Weather in Dar es Salaam in January

Shoulder season. January is shoulder season in Dar es Salaam — cheaper, quieter, and a genuine gamble. You should expect rain on 16 days of the month, which is more days wet than dry.

January ranks 8 of 12 in Dar es Salaam: past the worst of the year but short of July, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 16 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 30.1 °C days and 26.4 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 17 days top 30 °C — hot spells arrive, but they break; the day barely swings — 3.7 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 32.4 °C and the coldest night fell to 24.2 °C, and the wettest single day dropped 44 mm — roughly 49% of the month's rain in one day.

January is moderately variable: 32 mm in the driest year against 211 mm in the wettest, around an average of 90 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 15.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 77%, high enough to notice on the warm days without dominating them.

How January sits in the year

Temperatures hold steady either side: 30.2 °C in December, 30.1 here, 30.4 in February. Nothing about the timing within the month matters much. Rain has already shifted: 6 days fewer than December had.

Daylight in January

Dar es Salaam sits close enough to the equator that daylight barely moves all year — 12.5 hours in January, against a range of just 0.8 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 28.6 °C in January — warm enough that the water offers no relief from the heat. The sea peaks at 29.5 °C in March and bottoms out at 25.6 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Dar es Salaam versus nearby

If Dar es Salaam is one option among several, the nearby comparison is worth making. Zanzibar is a better bet in January — within a degree on temperature, 4 days less rain. Mombasa is the weaker option in January — 5.7 °C warmer, 10 days less rain.

So: January is a compromise. July is 34 points better and is what Dar es Salaam is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
