Bulgaria in February

May through September gives you the full Bulgaria experience, though each month serves different purposes. May brings wildflowers to mountain meadows and comfortable temperatures for hiking—perfect for Rila and Pirin national parks. June heats up but stays pleasant, ideal for mixing cities with outdoor activities. July and August turn the coast into party central while mountains offer cool relief, though expect crowds at popular spots like the Seven Rila Lakes. September might be the sweet spot—warm days, cool nights, harvest season, and summer crowds heading home. Ski season runs December through March in Bansko and Borovets, with January-February offering the most reliable snow. Winter transforms Sofia into a cozy base for exploring, though mountain weather gets serious. Avoid November and early April—muddy hiking conditions and unpredictable weather make outdoor activities frustrating.
