Norfolk Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
One bar, one year, one Norfolk 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.
Norfolk, VA — 105 swim days a yearEach dot on the bar is one week of Norfolk'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 31–April 21), solid teal is swim season, and hollow amber is the closing window ending October 28. The black marker is today — its position against the colors is the entire executive summary.
The Norfolk pool calendar
Opening — target April 7
Open by April 7 — a two-week head start on the April 21 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline October 28
The window opens October 18 once water leaves the algae zone; the model deadline is October 28, a week ahead of the November 16 freeze normal.
Estimated water temperature by month
This is Norfolk'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° | 55° | 64° | 71° | 78° | 79° | 75° | 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 Newport News's pool season and Portsmouth's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Virginia season index.
Norfolk pool season FAQ
When should I open my pool in Norfolk, VA?
Target April 7. That date backs off two weeks from the day Norfolk's 7-day mean temperature reaches 61°F, so you start up in cold, algae-resistant water. Work the full checklist in the Norfolk opening guide.
When should I close my pool in Norfolk?
The closing deadline is October 28 — late enough that the water has cooled out of the algae zone, early enough to beat Norfolk's first-freeze normal by about a week. See the Norfolk closing guide for the winterizing steps.
How long is the swim season in Norfolk?
Norfolk averages 105 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.
How warm does pool water get in Norfolk?
An unheated pool near Norfolk typically peaks around 79°F in high summer and bottoms out near 40°F in winter, spending roughly 2 months at or above the 78°F comfort line most swimmers prefer. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
