Everything below is collected in one spot so you do not have to cross-check Diyarbakir climate: monthly averages by hand. The gap between Jan and Jul is 30.0 C here: 0.7 C against 30.7 C. No month dominates: the wettest is Feb at 2.46 mm/day, the driest Aug at 0.02 mm/day. Taken together that is roughly 502 mm of rain a year for the grid cell.

What the Diyarbakir climate table shows
Values are multi-decadal climatological averages for the 37.9136, 40.2172 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
Is Diyarbakir climate data a forecast?
No. These are multi-decadal averages for the grid cell, not a prediction for any particular year.
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.
