Reading it takes ten seconds: 52 dots, one per week. Solid teal is Poinciana's swim season; the hollow teal run before it (January 12 to February 2) is when to open; the hollow amber run after is when to close, with December 30 as the deadline; gray is the covered season. Today's marker shows where you stand in that cycle right now.

Every station tells its own story: compare this curve with Plantation's pool season and Pompano Beach's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Florida season index.

Poinciana pool season FAQ

When should I open my pool in Poinciana, FL?

Open by January 19 — the model places Poinciana's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Poinciana opening guide has the 12-step sequence.

When should I close my pool in Poinciana?

Close by December 30: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Poinciana closing guide sequences the work backward from that date.

How long is the swim season in Poinciana?

Poinciana averages 224 days a year with normal highs of 80°F or better — about 5 days earlier than the Florida median. The Florida season index ranks all 64 covered cities by the same metric.

How warm does pool water get in Poinciana?

An unheated pool near Poinciana typically peaks around 83°F in high summer and bottoms out near 60°F in winter, spending roughly 5 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.
