How extreme does Truro's weather get?

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

Based on 16 years of daily weather observations (2009–present), from the Newquay Cornwall station 19 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 Truro has recorded — each shown against what a normal day that time of year looks like.
