What to expectMusoma through the year

Musoma changes little through the year. Average daily highs stay between 27 and 27 °C, so no month stands out as a season in the way it would further from the equator.

Rain is strongly seasonal. April averages 175 mm against 24 mm in July — 7.3 times as much. Planning around the dry months matters more here than planning around temperature.
