What you gain in May

  • Rainfall begins easing from April's peak and temperatures drop slightly to a more comfortable 28°C — the tail end of the long rains is marginally more tolerable than April even if still wet
  • Budget accommodation at exceptional rates continues — for safari-and-beach combinations where the beach days are treated as secondary, May offers the cheapest possible Zanzibar extension
  • A few tour operators and kite schools start reopening toward the end of May as the rains ease; timing a late-May visit correctly can mean low prices and improving conditions

What you sacrifice

  • 258mm of rain — still the long rainy season; May is not meaningfully better than April for beach purposes and the same infrastructure closures apply across most of the island
  • The combination of rain, humidity, and overcast skies makes Zanzibar in May feel oppressive rather than tropical; this is not the Indian Ocean paradise of the brochures
  • Mosquito and insect populations peak during and immediately after the rainy season — health precautions including antimalarials and repellent are non-negotiable
