Athens Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Athens's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Athens, GA — 148 swim days a yearEach dot on the bar is one week of Athens'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 21–April 11), solid teal is swim season, and hollow amber is the closing window ending November 1. The black marker is today — its position against the colors is the entire executive summary.
The Athens pool calendar
Opening — target March 28
Open by March 28 — a two-week head start on the April 11 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 1
The window opens October 22 once water leaves the algae zone; the model deadline is November 1, a week ahead of the November 10 freeze normal.
Estimated water temperature by month
This is Athens'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 45° | 46° | 52° | 59° | 67° | 75° | 80° | 81° | 77° | 69° | 58° | 49° |
Warmest water typically July–August (peaking near 81°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Alpharetta's pool season and Atlanta's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Georgia season index.
Athens pool season FAQ
When should I open my pool in Athens, GA?
Open by March 28 — the model places Athens's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Athens opening guide has the 12-step sequence.
When should I close my pool in Athens?
Close by November 1: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Athens closing guide sequences the work backward from that date.
How long is the swim season in Athens?
Athens averages 148 days a year with normal highs of 80°F or better — right on the statewide median. The Georgia season index ranks all 18 covered cities by the same metric.
How warm does pool water get in Athens?
An unheated pool near Athens typically peaks around 81°F in high summer and bottoms out near 44°F in winter, spending roughly 2 months 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.
