Weather extremes

How extreme does Cruz Bay's weather get?

The hottest, coldest, wettest and snowiest days Cruz Bay 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 (1972–present), from the Cyril E King Ap station 20 km away. Updated through May 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 Cruz Bay has recorded — each shown against what a normal day that time of year looks like.

🔥 Hottest day
110°F May 5, 2024

That is about 23°F hotter than a normal May afternoon in Cruz Bay (typical high near 87°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.

Cruz Bay's record heat sits well above even a hot day for the season — May's 110°F is about 23°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, Cruz Bay'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 110°F and as low as −58°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 27 years of daily observations at Cyril E King AP, a weather station, about 20 km from the city centre. The underlying daily records come from NOAA's global station network.
