Salt Lake City Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Salt Lake City 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.
Each dot on the bar is one week of Salt Lake City's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (April 22–May 13), solid teal is swim season, and hollow amber is the closing window ending October 14. The black marker is today — its position against the colors is the entire executive summary.
The Salt Lake City pool calendar
Opening — target April 29
Target April 29; the practical window runs April 22–May 13, and the 7-day mean crosses the 61°F threshold around May 13. Cold-water starts are the cheap ones.
Closing — deadline October 14
Hold the cover until October 4, then winterize by October 14, a week ahead of the November 8 freeze normal. Late and cold beats early and warm.
