Last updated: July 25, 2026 · dates · water temp
Hialeah runs a twelve-month pool calendar — the model finds no week cold enough to force a closing. This page tracks the water-temperature curve and the prime-season stretch; the spring refresh and winter care guides cover the routines that replace opening and closing here. Keep it bookmarked as the between-guides dashboard for the year.
