Winter Biking Tips for San Mateo County Commuters

Winter doesn’t have to mean putting your bike away. With shorter daylight hours and wet weather, conditions can feel more challenging—but with the right preparation, riding through winter can be one of the most rewarding ways to commute. You’ll avoid traffic, stay active, and often arrive feeling more energized than if you had driven.
Below are five key strategies to help you ride comfortably and confidently through the season.
1. Ease Into Winter Riding
Winter riding is not all-or-nothing. Start gradually and get used to darker evenings and occasional rain.
Begin with shorter rides to dial in your gear.
Alternate biking days with public transit or drive part-way and bike the rest.
Consider combining your ride with Caltrain or SamTrans to shorten your commute.
Building winter riding habits slowly helps keep it enjoyable rather than overwhelming.
2. See and Be Seen: Riding in the Dark
After daylight savings, many commutes take place after sunset. Visibility becomes essential.
Lights:
Use a bright white headlight (300 lumens minimum; brighter is better).
Use a solid or flashing red rear light.
Add a second light on your helmet or bag for extra visibility.
Reflectivity:
Add reflective tape to your bike or bags.
Wear reflective ankle straps or outer layers.
Choose lighter colored or high-visibility clothing.
Cold weather drains batteries quickly, so charge lights regularly and carry a backup.
3. Staying Comfortable in Rain and Wet Conditions
Gear to Stay Dry & Warm:
Wear a waterproof or water-resistant jacket or poncho.
Use waterproof shoes or carry extra socks.
Choose gloves with good grip for wet handlebars.
Use balaclavas or beanies to protect yourself against the cold.
Bike Setup:
Install full fenders to reduce road spray.
Use waterproof panniers or a backpack rain cover.
Riding Technique:
Slow down and brake earlier.
Avoid sharp turns on wet pavement.
Stay relaxed and absorb bumps with your knees and arms.
Watch for puddles that may hide potholes.
4. Improve Traction and Keep Tires Ready
Cold temperatures lower tire pressure, so check it frequently.
Inflate tires to the low end of their recommended range for better grip.
Check pressure before each ride—air loss is faster in winter.
Consider slightly wider or lightly treaded tires.
Puncture-resistant tires or liners can help prevent flats in wet weather.
5. Choose Safer Winter Routes and Learn More
Route Tips:
Favor protected bike lanes and well-lit streets when possible.
Avoid low-lying streets with poor drainage.
Use Google Maps to check the safest route.
If a bike lane is full of water or debris, take the regular traffic lane.
