Looking to find out what the sea water temperature in Thio is for today and the next few days? Below are data and charts that will give you information about sea temperatures in Thio and nearby locations.
Water temperature in Thio right now
Below is the current sea temperature for Thio, New Caledonia on 30th June 2025.
24.14° C
(75.46° F)
- yesterday: 25.49° C (77.88° F)
- a week ago: 25.46° C (77.83° F)
Water at this temperature is very pleasant to swim in and if you tend to wear a wetsuit when swimming, you might consider removing it now to avoid the body overheating.
The average sea temperature for Thio on June 30th over the last 10 years is 24.48° C (76.07° F), with a low temperature of 23.7° C (74.66° F) and a high of 25.55° C (77.99° F).
Analysis and forecast for Thio water temperatures
The water temperature in Thio today is lower than the average temperature of 24.48° C (76.07° F) and the temperature on this day last year, 30th June 2024, was 24.1° C (75.38° F).
The chart and table below shows the change in water temperature in Thio over the last 30 days:
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 Thio?
The ocean covers about 71% of the Earth's surface, and scientists record the sea surface temperature (SST) of locations such as Thio 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 Thio 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 Thio 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.
