What to pack, what to skip
- Lightweight, light-coloured clothing and a refillable water bottle
- Sunglasses, a brimmed hat and SPF 30+
- Layers - the daily swing is 73°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.
