Farmington Hills Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
One bar, one year, one Farmington Hills 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.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Farmington Hills's swim season; the hollow teal run before it (May 5 to May 26) is when to open; the hollow amber run after is when to close, with September 29 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Farmington Hills pool calendar
Opening — target May 12
Open by May 12 — a two-week head start on the May 26 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline September 29
Hold the cover until September 19, then winterize by September 29, a week ahead of the October 17 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Farmington Hills'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 25° | 23° | 29° | 40° | 52° | 63° | 70° | 71° | 66° | 56° | 44° | 33° |
The curve peaks near 72°F — comfortable-water months here usually involve a heater or a solar cover.
