Paradise Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Paradise'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.
Paradise, NV — 180 swim days a yearEach dot on the bar is one week of Paradise's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (February 24–March 17), solid teal is swim season, and hollow amber is the closing window ending November 16. The black marker is today — its position against the colors is the entire executive summary.
The Paradise pool calendar
Opening — target March 3
Open by March 3 — a two-week head start on the March 17 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 16
Hold the cover until November 6, then winterize by November 16, a week ahead of the December 15 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Paradise'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 48° | 51° | 57° | 65° | 73° | 83° | 91° | 93° | 88° | 77° | 63° | 51° |
Warmest water typically June–September (peaking near 94°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with North Las Vegas's pool season and Reno's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Nevada season index.
