What to pack, what to skip
- A warm mid-layer and gloves for early mornings and evenings
- Insulated outer layer, hat and boots with grip for ice
- A packable rain shell - 2 of the next 7 days carry a real chance of rain
- Avoid high-elevation trails without traction devices - frozen surfaces persist in shade all day.
- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 45 mph.
- Avoid swimming outside patrolled areas - waves are running at 2.8 m.
- If your dates are flexible, avoid April, July and August - historically the least comfortable months here.
