Questions

Where is the sea warmest in May?

Bang Saen, Thailand, at 30.6 °C, the highest May mean among the 4,050 beaches this atlas measures.

How many beaches are warm enough to swim in May?

1,387 of 4,050 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.
