FAQ
Where does this water temperature come from?
From NOAA's National Data Buoy Center (NDBC). Each buoy measures the water temperature near the surface, usually about a meter down, and reports roughly every hour. We pull the latest reading for every buoy off Maui & Big Island.
How often does this page update?
Every time you load it. Readings come straight from NOAA and are at most about 30 minutes behind what NOAA has published.
Why is the buoy temperature different from the satellite chart?
A buoy measures one spot a meter or so below the surface. A satellite measures the skin of the water over a wide area. On calm, sunny afternoons the skin can read warmer than the water below it. More in our guide to ground-truthing SST with buoys.
