Romania Bucharest Weather in August — Climate Guide
August in Bucharest is high
August is high for Bucharest.
August matches July's pattern — Bucharest's hottest month tied with July (29°C peak), driest summer month (50mm + 8 wet days), and Carpathian Mountain hiking + Black Sea coast at peak. The summer-peak pricing + crowds + family travel volume make August the most challenging Bucharest month for first-time visitors — but the weather predictability + outdoor culture + Black Sea coast extension make it the canonical Romanian summer experience. Black Sea coast extension (Constanța + Mamaia 2.5h east) is the canonical August Romanian beach add-on.
