Swellinfo Ocean Temperature improved

New data used to improve sea surface temperatures

Sea surface temperatures can make or break your surf session if you do or do not have the right wetsuit gear or don't know what to expect. That is why we, at Swellinfo, thought it was important to make advancements on reporting the ocean temperature for each local area.

Swellinfo now uses a combination of coastal buoy data and satellite derived data to report the sea surface temperature for each local surf forecast region. There is a great deal of both spatial and temporal variability with sea surface temperatures. The best method for gauging the water temperature is of course manually with a thermometer. Unfortunately, that is beyond the scope of the Swellinfo forces. Where possible, we use the next best thing - coastal buoy measurement that are nearby. Coastal buoy data accounts for about 60% of the US forecast locations, but unfortunately 0% outside of the US due to the lack of data. When a nearby coastal buoy is not available, the Satellite derived data is used. Below is the live high resolution sea surface temperature dataset (you can zoom in/out and navigate to different regions with the nav button on the top left).

Overall, the new data will allow for improvement in the sea surface temperature's being reported, but unfortunately there are still some caveats with the Satellite derived temperatures. The biggest problem is is that the data is only available for the previous day. Often, this will be very accurate, but if the sea surface temperatures change substantially in a 24 hour period, then there will be a lag period of 24 hours or so before the change is reported on Swellinfo.
