Calculate how long your clothes will take to dry outside using real physics. Adjust for temperature, humidity, wind speed, and fabric type to get an accurate drying time estimate.
Use our physics-based calculator to estimate outdoor drying times for t-shirts, jeans, towels, hoodies, bedding, and delicates. Adjust temperature, humidity, and wind speed to see how weather conditions affect drying time.
The calculator uses the principles of evaporation physics to estimate how long your laundry will take to dry outdoors. Higher temperatures and wind speeds increase evaporation rate, while higher humidity slows it down. Each fabric type has a different moisture retention multiplier that affects total drying time.
