Use our forecasts of temperature, salinity, dissolved oxygen, and other physical and chemical factors within the Chesapeake Bay to help monitor Bay health and plan your on-the-water activities. Based on observations and computer models developed by the Virginia Institute of Marine Science and partners, these tools accurately predict the current status of important environmental variables and how they are likely to change in the short-term. They also compare how conditions today are to the historical average, to put this year into perspective with past years.

Our Chesapeake Bay Environmental Forecast System simulates 5 conditions for many selected variables:

1. Today's Forecast: present-day status of selected variable in Chesapeake Bay
2. 2-Day Forecast: status of selected variable in the Bay for tomorrow, and
3. 5-Day Forecast: status of selected variable for 5-day forecast, and
4. Forecast Trend: difference between today's forecast and 5-day forecast (change over 5 days)
5. Comparison to Historical: Difference from the historical average conditions today
