May is one of the best months to visit Bulgaria, with daytime highs typically reaching 22–26°C along the Black Sea coast and 20–24°C inland. Check the live forecast above for your exact travel dates, as conditions can shift from warm sunshine to short afternoon showers.
What is the weather like in Bulgaria during May?
Bulgaria sees a transition from spring to early summer in May. Coastal resorts like Sunny Beach and Nessebar enjoy sea temperatures around 16–18°C, too cool for prolonged swimming but pleasant for beach walks. Inland cities such as Sofia and Plovdiv experience more rain, with May being one of the wettest months. The southern Riviera and Obzor tend to be slightly warmer than the northern coast.
Should I pack for rain or sun in Bulgaria in May?
Pack for both. Light layers, a waterproof jacket, and comfortable walking shoes are essential. The weather in Bulgaria at the end of May is usually warmer and drier than early May. Evenings can feel cool, especially in mountainous areas, so bring a jumper.
If you are considering a trip later in the season, check the 10-day UK forecast before flying, as UK weather can affect flight arrival times. For those weighing up options, our UK weather hub can help you compare conditions at home.
