Sofia, May 2023

I love traveling to European cities. In May, the opportunity arose to visit the city of Porto. Of course, I didn’t even think about swimming in the sea, because the water temperature is not suitable for this. But for visiting sights and excursions, May is a suitable month. It's already quite warm. During the day the temperature remained around twenty degrees. But at the same time, it’s not hot, which can also be a plus for excursions. True, one day out of two weeks there was not much rain, which quickly ended and did not really interfere with the walk around the city.
