Given that the number of rainy days can be significant in almost any season, especially from March to October when they vary from 12 to 24 per month, an umbrella or a quality raincoat should be an essential part of your luggage. Even in months with less precipitation, such as January, February, or December, an unexpected rain shower is not out of the question. Layering will allow you to easily adapt to temperature changes throughout the day, which is especially relevant for the transitional seasons of spring and autumn.
