The bar compresses Lynchburg's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 18–May 9 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 13. Wherever the today marker sits, the nearest color change is your next appointment.

Lynchburg pool season FAQ

When should I close my pool in Lynchburg?

The closing deadline is October 13 — late enough that the water has cooled out of the algae zone, early enough to beat Lynchburg's first-freeze normal by about a week. See the Lynchburg closing guide for the winterizing steps.

How long is the swim season in Lynchburg?

Lynchburg averages 94 days a year with normal highs of 80°F or better — about 15 days later than the Virginia median. The Virginia season index ranks all 16 covered cities by the same metric.
