Bîr Mogreïn has a hot desert climate.
Long, extreme summers. Mild winters. Very little rain in any month — here's what that means in plain terms.
What this climate feels like
The four things a regular visitor actually wants to know:
Highs near 42°C in August. About 180 days a year above 32 °C.
Lows near 9°C in January.
About 35 mm of rain a year. Wettest in October.
Clear skies most days.
What "hot desert" means
Climate scientists sort every place on Earth into about 30 climate types, based on how hot, cold, wet and dry it is across the year. Bîr Mogreïn's type — hot desert — sits in the broad family of dry climates — deserts and steppes.
Researchers write climate types as a short letter code. Here is what each letter means:
Cities with the same climate as Bîr Mogreïn
A hot desert climate (BWh) — these recognizable cities share it. If you know one of them, you know roughly what to expect.
Bîr Mogreïn sits near a climate boundary
This city's climate sits within about 2.2 °C of the next type along. A slightly cooler or warmer decade could change which side of the boundary it lands on — but the lived weather doesn't change at the line.
Has Bîr Mogreïn's climate type changed?
Stable — Bîr Mogreïn's climate has held the same type between the 1971–2000 and 1991–2020 normals. The label is steady; the climate beneath it is still warming.
What this climate means for you
Xeriscape only — native succulents, cactus, desert-adapted shrubs. Vegetable gardens need shade cloth and heavy irrigation; many crops simply won't survive summer.
Travel in the cool half of the year (Nov–Mar). Summer travel is uncomfortable and outdoor activity is limited to dawn and dusk.
Brutal summer heat shapes daily life — early mornings and evenings are the practical outdoor windows. Air conditioning is near-universal; sun protection and hydration are constants.
Where these numbers come from
The climate type and the month-by-month figures on this page are computed from Bîr Mogreïn's measured 30-year climate normals (1991–2020) — the same official records behind Bîr Mogreïn's main climate page, so the two always agree.
Long-range climate maps measure things slightly differently and can place a city in a neighbouring category. Where they differ, this page uses the measured station record as the climate today.
Methodology & sources
Temperature & precipitation — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.
