Today’s Conditions at a Glance
Seasonal Guide
- Spring: Spring (Washington): Snow may linger above 6,000 ft through May. Muddy lower sections are common. Layers essential — mornings can be near freezing.
- Summer: Summer: Start before 8 AM to beat heat and afternoon thunderstorms. Afternoon temps at 5,400 ft can still be comfortable, but exposed sections get hot quickly. Lightning risk peaks on exposed ridges after noon.
- Fall: Fall: Often the best hiking season — stable weather, fewer crowds. Shorter days mean plan turnaround times carefully after September.
- Winter: Winter: Limited daylight and potential snow/ice above 5,000 ft. Check our daily score; many trails remain accessible with traction devices.
