Chesapeake Bay Environmental Forecast System

Use our forecasts and "nowcasts" 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.

Our Chesapeake Bay Environmental Forecast System simulates 3 conditions for each selected variable:

  1. Nowcast: present-day status of selected variable in Chesapeake Bay
  2. 2-Day Forecast: status of selected variable in the Bay 2 days from now, and
  3. Forecast Trend: difference between nowcast and forecast (% change over 2 days)
