What to pack, what to skip
- Sunglasses, a brimmed hat and SPF 30+
- Layers - the daily swing is 64°F, so mornings feel nothing like afternoons
- A packable rain shell - 2 of the next 7 days carry a real chance of rain
- If your dates are flexible, avoid January, February and December - historically the least comfortable months here.
