Many people assume that once winter arrives, the outdoor clothesline has to be abandoned in favour of a tumble dryer. The good news is that this isn't true. Even on cold winter days, clothes can dry perfectly well outside under the right conditions.
In fact, line drying during winter can save on electricity costs, reduce wear on your clothes and leave your laundry smelling fresh. The secret is understanding how weather conditions affect drying and making the most of the daylight hours.
Yes, clothes can dry outside in winter
Temperature isn't the only factor that determines how quickly clothes dry. Water evaporates whenever the surrounding air can absorb moisture, even if it's cold.
A cool, sunny winter's day with low humidity and a light breeze can dry clothes effectively, sometimes moreso than a warm but humid day with little airflow.
With the right conditions, your washing can dry surprisingly well outdoors throughout winter, helping you save energy while avoiding unnecessary use of the tumble dryer.
Wind is often more important than temperature
One of the biggest factors in drying clothes is airflow. As wind passes over damp fabric, it carries away moisture, allowing more water to evaporate.
That's why washing often dries surprisingly quickly on cool, breezy days.
To make the most of windy conditions:
- Position your clothesline where it receives good airflow.
- Leave space between garments so air can circulate freely.
- Hang larger items such as towels and sheets fully open rather than folded.
- Avoid overcrowding the line, as tightly packed clothing traps moisture.
Humidity slows the drying process
Humidity refers to the amount of moisture already in the air. When humidity is high, the air can't absorb as much water from your washing, so clothes take longer to dry.
Winter often brings mist, drizzle and damp weather, all of which increase humidity and slow down evaporation.
If the weather is cold but dry with a light breeze, outdoor drying can still work well. However, on damp, or misty days with high humidity, it's usually better to dry your clothes indoors on an airing rack in a well-ventilated room, or use a tumble dryer if available.
What about frosty mornings?
A frosty morning doesn't necessarily mean you can't use your clothesline.
If clothes are hung out while temperatures are below freezing, the moisture in the fabric may freeze before it evaporates. But once temperatures rise later in the day, the ice melts and drying begins.
For the quickest results, though, it's usually better to wait until the morning frost has cleared before hanging out your washing.
Timing makes a big difference
Winter days are shorter, so try to get your washing onto the line as early as possible.
Late morning is often the ideal time once any overnight frost or fog has disappeared. This gives your clothes the maximum amount of daylight and the warmest part of the day to dry.
Avoid hanging washing late in the afternoon, as dropping temperatures and rising humidity can significantly slow the drying process.
Tips for drying clothes faster in winter
A few simple habits can help your washing dry more efficiently during the colder months:
- Use your washing machine's highest suitable spin speed to remove as much water as possible.
- Shake out each garment before hanging it up to improve airflow and reduce creases.
- Leave gaps between items instead of hanging everything tightly together.
- Hang towels, sheets and other large items fully open whenever possible.
- Take advantage of breezy days, even if they feel cold.
- If clothes are still slightly damp by sunset, bring them inside to finish drying.
Should you leave clothes outside overnight?
It's generally best to avoid leaving washing on the clothesline overnight during winter.
Even if your clothes are almost dry, overnight dew, higher humidity and cooler temperatures can leave them feeling damp again by morning. In many parts of New Zealand, frost can also settle on your washing overnight.
If your laundry hasn't fully dried before sunset, bringing it indoors is usually the quickest way to finish the job.
