Bucharest in September: Weather, Events and What to Expect

September is a sweet spot in Bucharest, with temperatures from 14–26°C (57–79°F) and sunrise at 6:55 AM. Bucharest Days mid-month fill the city with concerts and open-air events, while European Heritage Days open normally closed historic buildings. Outdoor dining and markets remain lively, and the cultural calendar is full. The tradeoff: some events draw crowds, but overall, September offers warm weather, manageable queues, and the city at its most welcoming. It’s one of the best months for both culture and comfort.

• Go early to Bucharest Days events for the best spots at concerts and open-air performances.
• Reserve tables at rooftop bars and outdoor terraces for sunset dining—these are in high demand in September.
• Head to European Heritage Days for free access to historic buildings not usually open to the public.
• Book accommodation at least 2 weeks ahead, as September is a popular month for city breaks and festivals.
• Avoid expecting summer heat—pack layers for cooler evenings and possible rain.
• Choose DIPLOMA Festival events for a look at emerging architecture and design talent.
• Skip indoor attractions during sunny afternoons—parks and outdoor events are at their best.
• Take advantage of wine harvest season for tastings at local bars and markets.
