Bucharest in September offers a transition from summer’s heat to autumn’s gentle embrace. Typically, daytime temperatures average between 20-25C (68-77F), creating pleasant conditions for outdoor activities. Evenings become noticeably cooler, often dipping to 10-15C (50-59F). This period generally experiences less rainfall compared to the later autumn months, with sunshine still prevalent. Visitors can expect an average of six hours of sunlight per day.
This time of year presents an ideal opportunity to explore the Romanian capital. The agreeable climate allows for comfortable sightseeing, leisurely strolls through parks and gardens like Herstru Park or the Botanical Garden, and al fresco dining experiences. The transition period also signifies a less crowded city as the summer tourist season wanes, potentially offering lower prices for accommodation and travel. Historically, September marked the beginning of the harvest season in Romania, a time of celebration and abundance, a tradition that continues to influence cultural events and festivals throughout the country.
