December

#9 of 12 months

Strong option

The peak season returns — European winter escapees arrive, conditions improve rapidly from November's rains.

  • The short rains have typically ended by mid-December and conditions improve rapidly: sunshine hours climb back to 8.0 daily and the Indian Ocean returns to its brilliant turquoise clarity — the peak season beach experience begins again
  • Kite surfing remains excellent in December as the north-east monsoon continues — the combination of kite season and improving beach weather makes December a strong choice for dual-activity visitors

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

December trade-offs

  • Peak pricing returns: Christmas and New Year weeks push accommodation to annual maximum rates across quality properties; Nungwi and Kendwa beach resorts in particular need booking months in advance
  • Early December can still see residual rainfall from the short rains — the transition from November's wetter conditions to the reliable dry weather of January takes time; early December visitors should allow flexibility
  • The combination of high international demand and a genuinely small island means that popular excursions — Delos day trips, whale watching, spice tours — book out quickly in the Christmas period; plan the itinerary before arriving

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
