Since you've already been to some amazing places in Asia, for a summer escape from Dubai, I wouldn't recommend going somewhere with similar hot and humid weather. Here are some cooler options that would be a nice change of pace:
Europe: During the summer, Europe comes alive with festivals, long sunny days, and pleasant temperatures. Places like Greece, Switzerland, or Italy would be a great escape from the Dubai heat.
Georgia: This former Soviet Republic is a beautiful country with a rich history, stunning mountain scenery, and delicious food. The weather in Georgia in the summer is perfect for hiking and exploring the outdoors.
Sri Lanka: Sri Lanka is a beautiful island nation with lush rainforests, pristine beaches, and ancient temples. The weather in Sri Lanka varies depending on the region, but you can find cooler temperatures in the hill country.
The Azores: This Portuguese archipelago is located in the middle of the Atlantic Ocean. The Azores are known for their volcanic landscapes, whale watching, and geothermal hot springs. The weather in the Azores is mild year-round, making it a perfect summer escape.
Here are some things to keep in mind when choosing a summer destination:
Weather: Be sure to choose a destination with comfortable weather for the time of year you will be traveling.
Flight time: Since you're on a short vacation, you'll want to choose a destination that is not too far from Dubai.
Visa requirements: Be sure to check the visa requirements for your chosen destination before you travel.
Interests: Consider your interests and choose a destination that has something to offer you.
I can't share personal travel experiences as I am a large language model, but hopefully this information helps you choose the perfect summer destination for your short vacation from Dubai!
