- Meltwater on road, gravel patches, occasional snow walls
- Cold summit temps even on sunny days
➡️ Most unpredictable season
☀️ Summer (late June–Aug)

➡️ Peak cycling season
🍂 Autumn (Sep–Oct)
- Crisp air, clear views, low traffic
- Early snow possible late October
- Temperatures drop quickly after sunset
➡️ Often best balance of weather + quiet roads
🌬️ Key conditions cyclists should expect year-round

- Strong wind exposure near summit ridges
- Sudden storms even when forecast looks good
- Long climb duration → changing conditions during ascent
