Adjust a baseline evaporation estimate for wind exposure.
Enter realistic measurements, observed conditions, or documented equipment information. Review the result as a planning estimate and adjust assumptions to understand what drives it.
Weather, site conditions, equipment, testing, and actual water measurements can change the result. Use local observations whenever possible.
Confirm units before calculating. Record dates, weather, meter readings, equipment settings, photographs, and product labels when they affect the decision. A single estimate is less useful than a repeatable baseline.
Follow manufacturer instructions, current product markings, local codes, and official emergency guidance. Consult a qualified pool professional when structure, electricity, gas, suction entrapment, diving, flooding, or severe weather is involved.
