Intro

What’s the weather like in Bulgaria in September?

Located in southeast Europe, Bulgaria has a dynamic climate that’s different around the country. If you’re heading to the popular Black Sea coast in September then you’ll get high temperatures and lots of sun, as the long, hot summer continues into the month.

Balkan Mountains

The Balkan Mountains run through the middle of the country from east to west, and have a big impact on the weather in Bulgaria, which is the meeting point of Mediterranean and continental air masses. You’ll get cooler temperatures and more rain in the north than the south because of the mountains. Things are quite pleasant on the coast due to the Black Sea waters, where you’ll be kept cool by breezes.

Averages

Burgas on the Black Sea coast gives a good idea of what the weather will be like in this part of Bulgaria, and has an average high of 25ºC in September. Things can get a bit cool at night so bring some warmer clothes for the evenings, which dip to 14ºC. The sea temperature’s 22ºC, while humidity’s low. Average rainfall’s 34mm over four rainy days and you can expect 12 hours of daylight with eight hours of sunshine at a moderate UV level each day. The sun goes down at 7.45pm at the start of September.

Things to Do

Sunny Beach is one of Bulgaria’s most famous resorts, and sweeping sands that are great for you to lounge around on under a parasol. Obzor and Nessebar, nicknamed the ‘Pearl of the Black Sea’, are more peaceful spots to head to. Take to the seas and go on a sailboat tour, splash around at the biggest waterpark in Bulgaria, Ravda’s Aqua Paradise, or head out to the beautiful Strandzha Mountains which are just an hour from Sunny Beach.
