In July a load hung out at six in the evening is dry before dark. By late October there is no evening left to hang it in, and the same load sits on a rack indoors for two days. Most of what changes about laundry when the days get shorter follows from that one fact.
The outdoor window closes before you get home
Line drying needs three things at once. Daylight, air movement, and air that is not already full of water.
Through summer all three are available for ten or twelve hours a day, so the window is wide enough that nobody has to plan around it.
As the days get shorter the usable part of the day narrows to a few hours in the middle, and those are the hours most people are not at home.
Washing hung out at five in the afternoon in November goes out into falling temperature and rising damp, so it takes water on rather than giving it up.
Leaving it out overnight is worse than useless once the air turns cold, because anything still on the line at dawn is wetter than it was at dusk.
No technique fixes this. The window has gone, and the choice narrows to indoors or a machine.
What indoor drying does to the rest of the house
A single washed load holds a considerable amount of water, and drying it indoors puts every bit of that into the air of the room.
The water does not disappear. It moves to the coldest surface it can reach, which is usually a window, an outside wall, or the corner behind a piece of furniture.
Windows running wet in the morning are the visible version. The version you do not see is damp settling into a wall, and that is where dark mildew marks start.
It also makes the house feel colder at the same thermostat setting, because damp air pulls heat away from skin faster than dry air does.
A rack in a closed bedroom is the worst arrangement of all, since the room is cool and the shut door keeps the moisture in it.
If a rack is the plan, put it in the warmest room available, leave the door open, and run an extractor fan or open a window elsewhere so the moisture has somewhere to go.
The clothes themselves get heavier
As the days get shorter the contents of the basket change as much as the drying does.
Jumpers, fleeces, thicker trousers, jackets and heavy socks all arrive at once, and each holds several times the water of the summer version of itself.
The same number of garments therefore fills a drum sooner and comes out of the washer much heavier, which slows every stage after it.
Bedding changes too. A thicker duvet and heavier blankets go on the beds, and anything that has been in storage since spring wants washing before use.
Coats turn up in the wash for the first time in months, and a coat is a full load on its own.
So the volume climbs at exactly the point the drying capacity falls, which is why autumn is the season people notice a routine failing.
Why damp things take so much longer now
Evaporation depends on how much water the surrounding air can still absorb and on how quickly that air gets replaced.
Cold air holds far less water than warm air, so outdoor air in November has little capacity left even on a day that feels dry.
Indoors, heated air has capacity, but a still room exhausts the air immediately next to the fabric within minutes and after that nothing moves.
That is why a fan aimed at a rack does more than turning the heating up. Air movement is the factor most people leave out of the calculation.
Thick items are worse than thin ones by a wide margin, because the water sits in the middle where no air reaches.
A towel that took four hours in July takes a day and a half on an indoor rack in November, and a jumper laid flat can take longer than that.
When the days get shorter a dryer stops being optional
Through summer a dryer is a convenience. Once the outdoor window closes it becomes the only reliable way to finish a load.
The alternative is not simply slower, it is a different result. Fabric that stays damp for a day and a half picks up a smell, and that smell is in the fibre rather than on it.
That is what people mean when they say indoor dried washing smells of the room. It was wet long enough for mildew to start, and running it again is the only cure.
A machine dryer also finishes thick items properly, which matters because a jumper that feels dry across the back is often still holding water in the cuffs and the seams.
And it takes the water out of the house instead of putting it into the air, provided the machine is venting or condensing properly.
The practical position once the days get shorter is that heavy items and anything with a deadline go in a dryer, while light items can still finish on a rack.
Getting more out of the dryer once you depend on it
The biggest single lever is the spin at the washer. A higher final spin takes water out mechanically, which is far quicker and far cheaper than taking it out with heat.
Do not fill the drum. Clothes dry by tumbling through moving hot air, and a packed drum has neither tumbling nor airflow through the middle of it.
Clean the lint screen every load. A screen that looks clear can be blinded by a film of softener residue, and the cycle stretches to compensate.
Sort by weight for drying even if you did not sort that way for washing. A load of towels finishes together. Towels mixed with shirts means the shirts cook while the towels catch up.
Take things out slightly damp and finish them on a hanger. The last stretch of drying costs the most heat and does the most damage to fabric for the least gain.
Wool, anything with elastic, and printed items belong on low or on air rather than on high.
What the routine looks like from October onward
The routine that worked in July has to change once the days get shorter, and the change is mostly about scheduling rather than about technique.
Wash earlier in the day where you can, so anything going on a rack has the warm part of the house ahead of it rather than behind it.
Stop holding damp items. Autumn is the season when a wet towel left in a bag turns into a second cycle, because nothing in the house is drying quickly any more.
Break bulky things out of the ordinary load. A duvet, a coat or a set of blankets is a job in its own right and it will not finish alongside shirts.
Take a smaller wash more often rather than one big one at the weekend, because drying is now the bottleneck rather than washing.
And do the seasonal changeover in one go rather than in pieces, since blankets and coats coming out of storage all want a wash before anyone uses them.
The Indianapolis part
The seasonal swing here is wide, and it is the shoulder weeks rather than deep winter that catch people out.
Summers are humid, so line drying is already slower than the temperature suggests. A hot still afternoon with heavy air dries washing less well than a cool breezy one, and households used to that lose the outdoor option gradually rather than all at once.
The real change arrives in October. As the days get shorter the evenings cool off quickly, and the outdoor drying window closes inside a few weeks, usually before anyone has thought to adjust.
Cold winters turn indoor drying into a heating question. Air inside a heated house in January is dry and will absorb water readily, so a rack does work, but everything it absorbs is water you then have to get back out of the house. Condensation on the inside of a window is the signal to open something.
The winter basket is heavier as well. Layering starts early here and the wash fills with fleece, thick socks and heavy trousers, which are the items least suited to a rack and most in need of a machine.
Where a heavy load actually dries
Once a rack stops keeping up, the question becomes how much air a machine can move through a load.
The machines at our self-service laundry on West 71st Street spin at a speed that takes far more water out before drying even starts, and the drums have the volume for a coat or a duvet to tumble properly instead of rolling round in a wet lump.
Our machines and the store are cleaned daily.
Our wash-dry-fold service covers the everyday laundry.
For general guidance, The American Cleaning Institute publishes a laundry basics guide that is a useful cross-check.
The short version
Once the days get shorter the outdoor drying window closes, usually before anyone changes their routine. Drying indoors puts every drop from the load into the air of the house, which turns up as condensation on windows and damp in cold corners, so a rack needs a warm room, an open door and moving air. The wash gets heavier at the same time, since fleece, thick socks, coats and blankets all arrive together. Damp things take a day or more indoors, and fabric left wet that long picks up a smell that only another cycle removes. Spin hard, dry the heavy items by machine, and keep loads small enough to tumble.
