Can you dry clothes outside in winter?
Yes, and often better than people expect. Cold air holds less moisture, so a crisp, bright, breezy winter day can dry a wash beautifully. The days to avoid are the mild, damp, still ones, not the cold ones.
Cold and dry beats mild and damp
Winter gets written off because people assume warmth is what dries washing. It is not, and cold air has a real advantage: it holds far less water, so on a clear crisp day the humidity is genuinely low and the air is thirsty.
A bright, still-frosted January morning with a light wind is a proper drying day. A grey, mild, drizzly one at the same temperature is not. The temperature on the thermometer tells you almost nothing on its own.
What freezing actually does
In a hard frost, washing freezes stiff on the line and then freeze-dries. The ice turns straight to vapour without melting first, and lifts the moisture out of the fabric as it goes. Clothes come in board-stiff and close to dry, and soften as soon as they warm up indoors.
It looks alarming the first time. It works.
The two winter traps
The first is daylight. You have maybe eight usable hours, and the drying rate collapses in the last two as the temperature falls. Get washing out by nine and in by three. A load that was nearly dry at three can be damper at five than it was at midday, because dew and frost settle back onto the fabric.
The second is mild wet weather. Around 8 to 12°C with drizzle and no wind, the air is already brimming and nothing will dry. Those days feel more promising than a hard frost and are far worse.
