These water temperatures are climatological averages based on observations from
NOAA/National Ocean Service tide stations and NOAA/National Weather Service buoys.
They were computed from records ranging from several years to several decades.
Although ocean conditions vary from year to year, water temperatures are less variable than air temperatures,
so these averages can provide useful information for planning beach activities such as swimming or fishing.
