Yuma Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Yuma'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.
The bar compresses Yuma's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the January 19–February 9 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends December 7. Wherever the today marker sits, the nearest color change is your next appointment.
The Yuma pool calendar
Opening — target January 26
Open by January 26 — a two-week head start on the February 9 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline December 7
The window opens November 27 once water leaves the algae zone; the model deadline is December 7, a week ahead of the December 28 freeze normal.
Estimated water temperature by month
This is Yuma'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 58° | 60° | 65° | 71° | 77° | 85° | 93° | 95° | 93° | 84° | 72° | 60° |
Warmest water typically June–October (peaking near 95°F); heaters and covers shift any month up.
