How extreme does Horley's weather get?

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

Based on 33 years of daily weather observations (1992–present), from the Charlwood station 6 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 Horley has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Horley has reached as high as 104°F and as low as 10°F. A single day has delivered over 2 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 29 years of daily observations at Kenley Airfield, a weather station, about 15 km from the city centre. The underlying daily records come from NOAA's global station network.
