Lisbon is the standout destination this week, with an average high of 27.1°C and 6 fine days out of 7, according to Open-Meteo. The city’s dry conditions and partly cloudy skies make it ideal for exploring historic neighborhoods or enjoying the coast.
Close behind is Barcelona, where temperatures reach 30.3°C and all 7 days are forecast to be fine. The minimal rainfall of just 1 mm ensures perfect conditions for beach days or strolling along La Rambla. Istanbul also offers 6 fine days, though with slightly cooler highs of 26°C and more cloud cover, making it a solid choice for city sightseeing despite 17.2 mm of rain.
For those seeking coastal beauty, Dubrovnik delivers 28.1°C highs but only 5 fine days, with 32.8 mm of rainfall likely. The mix of sun and showers could work for flexible travelers, though beach plans may need adjusting. Meanwhile, Maui is best avoided this week, with only 2 fine days and persistent drizzle.
