Everything below is collected in one spot so you do not have to cross-check Djelfa climate: monthly averages by hand. The gap between Jan and Jul is 23.5 C here: 4.9 C against 28.4 C. No month dominates: the wettest is Oct at 1.20 mm/day, the driest Jul at 0.23 mm/day. Taken together that is roughly 288 mm of rain a year for the grid cell. Because each page is rebuilt independently, one unavailable upstream never takes the rest of the site down. The table underneath carries the per-month breakdown; the related pages cover the same dataset nearby.

What the Djelfa climate table shows
Values are multi-decadal climatological averages for the 34.67279, 3.263 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 1.20 mm/day in a month?
Rain is recorded as a daily mean, so 1.20 mm/day is roughly 36 mm across a 30-day month.
