Corpus Christi Pool Season: the Year on One Bar
Last updated: July 15, 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.
Each 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.
