Hampton Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Hampton 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.
Hampton, VA — 102 swim days a yearEach dot on the bar is one week of Hampton'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 4–April 25), solid teal is swim season, and hollow amber is the closing window ending October 26. The black marker is today — its position against the colors is the entire executive summary.
The Hampton pool calendar
Opening — target April 11
Target April 11; the practical window runs April 4–April 25, and the 7-day mean crosses the 61°F threshold around April 25. Cold-water starts are the cheap ones.
Closing — deadline October 26
Hold the cover until October 16, then winterize by October 26, a week ahead of the November 15 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Hampton's typical-year water curve: the same EWMA model as the live widget, run on the 1991–2020 normals instead of this week's weather.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 42° | 41° | 46° | 54° | 63° | 72° | 78° | 79° | 76° | 67° | 56° | 47° |
Warmest water typically July–August (peaking near 79°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Fredericksburg's pool season and Lynchburg's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Virginia season index.
Hampton pool season FAQ
When should I open my pool in Hampton, VA?
Open by April 11 — the model places Hampton's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Hampton opening guide has the 12-step sequence.
When should I close my pool in Hampton?
Close by October 26: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Hampton closing guide sequences the work backward from that date.
How long is the swim season in Hampton?
Hampton averages 102 days a year with normal highs of 80°F or better — right on the statewide median. The Virginia season index ranks all 16 covered cities by the same metric.
