12.58° C
(54.64° F)
- yesterday: 12.37° C (54.26° F)
- a week ago: 13.19° C (55.74° F)
Water at this temperature is cold and will feel very cold initially, but the body will get used to it and longer swims are possible. Experienced swimmers can manage several hours of swimming, however hypothermia is still a very big risk.
The average sea temperature for Sainte Helene on April 19th over the last 10 years is 12.55° C (54.59° F), with a low temperature of 10.97° C (51.75° F) and a high of 13.74° C (56.73° F).

The actual nearshore temperatures may vary by several degrees and this can also be heavily affected by weather. Strong winds can cause cold, deep waters to replace the surface waters that had been warmed by the sun, and heavy rain can also reduce the temperature of the sea surface temperature as well.

Why measure sea surface temperatures (SST) in Sainte Helene?
The ocean covers about 71% of the Earth's surface, and scientists record the sea surface temperature (SST) of locations such as Sainte Helene because they want to understand and learn how the ocean communicates with the atomosphere of Earth.
SST is one measure that provides information on the global climate, and it can be used to predict the weather in Sainte Helene as well as atmospheric model simulations and to study marine ecosystems in the area.
Data source and citation
Raw data for the calculations made to find the sea surface temperature in Sainte Helene comes from the National Oceanic and Atmospheric Administration (NOAA) and their 1/4° daily Optimum Interpolation Sea Surface Temperature.
The water temperature data is constructed by combining observations from different platforms (satellites, ships, buoys, and Argo floats) on a regular global grid. A spatially complete sea surface temperature map is then built by interpolating to fill in gaps in the data.
