Last updated: July 15, 2026 · dates · water temp

Each dot on the bar is one week of Memphis'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 18–April 8), solid teal is swim season, and hollow amber is the closing window ending November 3. The black marker is today — its position against the colors is the entire executive summary.
