Best time to go to St Vlas
The sun shines virtually all the time during the summer months in Bulgaria. In July and August, temperatures regularly climb above 30°C and swimmers can enjoy waters that nudge the mid-20s. Even in spring or autumn, you’ll still be able to enjoy beach weather, with just a few rain showers a month and the mercury hovering around the low to mid-20s. Temperatures can cool down in the evenings, though, so it might be a good idea to pack a light jacket or jumper.
