What the Isiro climate table shows
Values are multi-decadal climatological averages for the 2.77391, 27.61603 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
How much rain is 8.28 mm/day in a month?
Rain is recorded as a daily mean, so 8.28 mm/day is roughly 252 mm across a 30-day month.
Does Isiro get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
