Season geography

Across Virginia's featured cities, typical openings spread from May 9 to May 12, closings from Sep 28 to Oct 6, and the unheated season runs 140–147 days depending on where you are. Elevation, coastal water, and urban heat all pull real dates around, which is exactly why a state-level answer isn't enough.

For your exact town, the pool season lookup takes a ZIP code. Opening day itself is a chemistry job — the dosing calculator turns your first test reading of the year into exact amounts.
