The average winter temperatures vary between -2° and 5°С.
Spring comes late, since the sea water warms up slowly, and generally the climate changes to warm only in May, when the temperatures reach 20°С.
Summer is dry and gently warm. It is characterized by breezes, arising as a result of the openness to sea.
The influence of the sea is felt in the autumn as well. It comes later but it is warmer because the sea water takes longer to cool.
