Zanzibar · Month comparison
November vs June
June ranks #1 overall vs November at #8. The dry season opens — whale sharks arrive, ZIFF kicks off, and Zanzibar is at its most rewarding.
November
#8 of 12 months
Strong option
Short rains (Vuli) — wetter than October but shorter and more manageable than the April long rains.
- ↑The short rains (Vuli) are meaningfully different from the April–May long rains: showers tend to be intense but brief, often clearing within an hour, with sunshine following — beach days are still possible in a way they aren't in April
- ↑Kite surfing at Paje is excellent in November — the north-east trade winds blow strongly and consistently, making it one of the best kite surfing months; the flat-water lagoon is in ideal condition
June
#1 of 12 months
Best match
The dry season opens — whale sharks arrive, ZIFF kicks off, and Zanzibar is at its most rewarding.
- ↑Whale shark season begins (June–September) — snorkelling with whale sharks off the south coast near Diani is one of East Africa's most extraordinary wildlife encounters, and Zanzibar is one of the most reliable locations in the world for it
- ↑Zanzibar International Film Festival (ZIFF) runs in late June to early July — Stone Town's Old Fort hosts outdoor screenings, concerts, and cultural events in what is the island's most important annual event after Sauti za Busara

November trade-offs
- ↓148mm of rain is significant — November is wetter than any month in the dry season and outdoor plans need flexibility; some days will be genuinely rainy and the beach unusable
- ↓Some resort facilities and tour operators scale back for the short rains; not the full closures of April–May, but the operational infrastructure is not at peak capacity
- ↓Humidity climbs back toward 78% as temperatures rise and the rains bring moisture — the cool, dry comfort of July and August has ended; the combination of heat and wetness can feel oppressive
June trade-offs
- ↓It's the coolest month of the year by Zanzibar standards at 27°C — still warm, but the evenings can feel genuinely cool for those acclimatised to tropical heat; bring a light layer for Stone Town evenings
- ↓The south-east trade winds (kaskazi) blow through June with some strength — excellent for kite surfers but creating choppier conditions for snorkelling on exposed reefs
- ↓ZIFF brings a spike in Stone Town accommodation demand in its specific week — book ahead for the festival period
