May weather forecast
Greece

May is the doorway to summer in Greece, characterized by a significant upturn in warmth and sunshine. The southern islands and coastal stretches revel in splendidly sunny days, with blue skies dominating the horizon. This period witnesses a marked reduction in rainfall, and any occasional showers that do occur tend to be brief, leaving behind clear, refreshing atmospheres.

In the northern parts of Greece, May's influence is pronounced. The regions, once vulnerable to winter’s grip, now showcase clear skies and mild to warm temperatures. Even traditionally cooler locales like Florina embrace the summery trend, with day temperatures becoming increasingly comfortable. It's during this month that beach enthusiasts begin to eye the coastal regions, though the sea temperatures might still be on the cooler side for some.

Central Greece, under the brilliance of May, offers consistently warm days. The benevolence of the spring breezes gradually gives way to the more robust warmth of approaching summer, though it remains pleasant and not overpoweringly hot.

The average temperatures in the extreme north are in the warm 10°C (50°F) to 22.2°C (72°F) range, and the lack of rainfall is an open offer for tourists to visit the historic city of Thessaloniki.

With each day in May, daylight stretches even longer, casting a radiant glow over Greece's ancient ruins, picturesque landscapes, and vibrant cities. The foliage reaches its full splendor, with a riot of colors painting the countryside. As May edges towards its conclusion and June peeks around the corner, Greece prepares for the peak summer season, with even warmer days, balmy nights, and the beckoning call of the Mediterranean and Aegean Seas.
