Gainesville Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Gainesville pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
Each dot on the bar is one week of Gainesville's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 12–March 5), solid teal is swim season, and hollow amber is the closing window ending November 25. The black marker is today — its position against the colors is the entire executive summary.
The Gainesville pool calendar
Opening — target February 19
Target February 19; the practical window runs February 12–March 5, and the 7-day mean crosses the 61°F threshold around March 5. Cold-water starts are the cheap ones.
Closing — deadline November 25
Hold the cover until November 23, then winterize by November 25, a week ahead of the December 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Gainesville's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
