EMBERJambiani, on Zanzibar's southeast coast, enjoys warm weather all year round — but the time you choose completely changes the experience, from how often it rains to how the sea looks in front of the hotel.
June to October is the dry season, with the southerly wind (Kusi) cooling the air and temperatures between 24 and 29°C. It's the favorite period for most travelers: clear skies, lower humidity and slightly livelier seas from the south, good for those who enjoy a strong breeze.
December to February is the hot, dry season, with temperatures up to 31°C and the least rain of the year. The water is warm and the air is calm — ideal for long days on the beach and swimming.
November brings the short rains, known locally as "Vuli": showers that pass quickly, usually in the afternoon, followed by sunshine. They won't ruin a holiday, but it's worth having a plan B for a few hours a day.
March to May is the long-rains season, "Masika" — the wettest period of the year, with more frequent and longer showers. Many hotels in the area offer reduced rates during this period, so it can be a good option if budget matters more than guaranteed sunshine.
One important detail, specific to Zanzibar's east coast: the tide. At low tide, the water retreats hundreds of meters over the coral flat, and swimming straight from the beach becomes difficult for a few hours a day — the tide schedule matters as much as the season when you're planning your beach days. The Ember front desk gives you the exact tide times for your stay every day, so you always know when it's the right moment for a long swim or a walk on the exposed reef.
In short: July to October and December to February are the safest choices for sunshine and calm seas; November and March to May are less predictable, but bring quiet and often better prices.
