Rio Rancho Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Rio Rancho'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 Rio Rancho's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 15–May 6 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends October 21. Wherever the today marker sits, the nearest color change is your next appointment.
The Rio Rancho pool calendar
Opening — target April 22
Target April 22; the practical window runs April 15–May 6, and the 7-day mean crosses the 61°F threshold around May 6. Cold-water starts are the cheap ones.
Closing — deadline October 21
The window opens October 11 once water leaves the algae zone; the model deadline is October 21, a week ahead of the November 1 freeze normal.
Estimated water temperature by month
This is Rio Rancho'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 36° | 39° | 46° | 54° | 60° | 72° | 79° | 79° | 74° | 65° | 52° | 41° |
Warmest water typically July–August (peaking near 80°F); heaters and covers shift any month up.
