Corpus Christi Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
This is the one-page view of Corpus Christi's pool year: both model windows, the estimated water-temperature curve, and today's live position on the season bar. The detailed checklists live on the opening and closing guides; this page is the calendar you check between them.
Corpus Christi, TX — 214 swim days a yearEach dot on the bar is one week of Corpus Christi's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (January 20–February 10), solid teal is swim season, and hollow amber is the closing window ending December 19. The black marker is today — its position against the colors is the entire executive summary.
The Corpus Christi pool calendar
Opening — target January 27
Target January 27; the practical window runs January 20–February 10, and the 7-day mean crosses the 61°F threshold around February 10. Cold-water starts are the cheap ones.
Closing — deadline December 19
Hold the cover until December 9, then winterize by December 19, a week ahead of the December 30 freeze normal. Late and cold beats early and warm.
Estimated water temperature by month
This is Corpus Christi'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 |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 58° | 60° | 65° | 71° | 77° | 83° | 86° | 87° | 85° | 80° | 71° | 63° |
Warmest water typically June–October (peaking near 87°F); heaters and covers shift any month up.
Every station tells its own story: compare this curve with Conroe's pool season and Dallas's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Texas season index.
