Zanzibar October — a man rests on the beach beside a traditional boat as the island transitions into the short rains season

October

#6 of 12 months

Strong option

Pre-short rains shoulder season — warming up, occasional showers, and good value.

  • ↑Temperatures warm back up to 29°C as the island moves out of the cool dry season — the beach weather improves and the Indian Ocean water temperature climbs back toward its summer peak
  • ↑Low crowds and moderate prices make October one of the better value months for an independently minded traveller who can live with occasional showers
Zanzibar June — a man on a traditional sailing dhow off the Matemwe coastline as dry season begins

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

October trade-offs

  • ↓October sits in the pre-short rains period — rainfall of 72mm is moderate but showers are increasingly common; beach days are possible but not as reliable as July or August
  • ↓The island is in a transitional state: some seasonal operations have closed for the between-seasons period while others are in pre-season mode; the full Zanzibar experience requires some navigation
  • ↓Islamic calendar events including Idd el Fitr and Maulid (dates vary year to year) can affect some services and create periods of heightened local activity; check the Islamic calendar for your specific dates

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
