How extreme does Georgetown's weather get?

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

Based on 19 years of daily weather observations (2005–2024), from the E T Joshua Airport station 19 km away. Updated through August 2024 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

In plain terms

Across the record, Georgetown has reached as high as 102°F and as low as 60°F. A single day has delivered over 4 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 146 km from the city centre. The underlying daily records come from NOAA's global station network.
