Planning a trip to Zanzibar in September? You’re in luck. September is one of the island’s best-kept secrets: great weather, fewer tourists, and crystal-clear waters make it a hidden gem for savvy travelers.
Here’s everything you need to know about the weather, what to pack, and why it might just be the perfect time to visit.
What’s Zanzibar Like in September?
Zanzibar in September marks the tail-end of the dry season. The skies are mostly clear, humidity is lower, and the gentle ocean breeze creates ideal beach conditions. While not as popular as July or August, September offers the same beautiful climate — without the high-season crowds.
It’s a perfect month for those looking to enjoy a laid-back island escape with pleasant temperatures and plenty of sunshine.
Weather Overview
Temperature and Humidity
Expect average daytime temperatures around 28–30°C (82–86°F). Nights are mild, rarely dropping below 22°C (72°F). Humidity is lower compared to earlier months, making it more comfortable for outdoor activities.
Rainfall and Sunshine Hours
September is part of the dry season, with very little rainfall — usually less than 40mm across the month. You’ll enjoy around 9 hours of sunshine per day, perfect for long beach days or exploring Stone Town.
Wind and Ocean Conditions
Winds are moderate in September, especially on the southeast coast — making it a great time for kitesurfing in places like Paje. Sea temperatures stay around 26–27°C (79–81°F), ideal for swimming, snorkeling, and diving.
Zanzibar Weather in September
Absolutely. September is often described as a “sweet spot” — warm, sunny, and less crowded. It’s ideal for:
Honeymooners and couples seeking peace and privacy
Photographers drawn to the island’s vivid skies and golden light
Divers and snorkelers chasing perfect underwater visibility
Safari travelers combining Tanzania’s mainland parks with a beach finale
Plus, you’ll find better rates on flights and accommodations than during peak season.
What to Pack for Zanzibar in September
Packing light is easy in September:
Light cotton clothing (t-shirts, shorts, sundresses)
Swimwear and cover-ups
A light sweater or scarf for the evenings
Reef-safe sunscreen, sunglasses, and a wide-brimmed hat
Water shoes or sandals for boat trips and coral beaches
Mosquito repellent is always a good idea, even though the risk is lower this time of year.
