The Importance of Water Level and Evaporation in the Florida Heat

Family relaxing in a crystal-clear saltwater pool.

In Southwest Florida, where pools are used nearly every day, the intense sun and high humidity can wreak havoc on your water levels. During the summer, evaporation happens faster than many pool owners realize, leading to imbalanced chemistry, equipment damage, and unnecessary water waste.

 

Here’s what to know about evaporation and water levels—and simple ways to keep your pool running smoothly in the Florida heat. 💦 

 

🌞 How Florida Heat Impacts Your Pool’s Water Level 

In high heat, your pool loses water at an accelerated rate. On average, pools in Florida can lose ¼ inch of water per day during peak summer months. 

Main causes of water loss include: 

  • Evaporation from heat and wind 
  • Splash-out from frequent use 
  • Backwashing the filter 
  • Leaks (which are different from normal evaporation—more on that below!) 

✅ If left unchecked, low water levels can cause your pump to suck in air, which may damage the motor in a single speed pump, and disrupt water circulation.

⚖️ The Role of Proper Water Level in Pool Functionality 

Keeping your pool water at the right height—about halfway up the skimmer opening—is key for proper circulation, filtration, and chemical distribution. 

  • Too low, and your pump can run dry or burn out. 
  • Too high, and the skimmer won’t pull in debris properly, leading to extra surface debris. 

✅ Check your water level at least once per week, especially after heavy swimming or backwashing.

💦 Evaporation vs. Leaks: Know the Difference 

Sometimes, water loss is normal… and sometimes, it’s not. If you’re refilling your pool more than 2 inches per week, you may have a leak. 

✅  Try the bucket test: Fill a bucket with pool water and place it on a pool step, marking the water levels inside and outside the bucket. After 24–48 hours (with no rain or swimming), compare the two. If the pool water drops more than the bucket’s, you might have a leak and should consider a professional inspection.

🧠 Tips to Minimize Evaporation 

✅ Use a solar cover when the pool is not in use 

✅ Add a windbreak like a hedge or screen enclosure 

✅ Schedule swimming and refills in the early morning or late afternoon 

✅ Automate your water level with a leveler system to keep it stable year-round 

 

✨ Conclusion: Don’t Let Evaporation Drain Your Pool’s Performance! 

Hot Florida days can quickly drop your water level—but staying on top of it can save you from bigger problems down the line. By monitoring evaporation, checking levels twice a week, and knowing the difference between normal loss and leaks, you’ll protect your equipment and keep your pool running smoothly all summer.
