Reading the weather + headwinds
Open-Meteo data per time station + signed wind component. Plan sleep around bad weather, not in spite of it.
Weather is fetched from Open-Meteo every 15 minutes for the rider position and the next six time stations. The app classifies wind into headwind / tailwind / crosswind based on the segment bearing — not the raw direction.
Wind component reading
| + value (green) | Tailwind. Push harder, take less food. |
|---|---|
| − value (red) | Headwind. Drop into aero, conserve effort. |
| near zero | Crosswind — Follow vehicle drives closer to block. |
Auto-action triggers
- Headwind > 15 km/h → WARN aero tuck + reduce 5%
- Temp > 35 °C → AMBER pre-cool + ice socks
- Temp < 7 °C → INFO stage warm layers in follow
- Precip > 2 mm → WARN rain shell + check tire grip
Tactical sleep
When a 4-hour bad-weather block is forecast, time a 60-minute sleep break inside it. You lose less by resting in the storm than by riding through it.
