What to pack, what to skip
- A warm mid-layer and gloves for early mornings and evenings

- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 55 mph.
- If your dates are flexible, avoid January, February and December - historically the least comfortable months here.
