Each number is the latest Environment Agency station reading. Open its marker for the measured time, unit and datum.

Trend samples collected every 6 hours. Open an Environment Agency river-level marker for the net change over 1, 3 and 7 days and the latest sample time. Missing history is labelled; these changes are not a forecast or safety advice. Six-hour observations are retained for long-term history.

We build this rolling five-year seasonal reference from Environment Agency readings as they arrive, polling every 15 minutes. We first calculate each day’s median, then compare daily medians from the same calendar month: P10, P50 and P90 are the 10th, 50th and 90th percentiles, and P10–P90 spans the middle 80% of qualifying records. A station-month appears only after at least 30 valid days across 3 or more years. The record is still building until five years have accumulated.

These are historical comparisons, not a flood warning, water depth, forecast or safety assessment. Readings and coverage vary by station; check current official conditions before setting off.
