The lowest temperature at which clothes can dry outside depends on various factors, including humidity, wind, and the type of clothing material. Generally, clothes will dry more slowly in colder temperatures due to the reduced evaporation rate.
However, as long as the air is dry and there is enough airflow, clothes can still dry outside even in low temperatures. In freezing temperatures (0°C or 32°F), the drying process may be significantly slower, and items like thicker garments or items with high moisture content (such as jeans or towels) may take a longer time to dry compared to lighter fabrics.
It's worth noting that in extremely cold temperatures, clothes can freeze rather than dry, especially if the humidity is high. Freezing can make the drying process more difficult as the moisture in the clothes turns to ice. In such cases, it's advisable to bring the clothes indoors or use alternative drying methods such as using a clothes dryer or hanging them near a heat source.
Ultimately, the ability of clothes to dry outside in low temperatures will depend on the specific environmental conditions and the characteristics of the clothing items being dried.
