Varna Weather Overview:
As Bulgaria’s premier beach resort you’d expect good weather here and for most of the year you’ll get it. Summers are hot and humid although its position on the Black Sea tempers the heat with onshore breezes. Winters are mild in general although snow isn’t out of the question, especially overnight when temperatures can drop to freezing or below.
All Time Highs and Lows:
In July 2003 the temperature in Varna reached 41.4C whilst on February 10th 1929 -24.2 was recorded.

Weather Science:
Under the Koppen Climate Classification, Varna enjoys a humid sub-tropical climate but the proximity of the Black Sea and the Mediterranean has a big influence on the weather. Also exerting a strong influence is the hinterland of Eastern Europe and Western Russia giving continental aspects to Varna’s climate

The Seasons:

Spring: Once it starts, spring rushes on apace. March temperatures are already well up on February’s and from March to May, the daily average will increase from around 6C to 15C, meaning days where the temperature could reach the low sixties in March and the low seventies in May. Sunshine hours make a comeback from an average of four in March to seven in May whilst rainy days stay around nine each month.

Summer: Summers are almost perfect in Varna. Daily temperatures in July and August are in the nineties whilst sunshine hours average nine a day. You’ll still get days with rain but this is likely to be during the thunderstorms that punctuate the Varna night as humidity rises. Nights will be hot and sticky so air-conditioning is a must.

Autumn: The holiday brochures will tell you that summer lasts until mid-October and looking at the temperatures and sunshine levels you’d be inclined to agree. It’s not until November that the temperature drops away enough to mean that lying on the beach isn’t wise. Until then you’ll see temperatures still in the seventies and around five to six hours of sun each day.

Winter: December is the first real chilly month and is followed by temperatures not much more than freezing in January and February. The warm sea keeps the area close to the water free from snow and frost but further inland it gets very chilly. You’ll get the most days of precipitation in these months and they’ll be a little gloomy, averaging only three hours a day of sun.

Best Time to Visit:
The best times to visit and have a pleasant stay are in May and in the early autumn. At those times, the humidity isn’t there, making evenings pleasant whilst days are warm and sunny. If you’re a real sunshine lover July and August are perfect but you’ll have to put up with the holiday crowds.
