Sud-Muntenia regional averages · Historical patterns, not a forecast. Gaps mean no data. Crowds compare months within this region.

Very-good-or-better weather scores: April to October. No month has a poor weather score.

There is no real busy season: the quietest month, March, still runs at 51% of the busiest.

The two busiest months account for 25% of annual overnight stays.

On the 2024 EU comparison, Romania's restaurants and hotels are well below EU average.

Before you go

Pack a little context.

Fewer crowds

Hotel stays are steady all year.

Hotel stays vary little: the busiest month has only 2.0× the nights of the quietest, so pick on weather.

Good weather

September has the highest weather score.

Very good or better April to October. September has the highest displayed weather score (9.6/10).

Lower prices

January to March.

These are three lower-price months on Romania's historical 2024–2025 national hotel index. It cannot identify this region's cheapest bookable rooms.

School holidays

School breaks meet steady visitor levels.

Hotel stays here vary little through the year, so US school breaks don't put you in a busier season.

Local school holiday dates are unavailable in our calendar; this does not mean schools are open.

About these answers

These seasonal facts stay the same when you change your priorities; your Overall recommendation updates above. Prices retain the scope stated beside them. Full methodology.

Crowds: Eurostat nights spent at tourist accommodation establishments by month and NUTS 2 region, per 1,000 inhabitants, divided by days in the month. "Season here" is the month's figure as a share of this region's busiest month. "Visitors" ranks overnight visitors per resident against all Europe's regions that month. Weather: Holiday Climate Index (Scott et al. 2016; Rutty et al. 2020) computed from ERA5 reanalysis with daily highs, night lows and rain days corrected from open national weather-service station records and population-weighted to the region.
