All seas and gulfs of the world
The world’s seas range from the warm Mediterranean and Caribbean to the cool North and Baltic seas. In summer the warmest for a holiday are the Red, Arabian, Caribbean and Mediterranean seas, staying at +26…+30 °C. We combine measured sea-surface temperature (SST) with the climate norm. Values are shown for each coastal city separately, so different shores of the same sea can differ noticeably. Pick a sea to see water temperature by coastal city and resort, a daily forecast and monthly averages — handy for planning a trip.
