How extreme does Cabo Rojo's weather get?

The hottest, coldest, wettest and snowiest days Cabo Rojo 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 Rincon station 30 km away. Updated through February 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 Cabo Rojo has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day

98°F Jun 13, 1971

That is about 14°F hotter than a normal June afternoon in Cabo Rojo (typical high near 84°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.

Cabo Rojo's record heat sits well above even a hot day for the season — June's 98°F is about 14°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, Cabo Rojo's warmest days reach the low 90s°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 −13°F. A single day has delivered over 5 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 12 years of daily observations at Rincon, a weather station, about 30 km from the city centre. The underlying daily records come from NOAA's global station network.
