Finding the best hot tub temperature isn’t just about personal preference but also largely depends on the season. Outdoor temperature, weather conditions, and the way you use the hot tub will all affect the temperature at which you feel most comfortable, safest and most energy-efficient. Adjusting the temperature of your hot tub according to the season can maximize your experience.
In winter, most hot tub users prefer a higher water temperature, especially in cold regions. The generally recommended best hot tub temperature range is 100°F to 104° F. When the outdoor temperature is below freezing, a temperature range of 102°F to 104°F is particularly popular.
Warm water helps relieve muscle tension, promote blood circulation and reduce physical fatigue that is common in winter. It should be noted that the recommended maximum water temperature for healthy adults should not exceed 104°F, and the soaking time at the maximum temperature should be controlled at around 15 to 20 minutes to prevent the body from overheating.
Spring is the transitional season between winter and summer. As the temperature gradually rises, the water temperature of the hot tub also needs to be adjusted flexibly. Many users consider a temperature range of 98°F to 102°F to be relatively ideal.
Soaking at this temperature not only helps the body relax and relieve stress, but also avoids the stuffiness and discomfort caused by the rising environmental temperature. Setting the water temperature reasonably can ensure that the hot tub provides a good experience at different times of the day, finding the best balance between relaxation and comfort.

In summer, soaking in overly hot water in a high-temperature environment may make people feel uncomfortable. However, as long as the water temperature is properly adjusted, a hot tub can still offer you a comfortable experience. Many users set the water temperature within the range of 94°F to 98°F.
The lower water temperature not only allows people to enjoy the hot tub for a longer time, but is also suitable for entertainment, relaxation after work or cooling down at night. At the same time, appropriately lowering the water temperature can also reduce the risk of excessive sweating and dehydration, making summer hot spring soaking both comfortable and safe.
As the temperature gradually drops in autumn, it is necessary to appropriately increase the water temperature of the hot tub. Based on the coolness of the night, many users find that the temperature range of 98°F to 102°F is the most suitable. This temperature can provide a warm and comfortable soaking experience.
Autumn is usually regarded as one of the ideal seasons to enjoy a hot tub. The air is fresh, the climate is pleasant, and the water temperature is moderate. While enjoying the comfortable atmosphere brought by the seasonal changes, both the body and mind can be relaxed. Reasonable adjustment of water temperature can make the hot tub both safe and comfortable in autumn, fully exerting its effect of relaxing the body and mind and relieving fatigue.
Adjusting the water temperature of a hot tub according to the season can significantly enhance comfort, safety, and energy efficiency. The demand for ideal water temperature varies in different seasons. Following these seasonal suggestions can help you find the water temperature that suits you more easily. However, the best hot tub temperature should ultimately be determined based on individual comfort, health conditions, and usage habits.
