UK & Ireland Rain Radar - 15-Minute Updates

About this rainfall radar data

This radar sequence is produced from the UK Composite Rainfall Radar dataset, jointly operated by the Met Office, Met Éireann, and Jersey Met, and distributed through the Met Office UK Radar Open Data service on the AWS Open Data Registry. The dataset provides nationwide precipitation scans every 15 minutes, and each frame is typically published around 15 minutes after it was captured and this viewer turns the frames into a clear, consistent timeline.

Radar works by sending out pulses of energy and measuring how much is reflected back by raindrops, hail, or snow. Stronger reflections appear as brighter colours, indicating heavier precipitation. Areas with no shading are generally dry, although very light drizzle or shallow cloud layers can sometimes go undetected.

Local Considerations

Radar coverage over South Devon is generally excellent, but hills on Dartmoor and the South Hams can occasionally create small shadows or reduced returns. Offshore, sea clutter may appear during certain atmospheric conditions.

Update Frequency

This page typically refreshes with new radar data 15 minutes after each 15-minute scan, so updates usually appear shortly after 00, 15, 30, and 45 minutes past the hour.
