Florence Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Florence 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 Florence's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 28–April 18), solid teal is swim season, and hollow amber is the closing window ending October 26. The black marker is today — its position against the colors is the entire executive summary.
The Florence pool calendar
Opening — target April 4
Open by April 4 — a two-week head start on the April 18 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 26
The window opens October 16 once water leaves the algae zone; the model deadline is October 26, a week ahead of the November 3 freeze normal.
Estimated water temperature by month
This is Florence'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.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 42° | 49° | 57° | 65° | 73° | 78° | 79° | 76° | 67° | 55° | 47° |
Warmest water typically July–August (peaking near 79°F); heaters and covers shift any month up.
