For air temperatures from 80 to 90, a pool temperature of 80 is fine. Once is get above 90, you can let the pool temperature drop a little but not below 75.
Is 70 degree water too cold to swim in?
The National Center for Cold Water Safety states that swimmers entering water with a temperature below 70 degrees Fahrenheit should proceed with caution. … 65 to 70 degrees for a water temperature is often considered very cool. A pool water temperature range of 78 to 82 degrees is common and comfortable.
Can jumping into cold water kill you?

Your heart then has to work harder and your blood pressure increases. In the worst cases you could even have a heart attack.
Can you get hypothermia in 80 degree water?
How cold does the water have to be to put a person at risk for hypothermia? Even water temperatures as high as 75 and 80 degrees F (24 and 27 degrees C) can be dangerous, but it would most likely take much longer than 15 minutes to become debilitated.
Is 16 degrees too cold to swim?
However, the research concluded that: “For lean, elite level swimmers, 16°C and 18°C will cause hypothermia in under two hours. For a shorter swim, 16°C is possible. Swimmers are likely to be coolest some time after exiting the water.” … The current minimum water temperature for FINA sanctioned races is 16 degrees.
What temperature of water is too cold to swim in?

The only thing warming the water is the physical agitation caused by the swimming. … All the energy that goes into the water stays there. None goes into the air above or the material surrounding the pool.
How much heat does a pool lose overnight?
A pool that is uncovered can lose up to 5 degrees F overnight; a good cover can cut that loss by half. Used at night or whenever your pool is not in use, the pool cover can help save fuel costs by cutting heat loss regardless of the type of heating you utilize.
