The weather in Bulgaria: an all-year guide

For travelers and tourists who intend to visit the country, the weather in Bulgaria is perhaps one of the most important factors. How could you plan when to go and what part of the country to visit without having the slightest idea of Bulgarian weather?

To locals like me, weather may be mostly a matter of small talk (and regular complaints because believe it or not, we like to complain about the weather too), but I’ve noticed that during my travels, weather information is one of the first things I check before I depart or even plan a journey. To help fellow visitors, kashkaval tourist prepared this all-year guide to the weather in Bulgaria.

In a nutshell: the key Bulgarian weather facts

In general, you can expect a lot of sunshine and dry conditions throughout the year in Bulgaria

In general, you can expect a lot of sunshine and dry conditions throughout the year in Bulgaria

Bulgaria is not a huge country even by European standards, so weather variations between the different regions are usually no more than 6-7 °C. That is if you exclude the high reaches of the mountains, where the altitude makes it dramatically colder.

Bulgaria’s climate is a combination of continental and Mediterranean influences, which means the country has four quite well-defined seasons (spring, summer, autumn and winter) and temperatures vary dramatically in different times of the year. In general, you can expect summers to be quite hot and dry and winters to be snowy and freezing, with spring and autumn providing a transition between the two.

The warmest parts of Bulgaria are in the southwest, where the Mediterranean climate effects in the valleys are particularly strong. The seaside has a mild subtropical climate heavily influenced by the Black Sea’s presence. The plains and lowlands in the north and south experience continental weather (with the south usually a bit warmer) and the mountains are known for their Alpine climate conditions.

To give you an idea: the highest temperature ever recorded in Bulgaria is 45.2 °C, while the lowest record stands at −38.3 °C. That’s a staggering difference of 83.5 degrees!

Bulgarian spring: greenery and tree blossoms

After the harshness of winter, the blossom of trees signals the beginning of spring at some point in March. As the temperatures gradually increase and the remaining snow melts, the fields and meadows are at their greenest and the landscapes can be incredibly scenic.

In spring, you can expect temperatures of 15-25 °C in Bulgaria, steadily increasing from March to June. There’s less sunshine than in the summer, but normally it doesn’t rain a lot either. The weather can be quite foggy and turbulent in general, especially in March, which has a reputation for being unpredictable.

Mountains above 2000 metres remain snowy until June-July, so hiking is a bit challenging in spring, and the waters of the Black Sea are too cold for comfortable bathing until mid-June or so.

Bulgarian summer: sunbathing and hiking delight

Bulgarian summer rolls around with the beginning of June, when temperatures reach above 30 °C. July and August are the hottest months and the sun can be quite strong at midday indeed. Temperatures above 35 °C are not uncommon and it can sometimes be nearing 40 °C!

Summer days are usually clear and sunny, though when it rains, it pours in the form of brief but violent summer storms (and those can be hailstorms too, so better find some shelter!).

This may seem like a whole lot of heat, but thankfully, Bulgaria offers a lot of ways to escape. The gentle breeze of the seaside and the refreshing Black Sea (which in summer is in the 20s) make for a very pleasant summer holiday. And don’t forget, the mountains are at their most inviting with their cooler temperatures and chilly nights around the fire!

Bulgarian autumn: the smell of roasting peppers

September and October can still be quite warm and pleasant in Bulgaria

Summer tends to end by mid-September, when temperatures drop a bit and the days get shorter. September and October can still be quite warm and pleasant and in general autumns are not particularly rainy compared to the rest of Europe. Autumn is also the season when grapes are harvested to make wine and grannies prepare supplies for the coming winter – you cannot mistake the trademark smell of roasting peppers in September and October!

Bulgarian autumn boasts temperatures around 10-25°C, gradually decreasing as winter approaches by the end of November and early December. Early September may still be a good time to hit the seaside or ascend into the mountains, but by October it usually gets too cold for that.

Bulgarian winter: snow and ski paradise

Weather conditions are often perfect for winter sports in Bulgaria

Winters starts with December, when temperatures begin to drop below zero. The end of December usually brings the first snow of the year and until March it usually snows rather than rains. Though it can stay below zero for weeks in a row (temperatures around -5 to -15°C are common), the days can still be regularly clear and sunny. In fact, for many places in Bulgaria, winter is one of the driest seasons.

Clear and sunny with below zero temperatures keeping snow on the ground for a long time – sounds like perfect skiing and snowboarding conditions, doesn’t it!? And indeed, late December to March (whenever there’s snow) is Bulgaria’s winter season, when resorts like Bansko, Borovets and Pamporovo attract local and international tourists to their ski trails.

  1. Hi,

    What would the temperature be like in the first week of December ? We are planning to visit with 2 young children, so what can we do in around 3-4 days, while staying at Sofia? Will it be too cold to do day trips to monasterties and churches?



    • Hi Anna! It shouldn’t be too cold if you guys are properly dressed. December in general is warmer than January or February, and early December should still be relatively mild. It’s likely that by then we won’t have had any snowfall in the cities at all, for example. Temperatures may fall slightly below freezing at night and rise up to 8-10°C during the day. You’d be able to get to places like the Boyana Church or the Rila Monastery no problem 🙂

  2. Hello

    we are intending to drive from Sofia to Vidin on the 21st January 2017. Assuming there are no issues with the flight would anyone care to hazard a guess about whether the roads will be passable or not? Vidin is where we will be staying but hoping to travel backwards and forwards to Mokresh near Lom over the week.Who thinks we should cancel and go to Butlins instead?

    Looking forward to hearing from you.

    • Hi Linda,

      Right now the weather is quite wintery and conditions on the roads aren’t really good. But as far as I know, Vidin has remained accessible via the Hemus motorway (through Botevgrad, Vratsa and Montana). The shortest route from Sofia, via the Petrohan Pass (what you’d get as a suggestion on Google Maps), is currently closed due to multiple avalanches. And I wouldn’t bet on this one in winter conditions.

      But the forecast is that the weather will get milder by 21 January, so I wouldn’t cancel. It’s more than likely that the roads will be passable. It’s currently a beautiful snowy winter in Bulgaria, even the Danube may be frozen which doesn’t happen often. I’d say go ahead with your plans and enjoy some real winter which you can’t see in the UK 🙂

    • Hi Irene! That’s a good question. Generally, the extreme southernmost places are the warmest, as long as they’re at a low elevation. That means basically the Struma Valley in the southwest (Sandanski and Petrich), some parts of the Eastern Rhodopes (around Ivaylovgrad) and the southern Black Sea coast (south of Burgas, particularly Tsarevo and the like). As far as I know, these places get little if any snow and they have a significant Mediterranean influence, so they can semi-reliably support palm trees and olives at sheltered locations. But even Plovdiv has a much milder winter than Sofia and North Bulgaria, with a lot less snow.

      • I only have a limited budget to buy a house, could you suggest any areas that would be safe aswell as the price, and really where its a bit warmer . Irene fawcett

        • Hello Irene,
          I too would like to buy a house in bulgaria and like you I have limited funds. I have exactly the same questions as you do.
          I am also wary of which agent to contact as I have heard there are some companies that are less than honest.
          Regards Morag McGeehan

  3. Hi thank you for all the information you have already provided. I’m trying to book a short weekend break away with some snow. Although I would love to ski its not on the agenda due to costs. Could you recommend an area that might be cheaper away from the slopes and would the 22nd December be to early for snow. Thanks in advance

    • Hi Parranavah! You’re welcome. 22 December may be early for skiing, but the high mountains will definitely have some snow already by then. Even staying in Sofia and going up to Cherni Vrah might do it. Otherwise for a significant snow cover, you should be up high in Rila or Pirin, above 2000m. Maybe stay in Borovets and take the cabin lift up to Yastrebets or the same with Bansko and Todorka. Or Dobrinishte and go up to Bezbog with the chairlift, this would be a good budget option.

      Bear in mind that this is the weekend just before Christmas Eve, so people will be on holiday and it may be busy. But at the same time, it’s not high season for skiing. Just book ahead 🙂

  4. Hello
    Brilliant report on the weather. I always love reading your information.
    I am intending to look for a property in Bulgaria to buy. My problem is where to begin my hunt. Can you give me any suggestions of the warmest villages / towns to begin my search. I’d hate to live in a very very cold temperatures.
    Thankyou Morag

    • Hi Morag! Glad that you find my blog useful. I answered this question above in more detail, but in short: consider the areas around Sandanski and Petrich (southwest), Ivaylovgrad (southeast) and the southern Black Sea coast, especially south of Burgas. These have strong Mediterranean and/or subtropical influences and have the mildest winters in Bulgaria on average.
