August is high for Sofia.
August matches July's pattern — Sofia's hottest month tied with July (28°C peak), driest summer month (55mm + 8 wet days), and Mt. Vitosha alpine hiking + Plovdiv Verdi Festival continues. The summer-peak pricing + crowds + family travel volume make August the most challenging Sofia month for first-time visitors — but the weather predictability + outdoor culture + Mt. Vitosha mountain access make it the canonical Bulgarian summer experience. Black Sea coast extension (Varna or Burgas 6-7h east) is the canonical August Bulgarian beach add-on.
