Mesquite Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Mesquite'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.
Each dot on the bar is one week of Mesquite'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 9–March 30), solid teal is swim season, and hollow amber is the closing window ending November 10. The black marker is today — its position against the colors is the entire executive summary.
The Mesquite pool calendar
Opening — target March 16
Open by March 16 — a two-week head start on the March 30 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 10
Hold the cover until October 31, then winterize by November 10, a week ahead of the November 19 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Mesquite'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 46° | 48° | 54° | 62° | 69° | 78° | 83° | 86° | 82° | 73° | 61° | 51° |
Warmest water typically June–September (peaking near 86°F); heaters and covers shift any month up.
