The answer comes from an hourly forecast for your location. We estimate how fast water leaves wet fabric using temperature, relative humidity, wind speed and how much sun is reaching the ground, then add up those hourly drying rates until the load would be dry.
Then we check the timing: if rain is forecast before the load finishes drying, the answer becomes no, or wait for a better window later today. Heavier items are given more water to lose, so towels and jeans need a longer stretch of good weather than a shirt.
+Can clothes dry outside when it's cold?
Yes, as long as the air is dry and moving. Cold air holds less moisture, so drying is slower, but a crisp windy winter day can dry a load faster than a warm, still, humid one.
+Does wind help clothes dry faster?
A lot. Wind removes the saturated layer of air sitting against the fabric and replaces it with drier air, which is often the single biggest factor after humidity.
+Can clothes dry outside when it's cloudy?
Yes. Sunshine speeds things up, but drying is really driven by humidity and wind, so a breezy overcast day with dry air still works.
+Does humidity affect drying time?
It's decisive. When the air is already near saturation there is nowhere for the water to go, so laundry can stay damp for hours no matter how warm it is.
