Each dot on the bar is one week of Hampton's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 4–April 25), solid teal is swim season, and hollow amber is the closing window ending October 26. The black marker is today — its position against the colors is the entire executive summary.
