The best time to visit Romania is May to June and September to early October: in Transylvania, afternoons hover around 21 to 25 °C (70 to 77 °F), the mountains are accessible and the medieval towns can be visited without excessive heat. July and August suit the Black Sea and high mountain roads, but Bucharest then exceeds 30 °C (86 °F) in the afternoon. Bucharest, the Black Sea and the Carpathians can be seen at a glance on our map of Romania.
Romania has a continental climate: cold winters, hot and stormy summers, pleasant springs and autumns. The Carpathian arc separates regions with different profiles: Transylvania, on a plateau, is cooler; the southern plain around Bucharest is the hottest in summer; the Black Sea coast and the Danube Delta are the driest. Here is how to choose your month, based on official climate normals.

Romania’s seasons: pros and cons
Spring (April to June): greenery and birds
Spring is an excellent season for the cities and the Danube Delta. In Bucharest, average highs rise from 18.5 °C (65 °F) in April to 28 °C (82 °F) in June. The hills of Transylvania and Maramureș are very green. The delta then hosts many migratory birds, including pelicans. In the mountains, snow persists on the peaks and high-altitude roads normally stay closed until early summer.
- Pros: green landscapes, pleasant temperatures, moderate prices, the Danube Delta at its best for birds
- Cons: frequent storms in May–June, high mountain roads still closed, busy Orthodox Easter weekend
- Our tip: late May–June to combine Bucharest, Transylvania and the delta
Summer (July–August): mountains and the Black Sea
Summer is hot on the plains: about 30 °C (86 °F) in the afternoon in Bucharest in July–August according to the normals, more during heat waves. It is the season of the Carpathians (hiking, scenic roads such as the Transfăgărășan) and of the Black Sea, around Constanța and Mamaia. Transylvania stays cooler: about 27 °C (81 °F) in the afternoon in Sibiu and Cluj-Napoca. Our guide to visiting Cluj introduces the city.
- Pros: accessible mountains, swimming in the Black Sea, festivals, long evenings
- Cons: heat in Bucharest, crowds and higher prices on the coast, thunderstorms in the mountains
- Who is it for? Hikers, families and road-trippers
Autumn (September–October): light and colorful forests
September stays mild (25 °C (77 °F) in the afternoon in Bucharest, 22 °C (72 °F) in Sibiu) and October is pleasant. The Carpathian forests take on autumn colors and the grape harvest takes place in the vineyards. Crowds drop noticeably once school starts again. In the high mountains, snow can return as early as October and close some roads.
- Pros: mild climate, colorful forests, fewer crowds, lower prices
- Cons: shorter days, cool nights in Transylvania, sea too cool for most swimmers
- Our tip: September for a full circuit of Transylvania
Winter (November to March): Christmas, skiing and cities
Winter is cold: about 3 °C (37 °F) in the afternoon in January in Bucharest and less than 1 °C (34 °F) in Cluj-Napoca, with nights below 0 °C (32 °F). Snow is frequent in Transylvania and the mountains. It is the season of Christmas markets (Sibiu, Bucharest, Brașov) and of skiing in the resorts of the Prahova Valley, such as Sinaia or Poiana Brașov. High-altitude roads and some trails are then closed.
- Pros: Christmas markets, skiing, low prices in January–February, snowy towns
- Cons: cold, short days, Black Sea and delta dormant
- Who is it for? An urban stay, a Christmas weekend in Transylvania or a ski trip

Bucharest and the southern plain
Bucharest is the hottest city in the table in summer (more than 30 °C (86 °F) in the afternoon in July–August). The best windows are April–June and September–October. In winter, the city remains visitable, with its museums and Christmas market.
Transylvania and the Carpathians
On the Transylvanian plateau, Sibiu and Cluj-Napoca are cooler than Bucharest: about 27 °C (81 °F) in the afternoon in summer and harsher winters (0.9 °C (34 °F) average high in January in Cluj). June and July are the wettest months there, with thunderstorms. For the medieval towns, aim for May to October; for high-altitude hiking, June to September. The Transfăgărășan road is open only part of the year, generally in summer and early autumn, depending on snow cover: check that it is open before you go.
The Black Sea and the Danube Delta
Constanța is the driest resort in the table, with less than 50 mm (2.0 in) of rain a month all year. The sea tempers extremes: summer is a little less hot than in Bucharest and winter milder. The beach season runs from late June to early September. The Danube Delta, further north, is explored by boat from May to September; spring is the best time for birds. Bring mosquito protection.
Maramureș and Bukovina
In the north, the villages of Maramureș, with their wooden churches, and the painted monasteries of Bukovina can be visited from May to October. We have not included normals for these regions, which are cooler than the plain and close to the Ukrainian border: the UK FCDO (GOV.UK, updated 18 September 2026) notes widespread military activity in neighboring Ukraine and refers readers to its Ukraine travel advice.

When to book your trip to Romania
For a circuit in May, June or September, book flights, rental car and accommodation 1 to 3 months ahead. For the Black Sea in July–August and for Christmas market weekends, allow 2 to 4 months. In winter, outside the holidays, you can book late. Bucharest is the main international gateway; other airports, such as Cluj-Napoca or Sibiu, can be more convenient for Transylvania.
Planning your trip to Romania
- Entry requirements: see our page with the entry requirements for Romania.
- Time difference: Romania is on Eastern European Time (UTC+2, UTC+3 in summer): 2 hours ahead of London and usually 7 hours ahead of New York.
- Currency: the Romanian leu (RON); Romania does not use the euro. Check the rate with our currency converter.
- Health: the UK FCDO (GOV.UK, updated 18 September 2026) says UK travelers need a GHIC or EHIC for medically necessary state healthcare, which is not an alternative to travel insurance, and advises insurance covering local treatment and medical evacuation. The U.S. State Department (travel.state.gov, last updated November 12, 2025) notes that U.S. Medicare/Medicaid does not apply overseas.
- Car: you must pay a road toll (rovinieta) to use the national roads; buy a vignette at border points and at most petrol stations (GOV.UK, updated 18 September 2026).
