Bakersfield Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
This is the one-page view of Bakersfield'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.
Each dot on the bar is one week of Bakersfield's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (March 23–April 13), solid teal is swim season, and hollow amber is the closing window ending November 10. The black marker is today — its position against the colors is the entire executive summary.
The Bakersfield pool calendar
Opening — target March 30
Target March 30; the practical window runs March 23–April 13, and the 7-day mean crosses the 61°F threshold around April 13. Cold-water starts are the cheap ones.
Closing — deadline November 10
The window opens October 31 once water leaves the algae zone; the model deadline is November 10, a week ahead of the December 8 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Bakersfield'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° | 50° | 55° | 59° | 66° | 74° | 82° | 83° | 80° | 72° | 61° | 51° |
Warmest water typically July–September (peaking near 84°F); heaters and covers shift any month up.
