Riyadh's weather extremes

The hottest, coldest, wettest and snowiest days Riyadh has recorded — the outer limits of what its weather can do. This station's daily record ended in 2022, so these are historical extremes from that period, not records updated to today.

Based on 49 years of daily weather observations (1973–2022), from the Riyadh Obs. (O.A.P. station 2 km away. Updated through February 2022 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Riyadh has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
118°F Jul 25, 1987

That is about 8°F hotter than a normal July afternoon in Riyadh (typical high near 110°F).

How hot and cold it gets, month by month

The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.

Riyadh's record heat sits well above even a hot day for the season — July's 118°F is about 8°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.

In plain terms

In a normal year, Riyadh's warmest days reach the low 110s°F and its coldest nights drop to the high 40s°F. But across the record it has gone as high as 118°F and as low as 28°F. A single day has delivered over 31 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
