Shows how far the sea surface temperature around Jersey currently differs from the 1991–2020 average for the time of year, using NOAA's near-real-time OISST dataset (typically 1–2 days behind, since it takes that long for the satellite analysis to process). Land areas are masked out since this is sea-only data.

COASTAL FLOOD RISK

HIGH TIDE OUTLOOK
LOADING HIGH TIDE OUTLOOK…
An indicative guide only — not an official warning. For each of the next four high tides it combines the predicted high-water height with the small lift from low air pressure (roughly 1cm per hPa below normal), plus onshore wind (south-easterly to south-westerly, which pushes water into St Aubin's Bay and St Clement) and wave height at that time. A big tide on its own is usually fine; the risk climbs when several of these line up. Thresholds are approximate and for guidance. Always follow official Jersey Met and gov.je tide warnings, and call 999 in an emergency.
