Newport Beach Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Newport Beach pool. The season bar below draws everything the model knows — opening window, prime season, closing window — against today's date, with the working details one click away on the opening and closing pages.
The bar compresses Newport Beach's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the April 4–April 25 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 27. Wherever the today marker sits, the nearest color change is your next appointment.
The Newport Beach pool calendar
Opening — target April 11
Open by April 11 — a two-week head start on the April 25 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 27
Hold the cover until November 17, then winterize by November 27, a week ahead of the January 2 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Newport Beach'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 57° | 57° | 58° | 60° | 62° | 64° | 67° | 69° | 70° | 68° | 64° | 58° |
The curve peaks near 70°F — comfortable-water months here usually involve a heater or a solar cover.
