Weather for a long bike ride — what to check before you go
A long bike ride asks a lot of you — and of the weather. What starts as a pleasant morning can turn into hours of rain, cold descents and draining headwind if you haven't planned properly. Knowing what to check — and where to check it — makes the difference between a great day and a difficult one.
See wind, rain and temperature along every kilometre of your route — not just at the start.
Why a city forecast isn't enough
For rides over 80 km, a simple morning weather app check isn't enough. Wind can shift direction mid-ride; rain arrives at the pass long before the valley; temperature at the summit can be 15 °C colder than at the start. RouteWeather shows you all of this mapped to your GPS route, hour by hour.
What changes along a long route
- Wind speed and direction change across passes and valleys
- Temperature drops ~6–7 °C per 1000 m of elevation gain
- Rain and storm timing differs from city to mountain
- Your start time determines whether you ride into headwind or tailwind
- Weather windows shift depending on how long your ride takes

Check weather for your long rideFrequently asked questions
What weather should I check before a long bike ride?
Check wind direction and speed along the full route — it determines effort and speed. Check rain timing by segment — especially at exposed sections and climbs. Check temperature at your highest elevation point — factor in wind-chill on descents. RouteWeather shows all three along your GPS line.
How does weather at higher elevations differ from the start?
Temperature drops 6–7 °C per 1000 m of elevation gained. Wind speed typically increases above tree line. Rain can fall at a pass while the valley below is dry. For any route gaining more than 500 m, checking conditions at the high point is as important as checking at the start.
Does weather change along a long route?
Always. That's the core reason route-based weather exists. Rather than checking one point, RouteWeather overlays conditions along your entire GPS line — so the weather for a long bike ride is never a surprise.
