Miami Pool Season: the Year on One Bar

Last updated: July 15, 2026 · dates · water temp

Miami 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.

Each dot is one week of Miami'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 67°F to 83°F, and the today marker tells you where in that cycle you're standing. Maintenance follows the same curve — heavier through the 203-day prime stretch, lighter but never zero through winter.
