Finding the ideal temperature can depend on the season and the individuals involved. However, most people agree that the perfect temperature is between 100 and 102 degrees Fahrenheit. 

However, some like the water to be closer to body temperature at 98 degrees Fahrenheit, which is great for indoor hot tubs and many people from all walks of life. The maximum a hot tub should be set to is 104 degrees Fahrenheit and limited to 15 minutes at a time.

Another frequent approach from hot tub owners is changing the temperature based on the time of year, individual conditions, and ages.

The Perfect Hot Tub Temperature in Winter

For many hot tub owners, the temperature is often increased during the colder months. This gives a greater gap between the air temperature at 20 degrees Fahrenheit and the hot tub temperature at 104 degrees Fahrenheit.

This drastic change offers excellent muscle and body therapy in the colder months when things tend to get stiff.

Other people prefer a less drastic change, such as 20 degrees Fahrenheit ambient temperature to 101 degrees Fahrenheit in the hot tub. Neither option is incorrect; it just boils down to what each individual prefers when using their hot tub. 

The Perfect Hot Tub Temperature in Summer

If you live in an extremely hot climate where the summers can get rather warm, try dropping the temperature of your hot tub by a few degrees.

Many people in warmer climates tend to have their summer hot tubs in and around 98 degrees Fahrenheit. This can offer a refreshing soak and make your body feel more relaxed and cool. 

Children in Hot Tubs

If children use the hot tub, you want to ensure the temperature is around 95 degrees Fahrenheit or less. Kids overheat a lot faster than adults, and they don’t always recognize the signs or know to remove themselves from a situation, which can lead to dangerous situations and health risks. 

Seniors in Hot Tubs

People with health conditions or seniors should keep the hot tub at a lower temperature, closer to their body temperature, around 98 degrees Fahrenheit.

Older people and those with health conditions could be more severely affected by the increased temperature, with issues stemming from dehydration, health concerns, and blood pressure issues. 

It is also essential to stay hydrated while using the hot tub, so keeping water nearby is beneficial for the safety of the individual.

Pregnant People in Hot Tubs

If you are pregnant, it is probably best to avoid hot tubs in general. The increased temperatures can raise the core body temperature, which becomes a problem for the baby. Doctors recommend avoiding hot tubs entirely while pregnant. 

However, suppose you plan to use a hot tub anyway. In that case, it is best to keep the temperatures at an average body temperature of 101 degrees Fahrenheit or lower to lower the risk of fetal distress and death. This is especially important in the first 12 weeks of pregnancy when the percentage of having a miscarriage is incredibly high.
