Brunswick Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Brunswick 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.
Brunswick, GA — 160 swim days a yearEach dot on the bar is one week of Brunswick'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 22–March 15), 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 Brunswick pool calendar
Opening — target March 1
Open by March 1 — a two-week head start on the March 15 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 25
The window opens November 15 once water leaves the algae zone; the model deadline is November 25, a week ahead of the December 25 freeze normal.
Estimated water temperature by month
This is Brunswick'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 53° | 54° | 59° | 65° | 72° | 78° | 82° | 83° | 80° | 75° | 65° | 58° |
Warmest water typically June–September (peaking near 83°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Augusta's pool season and Columbus's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
Brunswick pool season FAQ
When should I open my pool in Brunswick, GA?

When should I close my pool in Brunswick?
Winterize by November 25. The model holds the deadline a week ahead of Brunswick's NOAA 50% first-freeze date, so the plumbing is protected before the first hard night. The full sequence is in the Brunswick closing guide.
How long is the swim season in Brunswick?
Brunswick averages 160 days a year with normal highs of 80°F or better — about 27 days earlier than the Georgia median. The Georgia season index ranks all 18 covered cities by the same metric.
