Yes, the meltemi wind often picks up in July and August, especially in the afternoon. It can feel strong on exposed cliffs and boat trips, so pack a light jacket or scarf for evenings.
Can I visit Santorini in winter?
You can, but many hotels, restaurants and ferry connections operate on reduced schedules. The weather is mild but rainy, and some attractions close. It is quiet and cheaper, but less convenient for a full holiday.
Is the weather different between Fira and Oia?
Not significantly — both towns sit on the caldera rim and share the same climate. Oia can feel breezier due to its exposed position, but temperatures are nearly identical across the island.
