What this means

The River Thames at Days Lock is well above normal at 0.19 m.

The median for mid-October is 0.12 m, based on 21 years of readings, so the river level is 0.08 m above typical. On the same day last year the reading was 0.16 m, a difference of +0.03 m. The record high is 1.63 m, set on January 6, 2024.

It has risen 0.02 m over the past 24 hours. If the rise continues, low-lying paths and riverside parking can go under water. In the last month it has stayed between 0.17 m and 0.20 m.

Autumn rain usually starts to lift rivers again after the summer low.

Flood levels and safety

A high reading on its own does not mean property is at risk. The warnings issued by the Environment Agency take local defences and the forecast into account.

Readings can change quickly after heavy rain upstream, so check again before heading near the water.
