Summer is the perfect time to swim. The forecast calls for hot weather and the kids are out of school making it great time to gather and cool off in the water. However, the warmer temperatures do take some consideration when it comes to pool care. Read on to learn how hot weather affects your pool and how to stay on top of it for clear water all season long.

Chemical Use & Consumption

The warmer the water, the more demand on your chemicals, especially chlorine. Chlorine is susceptible to the sun’s UV rays. It can break down if your stabilizer is low. Warm water can also make your chlorine less effective. Additionally, algae, bacteria and other microorganisms can thrive in warm water environments. These nuisances love the heat, and summer storms bring food for algae as well. Luckily, All In One Algaecide is the perfect defense against blooms. Run your pump from sunrise to sunset to keep the water in circulation and reduce the potential for algae growth. The additional run time allows the water to be filtered more frequently.

To keep your pool in top shape all summer, chlorine should be kept at 2-4 ppm throughout the year, and the pool needs to be shocked on a weekly basis. During especially hot months, when the pool temperature is above 85°, additional sanitizers and shock may be necessary. Consider adding an additional tablet to your chlorinator or increasing the output on your Salt Chlorine Generator. You may need to shock your pool more if algae is present. Talk to a professional at your local Pinch A Penny for help.


If the weather is especially hot it can cause excessive evaporation. When your pool loses water this way, it also takes some of the chemicals in your pool with it. Chlorine levels can get too high, so make sure to test your water often to keep the chemicals balanced. You can also use Suncoast Metal Control to keep metals at bay when you add water to the pool.

Scaling and Pool Equipment

At higher temperatures, there is also an increased tendency for scaling conditions. These scale build-ups are similar to high pH, Alkalinity and Calcium levels. This can cause damage to your pool’s plumbing and equipment, including pumps and automatic pool cleaners. It will also cause build-up on your pool’s walls and surfaces.

Comfort and Enjoyment

If your pool water is getting too warm, it may not be comfortable to swim in either. Consider buying a pool chiller to lower the temperature of the water in your pool. This means a more refreshing dip when the temperatures go up!
