When is the Best Time to Visit Zanzibar?

Zanzibar sits just south of the equator, giving it a tropical climate year-round. Temperatures rarely dip below 24°C or rise above 33°C, and the sea is always warm. But the island has distinct wet and dry seasons, and getting your timing right makes a significant difference to your trip.

The Best Time: June to October (Long Dry Season)

This is the most popular and reliably good time to visit Zanzibar. The long dry season brings clear skies, low humidity, and calm seas. It's peak season, so accommodation is more expensive and popular spots are busier, but conditions are excellent for all activities — beaches, snorkelling, diving, and sightseeing.

• ✦June–October: Best overall conditions
• ✦July–August: Whale shark season around Mafia Island (a short flight away)
• ✦Clear visibility for snorkelling and diving
• ✦Ideal for kite surfing in Paje (trade winds are strongest June–September)

Also Great: November to February (Short Dry Season)

The short dry season is Zanzibar's second-best time to visit, and often preferable to peak season because it's quieter and cheaper. Skies are mostly clear, temperatures are warm, and the sea is calm on the west coast. This is an excellent time for beach holidays and water sports.

Avoid: March to May (Long Rains)

The masika — or long rains — fall from mid-March to end of May. This is Zanzibar's wettest period, with heavy daily downpours that can last hours. Roads flood, some smaller guesthouses close, and many activities are disrupted. We'd recommend avoiding this period unless you're on a very tight budget (prices drop dramatically).

Mixed Bag: November (Short Rains)

The short rainy season falls in November (sometimes extending into early December). Rainfall is much lighter than the long rains — typically brief afternoon showers that clear quickly. Many travellers visit in November and have a perfectly fine holiday.

Month-by-Month Summary

• ✦January–February: Warm, dry, quiet — excellent value
• ✦March–May: Heavy rains — avoid if possible
• ✦June–August: Peak season — best conditions, higher prices
• ✦September–October: Still excellent, prices beginning to ease
• ✦November: Short rains — brief showers, good value
• ✦December: Busy over Christmas, quieter in late December

Our Recommendation

For the best combination of good weather, reasonable prices and fewer crowds, visit in January–February or September–October. If you want guaranteed sunshine and don't mind paying peak prices, go in July or August.
