Average daily temperatures in September

September in Romania brings pleasant daytime temperatures averaging 75°F (24°C), with occasional warmer days reaching up to 82°F (28°C) early in the month. It's a welcome change from the heat of July and August, making it a great time for outdoor activities like hiking in the Transylvanian Alps or exploring on foot. You can expect sunny skies and moderate humidity.

Evenings are cooler, dipping to around 54°F (12°C), so it's a good idea to bring layers. If you’re heading to the Black Sea, the water remains swim-worthy at about 73°F (23°C), but it’s one of your last chances to enjoy beach weather before fall settles in. 

As for daylight, you'll still get plenty of time to explore, with around 12-13 hours of daylight, though the days are noticeably shorter than summer months.

What about the crowd and cost?

In terms of crowds and costs, September is a pretty good time to see Romania. 

There are far fewer tourists than in the busy summer months (July-August), but prices haven’t dipped to their winter lows yet. Hotels and attractions are fully operational, and you won’t need to plan months ahead like you would for a summer trip.

If you’re after better deals, October or May can be excellent choices, with similar mild weather with lower accommodation costs. That said, if you’re aiming to mix cultural experiences with a bit of beach time, September is hard to beat. See our full guide to when to go to Romania.

Mountain bike the trails around Poiana Brașov

You'll find perfect riding conditions around Poiana Brașov in September, with trails ranging from gentle forest paths to technical single tracks. The resort's ski slopes transform into flowing downhill routes, and the surrounding forests offer well-marked cross-country trails.
