Here, the maps show warmer than average water temperatures from January through March 2020, cooler than average from April through June, near average July through September, and slightly warmer than average October through December. The long-term baseline is from the years 2008-2019.]](https://essic.umd.edu/wp-content/uploads/2025/09/rv-chesapeake2-150x150.jpg)
