Temperatures fluctuate between cool and warm throughout the year, so being able to add or remove layers will ensure your comfort. Regardless of the season, be sure to bring comfortable walking shoes, as you'll likely want to explore the scenic surroundings. Also, don't forget sunscreen and a hat, as the sun can be strong even on cooler days.

If your trip falls between November and February, be prepared for cooler weather, especially in the mornings and evenings when temperatures can drop to 10-11°C. During this time, you'll need warm clothes: sweaters, a fleece, a light but warm jacket (preferably windproof), long pants, and closed shoes. Although this is a drier season with less rainfall (2-3 mm per month), a light waterproof jacket or an umbrella might still come in handy for occasional showers.

In transition months such as March, April, and October, the weather can be mixed, so a combination of light and warmer items, along with being prepared for rain, is the best approach.
