Bend Pool Season: the Year on One Bar
Last updated: July 25, 2026 · dates · water temp
Bend'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.
Bend, OR — 60 swim days a yearEach dot on the bar is one week of Bend's typical year, colored by what the model says that week is for: gray weeks are off-season, hollow teal marks the opening window (June 7–June 28), solid teal is swim season, and hollow amber is the closing window ending September 13. The black marker is today — its position against the colors is the entire executive summary.
The Bend pool calendar
Opening — target June 14
Open by June 14 — a two-week head start on the June 28 crossing keeps startup chemistry small and beats the local service rush.
Closing — deadline September 13
The window opens September 6 once water leaves the algae zone; the model deadline is September 13, a week ahead of the September 20 freeze normal.
Estimated water temperature by month
Monthly averages of the site's water model run on Bend's own normals — the shape of a typical year, not a forecast. The widget above shows where the current year actually sits.
| Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|
| 32° | 34° | 37° | 42° | 48° | 55° | 63° | 67° | 62° | 54° | 43° | 34° |
The curve peaks near 68°F — comfortable-water months here usually involve a heater or a solar cover.
Every station tells its own story: compare this curve with Beaverton's pool season and Eugene's — neighboring normals stations can shift the windows by a week or more. The full ranking lives on the Oregon season index.
Bend pool season FAQ
When should I open my pool in Bend, OR?
Open by June 14 — the model places Bend's 61°F crossing about two weeks later, and every warm day you wait pushes the water toward the 65°F algae zone. The Bend opening guide has the 12-step sequence.
When should I close my pool in Bend?
Close by September 13: cool water keeps its winter chemistry, but freeze damage is the hard stop. The Bend closing guide sequences the work backward from that date.
How long is the swim season in Bend?
Bend averages 60 days a year with normal highs of 80°F or better — about 21 days later than the Oregon median. The Oregon season index ranks all 8 covered cities by the same metric.
How warm does pool water get in Bend?
An unheated pool near Bend typically peaks around 68°F in high summer and bottoms out near 32°F in winter, never quite reaching the 78°F comfort line without a heater or solar cover. The month-by-month curve above shows the whole cycle; the methodology page explains the ±5°F error bars.
