Weather and Tides

Chesapeake Bay Weather

weather-sunset-2The weather is important. Sometimes bad weather can just be an inconvenience, but other times, like when you’re out on the water, it can be dangerous. Never go out on the bay without checking the weather forecast.  Storms can roll through the Chesapeake quickly and thunderstorms can be fierce.

Even if the forecast is for nice weather, it’s good to know about wind strength and direction, particularly if you’re planning on sailing.

And, of course, anyone who’s spent time on the Bay knows that you need to be aware of high and low tides

This page contains Chesapeake Bay weather and tides information, including NWS Chesapeake Bay marine forecasts and links to real-time meteorological and tides information from data buoys located throughout the Chesapeake Bay.

Chesapeake Bay Water Temperature Maps

thermoicongifChesapeake 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.
