St. Cloud Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of St. Cloud's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
St. Cloud, FL — 224 swim days a yearThe bar compresses St. Cloud's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 12–February 2 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 30. Wherever the today marker sits, the nearest color change is your next appointment.
The St. Cloud pool calendar
Opening — target January 19
Open by January 19 — a two-week head start on the February 2 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 30
The window opens December 25 once water leaves the algae zone; the model deadline is December 30, a week ahead of the January 6 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on St. Cloud's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 61° | 61° | 64° | 69° | 74° | 79° | 82° | 83° | 82° | 79° | 71° | 65° |
Warmest water typically June–October (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with St. Augustine's pool season and St. Petersburg's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.
St. Cloud pool season FAQ
When should I open my pool in St. Cloud, FL?
Target January 19. That date backs off two weeks from the day St. Cloud's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the St. Cloud opening guide.
When should I close my pool in St. Cloud?
The closing deadline is December 30 — late enough that the water has cooled out of the algae zone, early enough to beat St. Cloud's first-freeze normal by about a week. See the St. Cloud closing guide for the winterizing steps.
How long is the swim season in St. Cloud?
St. Cloud averages 224 days a year with normal highs of 80°F or better — about 5 days earlier than the Florida median. The Florida season index ranks all 64 covered cities by the same metric.
