Weather in Dar es Salaam

February is the warmest month (average 28.2°C, high 30.2°C) and July is the coolest (average 25.2°C, low 22.9°C). That 3.0°C swing in monthly averages is the first thing to plan around in Dar es Salaam.

Rain is the monsoon runs from March to May, inside an annual total of 1131 mm. The wettest month is April at 258 mm; the driest is July at 12 mm. Dar es Salaam is in Tanzania at 6.8°S. The 2001–2020 NASA POWER daily record describes a monsoon climate with a sharp wet-dry split. On this site the months that score closest to a 22°C day, lighter rain, and moderate humidity are June, July, and August.

When the score favours a visit

The three months with the highest comfort score are June, July, and August: June (25.7°C average, 24 mm, 76% humidity); July (25.2°C average, 12 mm, 73% humidity); August (25.5°C average, 14 mm, 73% humidity). They fall in calendar order. The score rewards averages near 22°C, lower rainfall, and humidity near 60%. It is a climate score, not a festival or price calendar.

If you want the monsoon itself — fewer crowds, greener landscape, heavier rain — aim at March–May instead of the score.
