The Maryland, Delaware and Virginia months are the Chesapeake-region season. Everywhere else it is carried over by water temperature: a month counts at a spot when its usual water is in the range that marks the mid-Atlantic season (42–71°F), from the spot’s own gauge where it has one and an estimate from air temperature where it doesn’t. Each state lists the months that hold at half or more of its spots. Where the water temperatures come from.
