Season geography

Across New Mexico's featured cities, typical openings spread from Apr 25 to Jun 8, closings from Sep 1 to Oct 13, and the unheated season runs 85–170 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.
