September sits inside the June-to-October dry season and regulars describe it simply as dry and pleasantly hot - our 21.9mm falls across 7.1 days, so those are showers rather than rain. The decision they want you to make is which coast. The kusi, the south-easterly, blows through September and October and the east side takes it; that is breezy relief to some people and a nuisance to others, and the west is the still, hotter alternative. Our 18.8 kph is an island average and hides that split. Days reach 30.6C but read as 34C at 75 percent humidity, with a 26.6C sea and nights that only fall to 22.1C. The record: 11.1 hours of sun and AQI 31, among the cleanest air in the collection.

Forum posters describe January in Tanzania as hot and humid, sitting in the middle of the region's summer, with typical daytime highs in the 80sF and lows ranging from the upper 50s to low 70sF depending on location. Posters describe January as marking the end of the shorter 'vuli' rains and the start of a short, drier season that lasts a few months before heavier rains return in earnest around March, though posters note some lingering rain is still typical in January and February. Posters describe northern Tanzania specifically as often the hottest and most humid part of the country this time of year. Posters generally recommend short sleeves and light clothing for a January visit to Dar es Salaam, packing for heat and humidity as the dominant conditions.

July is winter on the Tanzanian coast, which sounds worse than it is: days near 27°C, nights around 23, and a sea still at 26°C. It sits inside the dry season, roughly June to October, and the forum describes it as sometimes cloudy but rarely raining — the best stretch of the year for beach days, snorkelling and diving, and noticeably more comfortable than the hot, humid months. Two practical notes regulars add: the coast stays warm and humid day and night whatever the "winter" label suggests, and evenings mean long sleeves — for mosquitoes rather than for warmth. The coast fills up as July goes on.
