If you only need Asmara climate: monthly averages, the figures and table here are the whole story. Asmara runs from 19.5 C in Jan to 26.5 C in Jun, a swing of 7.0 C. Rain is strongly seasonal: Aug is the wettest month at 4.66 mm/day, while Jan runs at 0.12 mm/day, about 38.8x drier. Taken together that is roughly 411 mm of rain a year for the grid cell. The build runs on a schedule and caches the last good response, so the numbers stay put even when the upstream API is having a bad day. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Asmara climate table shows
Values are multi-decadal climatological averages for the 15.3381, 38.9318 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
Why do the numbers differ from a weather app?
An app shows one location on one day. These are long-run averages, so they smooth out single hot or cold spells.
How much rain is 4.66 mm/day in a month?
Rain is recorded as a daily mean, so 4.66 mm/day is roughly 142 mm across a 30-day month.
