Chesapeake Bay Water Temperature Maps:

Chesapeake Bay water temperatures vary from lows in mid 30's during the winter to highs in the mid 80's during the summer.  Water temperature affects fish populations in the Chesapeake Bay.  This is a good resource to use to gauge where certain species of fish might be found throughout the year.

View current conditions from about 30 different data buoys located around the Chesapeake Bay and tributaries.  Information displayed includes wind direction, wind speed, atmospheric pressure, air temperature, and dew point.  Select a data buoy from a map of Chesapeake Bay buoys.

Chesapeake Bay Interpretive Buoy System:

NOAA's Smart Buoys provide real-time weather and water observations and interpret locations along the Captain John Smith Chesapeake National Historic Trail.  There are three buoys in place at this time, they are located in the James River, at the mouth of the Potomac River, and in the Patpsco River, near Baltimore.  Information from these buoys is available online or by calling 1-877-Buoy-Bay.
