- sønglasses, a brimmed hat and SPF 30+
- Layers - the daily swing is 28°C, so mornings feel nothing like afternoons
- A warm mid-layer and gloves for early mornings and evenings
- A packable rain shell - 2 of the next 7 days carry a real chance of rain
- If your dates are flexible, avoid januar, februar and december - historically the least comfortable months here.
