Goodyear Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Goodyear's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Goodyear, AZ — 231 swim days a yearThe bar compresses Goodyear's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 9–March 2 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 30. Wherever the today marker sits, the nearest color change is your next appointment.
The Goodyear pool calendar
Opening — target February 16
Target February 16; the practical window runs February 9–March 2, and the 7-day mean crosses the 61°F threshold around March 2. Cold-water starts are the cheap ones.
Closing — deadline November 30
Hold the cover until November 20, then winterize by November 30, a week ahead of the December 22 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Goodyear'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 54° | 56° | 61° | 68° | 76° | 86° | 93° | 94° | 91° | 81° | 69° | 57° |
Warmest water typically June–October (peaking near 94°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Glendale's pool season and Maricopa's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Arizona season index.
Goodyear pool season FAQ
When should I open my pool in Goodyear, AZ?
Target February 16. That date backs off two weeks from the day Goodyear's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Goodyear opening guide.
When should I close my pool in Goodyear?
The closing deadline is November 30 — late enough that the water has cooled out of the algae zone, early enough to beat Goodyear's first-freeze normal by about a week. See the Goodyear closing guide for the winterizing steps.

Goodyear averages 231 days a year with normal highs of 80°F or better — about 9 days earlier than the Arizona median. The Arizona season index ranks all 20 covered cities by the same metric.
