What should I wear running in cold weather?

What Should I Wear Outside analyzes the current temperature, wind, humidity, and your running pace to recommend the perfect clothing layers. Generally, you'll want to dress for 10-15 degrees warmer than the actual temperature since running generates heat. Our tool factors this in automatically and suggests appropriate tops, bottoms, outerwear, and accessories.

How does the weather clothing calculator work?

Our calculator uses real-time weather data including temperature, feels-like temperature, wind speed, humidity, and precipitation. It then adjusts based on your activity level (running warms you up more than walking) and your personal temperature preference. The result is a customized clothing recommendation with specific layers and accessories.

Is this clothing recommendation tool free?

Yes! What Should I Wear Outside is completely free with no login required. All your preferences are stored locally in your browser, and there are no subscriptions or hidden fees.

What activities does this support?

The tool provides weather-based clothing recommendations for running, walking, biking, and standing outside. Each activity generates different amounts of body heat, which is factored into the clothing suggestions.

What to wear cycling in different temperatures?

Cycling recommendations account for wind chill since you're moving at higher speeds. The tool suggests appropriate cycling clothing based on temperature, wind, and weather conditions, adjusting for the cooling effect of moving at bike speeds.

About What Should I Wear Outside

Hey! I'm Chase and I created this free weather-based clothing recommendation tool to solve a problem I faced every day: figuring out what should I wear when running outside. I always over or underdressed, so I built this simple calculator that tells you exactly what clothes to wear based on temperature, weather conditions, and your activity level.

Whether you're running, walking, biking, or just standing outside, this tool helps you dress appropriately for the weather. It considers wind, humidity, precipitation, and even adjusts for how much your activity will warm you up. Best of all, it's completely free and requires no login!
