Best time to visit
Spring (April to June) and autumn (September to October) are the most comfortable times. Days are warm, the sea is usable, and there are fewer crowds than in peak summer.
July and August are busy and hot, which suits high-season rentals. Winter is quiet and mild, and it appeals to long-stay visitors from colder countries. This mix supports rental demand across most of the year.
- Spring and autumn are the most comfortable
- July and August: hot and busy, strong rental season
- Winter: quiet, mild, good for long stays
- Year-round demand helps rental income
July and August can be very hot, and near the coast the air can feel humid. Midday heat can be tiring if a property has no air conditioning or shade. Autumn can also bring short, heavy rain storms that pass quickly but can be intense. These are normal for the region and easy to plan around.
