How extreme does Roseau's weather get?

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

Based on 20 years of daily weather observations (2005–present), from the Canefield Airport station 4 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 Roseau has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Roseau has reached as high as 101°F and as low as 62°F. A single day has delivered over 19 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 10 years of daily observations at LE Lamentin, a weather station, about 89 km from the city centre. The underlying daily records come from NOAA's global station network.
