The bar compresses Panama City's whole pool year into one lane rope: gray floats for the off-season, hollow teal for the February 17–March 10 opening window, solid teal for swim weeks, hollow amber for the closing stretch that ends November 27. Wherever the today marker sits, the nearest color change is your next appointment.

Panama City pool season FAQ

When should I open my pool in Panama City, FL?

Open by February 24 — the model places Panama City's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Panama City opening guide has the 12-step sequence.

Close by November 27: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Panama City closing guide sequences the work backward from that date.

How long is the swim season in Panama City?

Panama City averages 185 days a year with normal highs of 80°F or better — about 31 days later than the Florida median. The Florida season index ranks all 64 covered cities by the same metric.

How warm does pool water get in Panama City?
