Where Is the Sea Warmest Today?
Air temperature only tells you half the story — the water decides whether you actually swim. We measure sea surface temperature at close to 200 coastal destinations and rank the twenty warmest right now, with a comparison against the same date last year so you can see whether the sea is warmer or cooler than usual.
