Questions

Where is the sea warmest in August?

Inland Sea Beach, Qatar, at 34.1 °C — the highest August mean among the 2,330 beaches this atlas measures.

How many beaches are warm enough to swim in August?

1,619 of 2,330 reach 20 °C or more as a monthly mean. Twenty degrees is the line used throughout this atlas, and it is stated rather than implied because a swimming season is an opinion dressed as a number unless the threshold is on the page.

Where do these numbers come from?

NOAA's OISST v2.1 monthly long-term mean for 1991 to 2020, on a 0.25° global grid, sampled at each beach's own coordinates. It is a satellite and buoy record, in the public domain, and nothing on this page is estimated or written by hand.
