Edinburg Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Edinburg'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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Edinburg's swim season; the hollow teal run before it (January 9 to January 30) is when to open; the hollow amber run after is when to close, with December 26 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Edinburg pool calendar
Opening — target January 16
Open by January 16 — a two-week head start on the January 30 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 26
The window opens December 20 once water leaves the algae zone; the model deadline is December 26, a week ahead of the January 2 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Edinburg's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 60° | 62° | 67° | 72° | 79° | 84° | 86° | 87° | 85° | 81° | 73° | 65° |
Warmest water typically May–October (peaking near 87°F); heaters and covers shift any month up.
