Weather in Bulgaria and best time to go

Bulgaria

Bulgaria is located in the east of Europe and is thus free from the influence of the warm Atlantic Ocean. Although its shores are bathed by the Black Sea, it has a continental climate - warm summers and cold winters.

However, Bulgaria's more southerly location means that winters are milder and summers warmer than in continental climate areas further north (central Europe, southern Canada, etc.).

The climate is also influenced by the high mountains that fill much of Bulgaria. In the valleys and at higher altitudes it can be up to 15 degrees cooler than in the lowlands and on the coast.

When to go to Bulgaria

Of course, it depends on what you expect from your visit, whether you prefer sun, mountains or skiing.

Holidays by the sea

The main season for seaside holidays is June to September.

This is the period when most people visit Bulgaria. Holidays, the second half of June and the first half of September are the ideal months for swimming in the sea, but also walking in the mountains. The weather is stable and warm. Logically, you have to take into account the highest prices for accommodation and services.

The sea is warmest in July, August and early September, when the water temperature is between 23 °C and 26 °C.

Hiking in the mountains

The summer months are also the best for hiking in the mountains. However, the season starts earlier than at the seaside and runs from May to the end of September.

There is no snow in the mountains during this period and snow only covers small areas in the highest parts of the mountains.

April is also good for hiking, but only at lower altitudes, as there is often still plenty of snow above 1,500 metres.

Book your hotel in advance

Skiing

Snow is most certain on the slopes in January and February. The highest resorts with around 2,000 metres open in the second half of December and close around mid-March.

Towns and sights

You can visit towns and sights all year round. You can always take shelter from the weather in restaurants, cafés or museums.

July and August are the least convenient times, when the cities are sweltering hot.

If you're not too keen on the cold, avoid December to February.
