How is it calculated?

We look at the hourly forecast from Open-Meteo for your city and work out how much your laundry dries each hour.

• If it rains (or the chance of rain is 50% or more) that hour doesn't count.
• Higher temperature and more wind dry faster; more humidity dries slower.
• At night laundry dries more slowly (no sun), so those hours count for less.
• We say Yes if, from now, there are enough drying hours (the equivalent of 10 good hours) before it rains.
• If we say No, we tell you the next window when there's enough time.
