During the colder season, from late autumn to early spring (roughly November to March), when average temperatures range from 3°C to 7°C and nighttime lows can drop to freezing or below, you will need warm clothing.

Sunscreen and sunglasses will be useful on clear summer days. In September and October, the weather gradually cools down and rainfall may increase, so warmer layers and rain protection become necessary again.
