Water temperature in Ishikawa right now

Below is the current sea temperature for Ishikawa, Japan on 19th April 2024.

14.07° C

(57.32° F)

  • yesterday: 13.84° C (56.91° F)
  • a week ago: 12.7° C (54.86° 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 Ishikawa on April 19th over the last 10 years is 12.59° C (54.66° F), with a low temperature of 11.18° C (52.12° F) and a high of 14.11° C (57.4° 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.

Ishikawa map and nearby water temperatures

The highest temperature in Japan today is 25.64° C (78.15° F) in Yonakuni. The lowest is in Hojo, where the temperature of the water is 1.83° C (35.29° F).

Why measure sea surface temperatures (SST) in Ishikawa?

The ocean covers about 71% of the Earth's surface, and scientists record the sea surface temperature (SST) of locations such as Ishikawa 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 Ishikawa 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 Ishikawa 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.
