Let your favorite weather app choose your route.
In lots of places (especially flat places), wind direction should be the number one factor in deciding which roads to ride. I was reminded of this during a recent week with lots of wind.
The idea is to ride a route that takes you into the wind on the way out. You’re feeling fresh and strong starting rides, so pushing into the invisible wall isn’t a big physical or mental strain.
It gets a lot tougher, though, if you sail through the first half of a ride with it at your back, then have to battle a headwind with waning energy.
Wind direction is especially important as cold weather sets in — often accompanied by brisk breezes.
Starting into the wind, you’re dry and comfortable. The airflow keeps you from overheating even though you’re putting out effort. When you turn back, you have a helping hand pushing to push you home.
Starting with the wind, you’ll overheat as you pedal in what’s effectively still air. You’ll sweat and get damp. Then when you reverse course, the cold headwind will penetrate and freeze you.
TIP: If you’ve already started your ride and you don’t want to stop and look at your phone, check flags to get a good read on wind direction.
The US National Weather Service website offers a nice “Hourly Graphical Forecast”. It shows forecast temperature, wind speed, gusts, and direction hour by hour. And a mess of other weather data.
Here’s the one for Boulder CO.

You may want to consider an evaporative scarf, cheap at A or WM. You can load it with water and put it in a zip lock bag, removing it and draping over your neck and down your chest when it gets hot. You’d be surprised how effective they are. Longer ride, carry two or recharge anywhere you can get water.
Been doing this for years, especially in cooler months here outside Boston. You just have to be careful of Murphy’s 2nd law of cycling: “When you start out with a head wind and reach your turnaround point, the wind changes direction.” I recently had the opposite happen. We started with a tailwind and at our turnaround point, we noticed a headwind on the return. How cool is that!
The Windy app is excellent. The free version gives you hourly wind direction forecast maps using five different models. I like the HRRR and NAM models best.
The Epic Ride Weather app includes a very useful wind map for a route during the time you’ll be riding it. It integrates with RideWithGPS and other route sources. It’s not free, but I’ve found it to be very worthwhile.
