Water Temperature Line Plots

Water temperature can be viewed through time at select locations to understand the seasonal and short-term changes in temperature in the Chesapeake Bay. Overlaying the modeled temperature on top of long-term averages from observed data shows how the forecasted temperature compares to the historical average. Grey lines show one standard deviation above and below the average.

Difference From Long-Term Average

Current conditions are compared to the long-term average conditions to put current conditions in perspective relative to average conditions. Long-term average conditions were calculated using a computer model simulation spanning 1985 through 2022. The below map shows the difference between current conditions and the long-term average conditions on the day noted. For more information on the long-term averages please see the Chesapeake Atlas.
