In the summer months most people don't want or need any pool heat. The pool will always feel cool at first but it is normally fine after a minute or two. You must be aware that even though the pool heaters are effective they will only heat to a certain amount above the air temperature.

In 2026, as in previous years, swimming pools in Florida generally do not need to be heated in June. During this month, Florida enters its tropical summer season, with daytime highs consistently reaching 30°C to 33°C (86°F–92°F) and high humidity. The intense solar radiation usually naturally warms unheated outdoor pools to a very comfortable 28°C to 30°C (82°F–86°F). Most residents and resorts turn off their electric heat pumps or gas heaters by late April or May. However, there are two exceptions: if the pool is heavily shaded by dense foliage or a "lanai" (screened enclosure) that blocks direct sunlight, it may feel a bit crisp in the early mornings. Additionally, people who use their pools for therapeutic purposes or low-impact water aerobics may still prefer a heater to maintain a consistent 32°C (90°F). For the average vacationer, the Florida sun provides more than enough heat in June to make the water feel like a "warm bath" without any mechanical assistance.
