Last updated: July 25, 2026 · dates · water temp
El Paso'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.
El Paso, TX — 183 swim days a yearReading it takes ten seconds: 52 dots, one per week. Solid teal is El Paso's swim season; the hollow teal run before it (March 4 to March 25) is when to open; the hollow amber run after is when to close, with November 9 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The El Paso pool calendar
Opening — target March 11
Open by March 11 — a two-week head start on the March 25 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 9
Hold the cover until October 30, then winterize by November 9, a week ahead of the November 20 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on El Paso'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 46° | 49° | 55° | 63° | 71° | 81° | 85° | 84° | 80° | 72° | 60° | 49° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Edinburg's pool season and Flower Mound's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
