What to expectGeita through the year

Geita changes little through the year. Average daily highs stay between 26 and 28 °C, so no month stands out as a season in the way it would further from the equator.

Rain is strongly seasonal. November averages 213 mm against 8 mm in July — 26 times as much. Planning around the dry months matters more here than planning around temperature.
