapes and vibrant fish schools make snorkeling worthwhile.
Early Wet Season (April to May)
Rainfall peaks, yet the rains are brief. The island turns a deeper green, and the coral reefs thrive. Ideal for those who prefer fewer crowds.
Monsoon Impact (June)
June sees variable weather. Rain can be heavy, and sea conditions might be rougher. Travelers often split the month between quieter inland areas and beach fronts.
