North Richland Hills Pool Season: the Year on One Bar
Last updated: July 15, 2026 · dates · water temp
North Richland Hills'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.
The bar compresses North Richland Hills's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the March 10–March 31 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 9. Wherever the today marker sits, the nearest color change is your next appointment.
The North Richland Hills pool calendar
Opening — target March 17
Target March 17; the practical window runs March 10–March 31, and the 7-day mean crosses the 61°F threshold around March 31. Cold-water starts are the cheap ones.
Closing — deadline November 9
The window opens October 30 once water leaves the algae zone; the model deadline is November 9, a week ahead of the November 20 freeze normal.
