Zanzibar · Month comparison
April vs June
June ranks #1 overall vs April at #12. The dry season opens — whale sharks arrive, ZIFF kicks off, and Zanzibar is at its most rewarding.
April
#12 of 12 months
Avoid
Long rains peak — avoid unless you specifically need a cheap, empty island with rain-tolerant plans.
- ↑Stone Town exploration remains viable during April — the historic quarter's narrow alleys, carved doors, and covered markets provide shelter, and the absence of tourists makes the culture genuinely accessible
- ↑The cheapest month of the year: resorts that remain open offer rates that would be unrecognisable to January visitors; for the very budget-conscious with flexibility and rain tolerance, April offers remarkable value
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

April trade-offs
- ↓295mm of rain in April is serious and persistent — this is the long rains (Masika) at their heaviest; sustained beach days are effectively impossible and outdoor activities require significant tolerance for tropical downpours
- ↓Many resorts, dive operators, kite schools, and tour operators close entirely for the long rains season; the island's tourism infrastructure is operating at minimum capacity
- ↓Sunshine drops to 5.0 hours daily and the Indian Ocean becomes rough and murky — snorkelling and diving conditions deteriorate markedly, and the brilliant turquoise water that defines the island's appeal is greyish and choppy
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
