Florence Pool Season: the Year on One Bar
Last updated: July 25, 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.
Florence, AL — 134 swim days a yearEach 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.
Every station tells its own story: compare this curve with Dothan's pool season and Hoover's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Alabama season index.
Florence pool season FAQ
When should I open my pool in Florence, AL?
Open by April 4 — the model places Florence's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Florence opening guide has the 12-step sequence.
When should I close my pool in Florence?
Close by October 26: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Florence closing guide sequences the work backward from that date.
How long is the swim season in Florence?
Florence averages 134 days a year with normal highs of 80°F or better — about 12 days later than the Alabama median. The Alabama season index ranks all 10 covered cities by the same metric.
How warm does pool water get in Florence?
An unheated pool near Florence typically peaks around 79°F in high summer and bottoms out near 41°F in winter, spending roughly 1 month at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
