UK sea temperature map and buoy readings
The ocean gradient shows the latest daily Met Office OSTIA sea-surface temperature analysis, with current wave buoy readings overlaid. Switch to anomaly view and the background changes to the latest long-term Copernicus Marine sea-temperature anomaly. Each buoy marker shows the long-term anomaly at that location, falling back to its short-term anomaly: how far the current reading is above or below its recent historical August average.
