Wind Effect on Pool Evaporation Calculator
Calculate how much wind increases your pool's water loss. See the impact of wind speed on evaporation rates and thermal energy loss.
Why Wind Drains Pools
Evaporation happens when the air immediately above the water becomes saturated with moisture. In still air, this layer of "heavy" air sits on the surface and slows further evaporation. Wind physically blows this layer away, replacing it with dry air that can absorb more waterΠ²Πβcreating a continuous cycle of moisture loss.
Pro Tip: Even a light 5mph breeze can double the evaporation rate compared to perfectly still air. Wind blocks or "privacy screens" can significantly reduce water loss.
Frequently Asked Questions
Does wind change the chemicals?
Wind itself doesn't eat chemicals, but the increased evaporation leaves behind minerals (calcium, salt), making your water "harder" over time. Also, wind-blown debris can consume chlorine.
Can I stop wind with a fence?
Yes! Solid fences or hedge rows can create a "boundary layer" of still air over the pool if they are taller than the pool surface, even if they are several feet away.
