Be skeptical of "year-round outdoor pools" in Arizona.

First, I am aware that AZ is a hot state and most of the year, an unheated outdoor pool will feel great. But if you are traveling in the winter and would like some pool time, I would recommend being very skeptical of any hotel's claim that their pool is for year-round use. Just because a pool is heated doesn't mean it's comfortable or even safe to use in cold temperatures. We have run into this twice on our trip here.

Arizona is known for its hot summers, so the concept of a “year-round outdoor pool” is often marketed without much clarification. While most unheated pools are very comfortable during the spring, summer, and early fall, winter temperatures can make even heated pools less inviting than expected.

Key points to consider when evaluating “year-round” pools:

  • Heating level matters: Some pools are technically heated but not to a temperature that is comfortable for swimming in cooler months. A pool might be heated to 78°F (25°C), which can feel chilly in December or January.
  • Air temperature: Even if the water is heated, outdoor air temperatures in winter (often 40–60°F / 4–16°C in many parts of Arizona) can make entering and exiting the pool uncomfortable or even unsafe.
  • Wind and exposure: Pools exposed to wind or shaded areas can feel significantly colder, reducing the “year-round” usability.

Tips to avoid disappointment:

  • Contact the hotel directly and ask the exact water temperature during the winter months.
  • Ask if there are indoor heated pools as a backup option if the outdoor pool is too cold.
  • Check recent guest reviews for winter months—real experiences often highlight if the pool is usable in colder weather.
  • Consider resort spas or hot tubs, which are usually heated to a more comfortable level for year-round enjoyment.

In summary, while outdoor pools in Arizona are fantastic for most of the year, winter travelers should be skeptical of “year-round” claims. It’s best to verify the water temperature, consider air conditions, and have indoor or hot tub options in mind to ensure a pleasant swimming experience.
