Daily Temperature Variations
Mykonos experiences notable daily temperature swings, especially outside of summer. For example, in April, daytime highs may reach 22°C (72°F), but nights can cool to around 12°C (54°F).

The dry summer months ensure beach days are rarely interrupted by rain, but travelers in winter should be prepared for occasional wet weather.
Meltemi Winds: What They Are and When to Expect Them
The Meltemi is a strong, dry north wind that blows across the Aegean Sea, including Mykonos, mainly from June through September. It can reach speeds of 30 to 40 km/h (18 to 25 mph) or higher, cooling down the hot summer air but also making the sea rough. While the Meltemi is favorable for windsurfing and sailing, it can disrupt ferry schedules and beach relaxation on windy days.
Sea Temperature in Mykonos Throughout the Year
The Aegean Sea around Mykonos warms significantly in summer, with average sea temperatures around 24°C to 26°C (75°F to 79°F) in July and August. In spring and autumn, the water is cooler, ranging from 17°C to 22°C (63°F to 72°F), which may be refreshing for swimmers used to warmer seas. Winter sea temperatures drop to about 16°C (61°F), generally considered too cool for most swimmers.
Sunshine Hours and Daylight Variations
Mykonos enjoys abundant sunshine, especially in summer, with up to 12 hours of daylight per day in June and July. Winter months see shorter days, with around 9 to 10 hours of daylight in December. This variation affects sightseeing plans, as longer days provide more time for outdoor activities and beach visits during the summer season.
