Istanbul’s Perfect Week: 7 Days of Sunshine and 30°C Heat

Istanbul leads the pack with 30.8°C and 7 fine days; see where else shines and where to avoid drizzle this week

Istanbul's Perfect Week: 7 Days of Sunshine and 30°C Heat

Istanbul is the standout destination this week, with a perfect forecast of 7 fine days and highs of 30.8°C, according to Open-Meteo. The city’s mix of history, culture, and coastal charm makes it ideal for long days of sightseeing and exploring.

Close behind, Barcelona and Dubrovnik also offer excellent weather, with 6 and 7 fine days respectively. Barcelona’s 31°C highs are perfect for beach days and strolling along La Rambla, while Dubrovnik’s 33.5°C heat is ideal for exploring its historic walls and swimming in the Adriatic.

Lisbon, with 5 fine days and highs of 27.8°C, is another solid choice, though a few showers are expected. The city’s hills and coastal paths are best explored in the cooler morning hours.

If you’re hoping to escape to the tropics, Maui might disappoint this week, with only 2 fine days and mostly drizzle in the forecast. Those seeking sunshine might want to look elsewhere in the Pacific or consider the Mediterranean alternatives above.
