Weather extremes

How extreme does Ciales's weather get?

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

Based on 50+ years of daily weather observations (1971–present), from the San Juan L M Marin Intl Ap station 50 km away. Updated through June 2026 — 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 Ciales has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
98°F Oct 9, 1981

That is about 9°F hotter than a normal October afternoon in Ciales (typical high near 89°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.

Ciales's record heat sits well above even a hot day for the season — October's 98°F is about 9°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, Ciales's warmest days reach the high 80s°F and its coldest nights drop to the low 70s°F. But across the record it has gone as high as 98°F and as low as 63°F. A single day has delivered over 9 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 & precipitation — 1991–2020 normals computed from 19 years of daily observations at Corozal Substn, a weather station, about 12 km from the city centre. The underlying daily records come from NOAA's global station network.
