Swimming Pool Evaporation Calculator
Is your pool losing water faster than normal? Before calling a leak detection specialist, it’s important to understand how much water your pool naturally loses every day through evaporation — and how much might actually be a leak. Use our free Swimming Pool Evaporation Calculator below to get an instant estimate of your pool’s expected daily water loss based on real-time local weather conditions, your water temperature, and pool size.
💧 Jump to the Calculator ↓Is My Pool Leaking or Just Evaporating?
This is one of the most common questions pool owners face. Every pool loses water every single day — but evaporation and leaks behave very differently. Normal pool evaporation typically ranges from 1/4 inch to 1 inch per day depending on temperature, humidity, wind, and sun exposure. If your pool is losing significantly more than that, you may have an active leak that needs professional attention. Our calculator uses real-time weather data combined with industry-standard evaporation formulas to estimate your pool’s natural daily water loss — and flags potential leak loss automatically.
How To Use This Calculator
- Enter your pool’s ZIP code — we’ll pull live local weather conditions automatically
- Enter your current water temperature in °F
- Enter your pool’s surface area in square feet (length × width for a rectangular pool)
- Optionally enter your observed daily water loss to compare against expected evaporation
- Hit Calculate — results appear instantly, including a potential leak estimate if applicable
- Adjust wind speed manually if conditions at your pool differ from the weather station
- Export your results to PDF for your records
What Factors Affect Pool Evaporation?
Several variables affect how much water your pool loses to evaporation each day:
💧 Water Temperature
Warmer water evaporates faster. A pool heated to 85°F will lose significantly more water than one sitting at 70°F.
🌡 Air Temperature and Humidity
Hot, dry days accelerate evaporation. High humidity slows it down considerably — which is why humid Southeast summers can behave differently than you’d expect.
💨 Wind Speed
Wind is one of the biggest drivers of pool evaporation. Even a light breeze across the water surface dramatically increases daily water loss — which is why our calculator lets you adjust wind speed manually.
📐 Pool Surface Area
A larger pool has more exposed surface, meaning more evaporation. A small plunge pool behaves very differently than a large rectangular pool or freeform design.
☀️ Sun Exposure
Direct sunlight heats both the water and surrounding air, compounding evaporation effects throughout the day. Shaded pools evaporate noticeably less.
When To Call a Pool Leak Detection Specialist
If your pool is consistently losing more water than this calculator estimates for evaporation, it’s time to investigate further. Common signs of an active pool leak include:
- Water loss exceeding 1 inch per day after accounting for evaporation
- Wet spots or soggy ground around the pool deck or equipment pad
- Needing to add water more than twice per week
- Unexplained increases in your water or chemical bills
- Air in the pump or pressure loss in the return lines
- Visible cracks in the shell, tile line, or coping
