The hottest, coldest, wettest and snowiest days Tonypandy has
recorded — the outer limits of what its weather can do, and how far
they sit beyond a normal day.
Based on 24 years of daily weather observations (2001–present), from the St Athan station 24 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.

In plain terms
In a normal year, Tonypandy's warmest days reach the high 50s°F and its coldest nights drop to the mid-30s°F. But across the record it has gone as high as 92°F and as low as 6°F. A single day has delivered over 3 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.
