Istanbul's Perfect Week: 7 Days of Sunshine and 28°C Highs

Istanbul is the standout destination this week, with a perfect forecast of 7 fine days and an average high of 28°C, according to Open-Meteo. The city’s dry, partly cloudy skies make it ideal for exploring historic sites like the Hagia Sophia and enjoying rooftop dining with views of the Bosphorus.

For those seeking similar warmth, Lisbon and Dubrovnik also promise 7 fine days this week, with highs of 30°C and 31.9°C respectively. Lisbon’s mostly cloudy skies won’t deter sightseers, while Dubrovnik’s sunny, dry weather is perfect for coastal walks and beach days. Barcelona, meanwhile, offers 6 fine days and a high of 29.9°C, though expect some rain.

If you prefer milder temperatures for hiking or city exploration, Cape Town delivers with 6 fine days and a high of 23.2°C. The minimal rainfall of 2.9 mm ensures comfortable outdoor activities. Avoid Barcelona if you’re hoping for a completely dry trip, as it sees 14.1 mm of rain this week.
