The temperature estimates in the charts are composite values calculated based on night-time observations from several satellite instruments. The temperature value represents the readings from a one-kilometer square at the location marked on the chart. Data is downloaded daily.   Click here to see the sea surface temperature map.

• These charts are useful to assess temperature trends; they do not reflect the maximum daytime temperatures, which will normally be higher than the values shown in the graphs. For more resources, see Shellfish Harvesting & Control.
