Zanzibar Weather & Best time to visit
October 17, 2025
You think of white sand and spice markets, but the question is always the same. When is the best time to visit Zanzibar?
You want to land when skies open wide, seas stay calm, and streets invite slow walks without the weight of heat or rain pressing too hard. Timing shapes your trip.
Choose well, and the island feels like it was waiting for you. Choose poorly, and you might spend afternoons watching clouds from under a roof instead of the shade of a palm.
Zanzibar sits near the equator, so temperatures remains warm most of the year. What shifts most are rains, winds, and crowds. You do not pick the best time by thermometer numbers alone.
You pick it by the kind of days you want. Long swims, spice tours, Stone Town wanderings, or kite-filled skies each fit better in certain windows.
From June to October, skies clear, air cools slightly, and humidity drops. This is the stretch many call perfect. Days run around 28°C (82°F), nights soften enough for sleep, and rain rarely interrupts.
During this time, beaches stay bright, seas calmer, and streets in Stone Town walkable without sweat becoming your main memory.
If you plan safaris on the mainland before or after, this window also matches the best season for Tanzania’s northern parks. That is why flights and hotels fill early.
Costs rise, yet comfort and views are incredible.
January and February bring another dry season and favorable for visiting Zanzibar. Heat rises more, and some afternoons feel heavy, but skies stay mostly blue. These weeks suit travelers who want fewer crowds and still good weather.
The sea feels warm, perfect for diving and snorkeling. Winds pick up enough for kitesurfing, especially along the east coast.
It is hot, yes, but if you pace your days with early walks, midday shade, and late swims, it works well. For honeymooners, this period often feels quieter and more intimate as there are relatively fewer crowds.
March to May mark the heavy wet season and it’s not recommended but people still visit. Clouds gather fast, showers fall heavy, and humidity peaks. Some days you wake to gray, some afternoons vanish to sudden downpours, and streets shine with puddles.
If your dream trip involves long beach days, this season challenges you. Yet it holds its own charm. Fewer visitors mean lower costs. The green of plantations deepens, air feels washed, and you hear the island breathe differently. If you travel with patience, you may enjoy a richer, quieter view of Zanzibar. But it asks you to surrender control of the clock.
November and early December come with lighter rains and festive. Showers sweep in, clear fast, and leave skies patchy with sun.
It is not as wet as March to May. If you accept the chance of one or two damp hours, you gain softer light for photos, good diving, and lower room rates before the December holiday rush.
The balance works for travelers who do not need perfection. A beach under half-cloud can feel more personal than one under glaring noon sun.
In July or August, expect lively Stone Town nights, busy beaches in Nungwi, and kite schools filled with students on the east coast.
In September, crowds thin but weather still holds strong. In January, you may find yourself sharing a café with locals more than tourists. In April, you may walk lanes nearly alone, hearing rain on carved doors, then catching a rainbow over the port.
Best time is not really clear because it all depends on the story you want.
| Season | Weather feel | Who it suits | What to expect |
| June–Oct | Dry, cooler, clear | First-time visitors, families, safari add-ons | Calm seas, busy hotels, higher prices |
| Jan–Feb | Warm, mostly dry | Honeymooners, divers, kitesurfers | Hotter afternoons, fewer crowds |
| March–May | Long rains, humid | Budget travelers, slow explorers | Heavy showers, lush scenery, lower rates |
| Nov–Dec | Short rains, mixed sun | Flexible travelers, photographers | Quick showers, softer light, fair prices |
They may smile and say every time is a good time. And in a sense, they are right. Islanders adjust pace to the weather. Life continues in rain or shine. If you accept that rhythm, you will find joy even on a cloudy day.
If you prefer control and clear skies, you know your answer: book the dry season. Both choices work. It depends whether you want comfort guaranteed or surprise embraced.
