Each dot on the bar is one week of High Point's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 24–April 14), solid teal is swim season, and hollow amber is the closing window ending October 28. The black marker is today — its position against the colors is the entire executive summary.
