Last updated: July 25, 2026 · dates · water temp
No opening date, no closing deadline: Deerfield Beach's season bar below is one long swim window with a comfort gradient. The spring refresh and winter care pages hold the practical checklists for a pool that never sleeps; this page is the dashboard that says which of them applies today.
Deerfield Beach, FL — 258 swim days a yearEach dot is one week of Deerfield Beach's year, and here they're all solid teal — the model finds no off-season to draw. What varies instead is comfort: the water table below shows the seasonal range from 68°F to 84°F, and the today marker tells you where in that cycle you're standing. Maintenance follows the same curve — heavier through the 258-day prime stretch, lighter but never zero through winter.
