July
#2 of 12 months

Peak dry season — whale sharks, ZIFF finale, Festival of the Dhow Countries, and perfect beach conditions.

- ↑Whale shark season peaks in July and August — encounters are more frequent than June and the south coast tours are fully operational with experienced guides and well-maintained equipment
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

July trade-offs
- ↓International school holidays bring European visitors in numbers — Stone Town's narrow lanes and the best beach positions are at their busiest for the year, and accommodation prices reflect demand
- ↓At 26°C, July is the coolest month of the year — ideal for activity but the evenings are genuinely cool; not the sweaty tropical heat of January, which some visitors prefer
- ↓The trade winds are at their most consistent — kite surfers love it, but swimmers and snorkellers on exposed beaches will encounter more chop than in the calmer months of December and January
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
