What to pack, what to skip
- Layers - the daily swing is 64°F, so mornings feel nothing like afternoons
- A warm mid-layer and gloves for early mornings and evenings
- A packable rain shell - 3 of the next 7 days carry a real chance of rain
- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 40 mph.
- If your dates are flexible, avoid January, February and December - historically the least comfortable months here.
