Bill Milne lives in Sykesville and asks, "Where is the water temperature taken for the 'Chesapeake Bay' entry? Likewise, what is the location used for the 'Upper Chesapeake Bay' wind direction, speed and wave heights predictions?" Our water temperature data was coming from the Chesapeake bridge-tunnel, near Norfolk, Va. Your query prompted a change to Tolchester Beach. "Upper Chesapeake Bay" wind and waves forecast covers Pooles Island to Sandy Point.
