The bar compresses Panama City's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 17–March 10 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 27. Wherever the today marker sits, the nearest color change is your next appointment.
