Drying laundry outside is often the cheapest and nicest way to get your washing fresh and dry. Whether you want to know if your laundry can dry outside today, how long drying laundry outside takes or at what humidity it makes sense: in the right conditions, your laundry dries faster than many people think.
When is the best time to dry laundry outside?
The best conditions for drying laundry outside are a combination of dry air, some wind and enough daytime hours. Many people mainly look at temperature or sunshine, but humidity is at least as important. On a clear, breezy spring day, your laundry can dry faster than on a warm, muggy summer day.
Want to judge whether your laundry will dry outside today? Then look at these four factors:
- low humidity
- a little wind or air circulation
- no rain or fog
- enough hours of daylight before the evening humidity rises
The morning and early afternoon are usually the best time. That way you benefit from rising temperatures and the dew burning off. Leaving laundry outside to dry overnight is usually less smart, because the air gets more humid and the drying process slows down considerably.
Which weather conditions are ideal?
Temperature
A higher temperature helps, but it isn’t decisive. Drying laundry outside at 10°C works fine, and drying laundry outside at 15°C often goes well too, as long as the air is dry and there’s some wind. Warm weather speeds up evaporation, but without dry air, heat on its own does less than you might expect.
Humidity
Humidity determines how much moisture the outside air can still absorb. The lower it is, the faster your laundry dries. If you’re wondering what humidity is suitable for drying laundry outside, a good rule of thumb is that anything below about 60% is favorable. Between 60% and 75% it still works, but it takes longer. Above 75%, laundry often dries slowly, especially without wind or sun.
That’s why humidity matters so much when you dry laundry outside: it’s not the thermometer, but the combination of air and movement that makes the difference.
Wind
Wind carries moisture straight away from the fabric. That makes laundry dry faster outside, even in cloudy weather. A light breeze is already enough to noticeably speed up drying. So on a cloudy but windy day, your laundry can dry faster than on a sunny, still day.
Sun and shade
The sun warms the fabric and helps it dry, but full sun isn’t always necessary. Laundry also dries well in light shade with enough wind. Dark clothing can heat up faster in bright sun, while light and delicate fabrics can actually fade faster. White laundry sometimes ends up stiffer or slightly yellowish if it hangs in strong sun for too long. Struggling with sweat or yellow stains? Then take a look at yellow stains on white clothing.
How long does laundry take to dry outside?
How long does laundry take to dry outside? That depends on the type of textile, the thickness of the fabric, how well you spun it and of course the weather. Thin garments are often dry within a few hours, while towels, jeans and bed linen need longer.
As a practical guideline, you can use this:
| Item | Good drying weather | Less favorable drying weather |
|---|---|---|
| T-shirts and light underwear | 1 to 3 hours | 3 to 6 hours |
| Shirts and blouses | 2 to 4 hours | 4 to 7 hours |
| Towels | 3 to 5 hours | 5 to 8 hours |
| Jeans | 4 to 6 hours | 6 to 10 hours |
| Bed linen | 3 to 6 hours | 6 to 9 hours |
Wondering how quickly laundry dries outside? On a dry, sunny and slightly windy day, light laundry can be dry in just 1 to 2 hours. With higher humidity or little wind, that quickly goes up.
Will the laundry dry outside today?
If you want to work out whether you can dry laundry outside today, don’t just look at the sun in your weather app. Above all, check:
- the chance of rain in the coming hours
- the humidity
- the wind speed
- the temperature during the time the laundry is hanging outside
Can I dry my laundry outside today? Usually yes, if it stays dry, the humidity isn’t too high and you hang the laundry outside during the day. Whether you ask if the laundry will dry outside today or right now, it comes down to the same core question: can the outside air still draw enough moisture out of your laundry at this moment? If it’s muggy, foggy or rainy, the answer is often no, or only very slowly.
Drying laundry outside in winter
You can definitely dry laundry outside in winter. Many people think laundry only dries outside in warm weather, but that’s not true. Moisture also leaves textiles in cold air. When it freezes, the moisture first turns to ice and then gradually evaporates from the fabric. That’s why drying laundry outside in winter can work surprisingly well on dry days.
Drying outside is possible especially on clear winter days with low humidity and a little wind. Fog, sleet and persistent rain, on the other hand, are unfavourable. Drying laundry outside in winter does take more patience: thick fabrics need considerably longer than in spring or summer.
Does laundry always dry completely outside in winter? Not necessarily. Sometimes laundry feels stiff or cold at first while there’s still some moisture left in it. In that case, let it hang indoors for a while afterwards in a well-ventilated spot.
Drying laundry indoors or outdoors?
If you’re in two minds about drying laundry indoors or outdoors, outdoors is often the best choice when the weather allows. Drying outside saves energy, prevents extra moisture in the house and, for many people, gives the laundry a fresher smell. Drying indoors is more convenient when it rains or the outdoor humidity is high, but it raises the humidity in your home and calls for more ventilation. If you want to save even more, you’ll find extra tips on energy-efficient washing. Often dry indoors? Here’s how to prevent mold in the laundry room.
| Drying method | Advantage | Point of attention |
|---|---|---|
| Drying outside | Energy-efficient, fresh and often quick in good weather | Depends on weather and timing |
| Drying indoors | Always possible | More moisture in the house, good ventilation needed |
| Tumble dryer | Fast and predictable | Higher energy use and more wear |
Practical tips to dry your laundry faster outside
- spin your laundry well before hanging it up
- hang garments up with space between them
- turn thick fabrics halfway through
- hang bed linen open so the wind can blow through it
- use hangers for blouses, dresses and shirts
- bring the laundry in before the evening
- preferably don’t hang dark and delicate clothing in bright afternoon sun for hours
Does your laundry go stiff when you dry it outside? That mainly happens with towels and cotton in a lot of sun or wind. You can limit it by not leaving the laundry out too long, giving it a good shake before hanging it up and shaking the textiles loose briefly after drying.
When is it better not to dry outside?
Why not dry laundry outside? There are a few clear situations in which it achieves little or is impractical:
- when rain or showers are expected soon
- in fog or very high humidity
- when it’s already late in the day and evening is approaching
- with heavy air pollution, smoke or pollen, if you’re sensitive to them
Drying laundry outside in the rain is usually not a good idea. Even with only a light drizzle, your laundry absorbs moisture again. And even without rain, humid air can bring the drying process almost to a standstill.
Drying outside by season
Spring
Spring is often ideal for drying laundry outside. The air is regularly drier than in summer and there’s often enough wind. Do watch out for sudden showers.
Summer
In summer, drying laundry outside is often fastest, especially on dry days. In tropical, muggy weather, drying time can still go up because of high humidity.
Autumn
Drying laundry outside in autumn still works fine on dry, windy days. Start early in the day and bring the laundry in on time, because the air becomes damp more quickly in the evening.
Winter
In winter, drying outside works mainly on cold, dry days. In fog, damp cold or prolonged rain or snow, you’d do better to dry indoors with good ventilation.
Frequently asked questions about drying laundry outside
Can I dry my laundry outside today?
Yes, if it stays dry for the next few hours, the humidity isn’t too high and there’s some air movement. So don’t just look at the sun, but above all at the chance of rain, the wind and the humidity.
How long does laundry need to dry outside?
Light laundry is often dry within 1 to 3 hours in good weather. Thicker fabrics such as towels, jeans and bed linen usually need 3 to 8 hours, depending on the weather and the spin speed.
Does laundry dry faster outside than inside?
Yes, usually it does, if the air outside is drier and there’s wind. Drying outside provides more air circulation, while drying indoors is often slower because of still, more humid air.
Can you dry laundry outside at 10°C?
Yes. Drying laundry outside at 10°C is perfectly possible if the air is dry and it isn’t raining. It takes longer than on warm days, but it still works well.
Is 15°C good weather for drying laundry outside?
Yes, drying laundry outside at 15°C is often actually very suitable. With a little wind and reasonable humidity, laundry then usually dries quickly.
Can laundry dry outside in winter?
Yes, drying laundry outside in winter is quite possible on dry, cold days. When it freezes, moisture can still leave the fibers, although the process takes longer than in warmer seasons.
Why does laundry dried outside sometimes feel stiff?
That’s often due to sun, wind and mineral residues in the water. Towels in particular can feel stiff as a result. Leaving them out for a shorter time and shaking them loose afterwards helps.
Is it wise to leave laundry outside to dry overnight?
Usually not. At night the humidity often rises and dew can settle on the textiles. As a result, the laundry dries less well or even gets damper again.
Handy if you still need to finish drying indoors
Sometimes drying outside is almost enough, but not quite. Then a smart laundry room is handy for letting your laundry finish drying indoors briefly without things getting messy. Wasdroom doesn’t focus on specific outdoor drying products, but does share advice on drying solutions and a practical layout for your laundry room — in short, organizing your laundry room. Think of a fixed spot for a drying rack, pull-out or fold-away solutions and enough space to hang clothes up.
That way you combine the best of both worlds: first dry as much laundry outside as possible and then, if needed, let it finish hanging neatly indoors. Do make sure your clothes start out clean by sorting your laundry well, and preferably tackle stubborn stains first (see removing stains from clothing) before the clothes continue drying outside or indoors.
