Weather extremes

How extreme does Mascara's weather get?

The hottest, coldest, wettest and snowiest days Mascara has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 42 years of daily weather observations (1983–present), from the Ghriss station 21 km away. Updated through August 2025 — 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 Mascara has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
116°F Jul 11, 2023

That is about 19°F hotter than a normal July afternoon in Mascara (typical high near 97°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.

Mascara's record heat sits well above even a hot day for the season — July's 116°F is about 19°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, Mascara's warmest days reach the high 90s°F and its coldest nights drop to the high 30s°F. But across the record it has gone as high as 116°F and as low as 21°F. A single day has delivered over 4 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
Methodology & sources

Temperature — modelled for this location from ERA5-Land reanalysis, a ~9 km global grid, because no long-record weather station is close enough to use.

Precipitation — 1991–2020 normals computed from 4 years of daily observations at Mascara-matemore, a weather station, about 27 km from the city centre. The underlying daily records come from NOAA's global station network.
