What to pack, what to skip
- Lightweight, light-coloured clothing and a refillable water bottle
- Sunglasses, a brimmed hat and SPF 30+

- Avoid exposed ridgelines, small boats and rooftop viewpoints while gusts stay above 32 mph.
- If your dates are flexible, avoid June, July and September - historically the least comfortable months here.
