I'm going to let you in on a little secret of mine. I've been heavily relying on technology for line drying my clothes outside. And, it's not some super duper fancy rack that hangs the clothes by itself. No, it's something on the intarwebs.
If you are planning on letting the sun and the wind help dry your clothes, you're going to need some help in predicting the weather for the day and week in order to plan your laundry accordingly. Since it's nearly impossible to know what the weather is going to do from hour to hour, using some modern technology can help you know when to bring that laundry back inside. That's how I've been planning my laundry for the last few weeks.
What is it already? It's the weather.com hour-by-hour weather report. I've found it to be relatively accurate and it's super helpful to know whether or not it will get sunny and when or whether I should wait to put out my clothes. Since it also tells you what the percent chance of rain it will be, I can hedge my bets that way as well.
For example, the current hourly weather report for my area is rain, followed by sun in the late afternoon, so I know I will be keeping it inside most of the day. But, when there's a break in the weather, I'll know about that too so I can huck it out there for a few hours.
Go check it out. You can thank me later.
If you still haven't signed up for October's Hang 'Em Dry Challenge, where you pledge to air/line dry all your laundry, git on over there and do it!
