The bar compresses Leesburg's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 14–February 4 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 31. Wherever the today marker sits, the nearest color change is your next appointment.

Leesburg pool season FAQ

Close by December 31: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Leesburg closing guide sequences the work backward from that date.
