Longview Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
Longview's whole pool calendar, condensed: when the water warms, when it cools, and where today falls between those edges. Use the opening guide and closing guide for the step-by-step work; keep this page for the dates.
Reading it takes ten seconds: 52 dots, one per week. Solid teal is Longview's swim season; the hollow teal run before it (March 5 to March 26) is when to open; the hollow amber run after is when to close, with November 13 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.
The Longview pool calendar
Opening — target March 12
Open by March 12 — a two-week head start on the March 26 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline November 13
Hold the cover until November 3, then winterize by November 13, a week ahead of the November 23 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
Monthly averages of the site's water model run on Longview'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 47° | 49° | 55° | 63° | 70° | 79° | 83° | 85° | 82° | 73° | 62° | 52° |
Warmest water typically June–September (peaking near 85°F); heaters and covers shift any month up.
