River Monitoring Stations in Denbighshire

Rainfall across north-west England and north Wales, year by year

Denbighshire sits in the Met Office's north-west England and north Wales area. Each bar is one year's total; the dark line is the ten-year average, which is what a trend looks like once single wet and dry years are smoothed out; the dashed line is the 1991–2020 average of 1,338 mm. 2025 brought 1,329 mm, close to that. The wettest year here since 1996 was 2000 (1,691 mm), the driest 1996 (1,021 mm).

Rainfall over a whole region, not a measurement in Denbighshire itself, and a wet year is not the same thing as a flood: what floods a river is how much falls at once and how wet the ground already was.
