Looking to find out what the sea water temperature in Birkenhead is for today and the next few days? Below are data and charts that will give you information about sea temperatures in Birkenhead and nearby locations.
Water temperature in Birkenhead right now
Below is the current sea temperature for Birkenhead, Australia on 23rd June 2025.
14.29° C
(57.73° F)
- yesterday: 14.72° C (58.5° F)
- a week ago: 14.36° C (57.85° 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 Birkenhead on June 23rd over the last 10 years is 14.44° C (57.99° F), with a low temperature of 13.76° C (56.77° F) and a high of 15.39° C (59.7° F).
Analysis and forecast for Birkenhead water temperatures
The water temperature in Birkenhead today is lower than the average temperature of 14.44° C (57.99° F) and the temperature on this day last year, 23rd June 2024, was 14.34° C (57.81° 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 Birkenhead?
The ocean covers about 71% of the Earth's surface, and scientists record the sea surface temperature (SST) of locations such as Birkenhead 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 Birkenhead 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 Birkenhead 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.
