How extreme does Gros Islet's weather get?

The hottest, coldest, wettest and snowiest days Gros Islet 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 George F L Charles Airport station 8 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.

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 59 km from the city centre. The underlying daily records come from NOAA's global station network.
