Weather conditions will change across Romania this weekend, following a period of higher temperatures in several regions. Meteorologists are forecasting cooler weather, rain, torrential showers, thunderstorms and bouts of atmospheric instability, especially in the southwest, centre, northeast and mountains, and temporarily across the eastern half of the country.
For more information from the National Meteorological Administration (ANM), see What will the weather be like in Romania in May 2026: gradual warming, little rain at first and higher temperatures towards the end, which provides additional details on the subject.
The weekend will bring changeable conditions: cool mornings, temporarily cloudy skies, intermittent rain and temperatures that will no longer reach the high values seen in previous days. In some areas, rain may be more intense over short periods, while isolated hail and stronger winds are also possible.
According to the National Meteorological Administration forecast, the weather will turn cooler across most of the country, while atmospheric instability will affect several regions. Highs will generally range between 15 and 24°C on Saturday, while on Sunday they will reach between 16 and 27°C, with significant differences from one region to another.
Weather turns cooler on Saturday across most of the country
On Saturday, 9 May, the weather will begin to cool across most of Romania. Skies will see temporarily heavier cloud cover, while showers will occur during the day in the southwest, centre and northeast of the country. Rain will also be reported in smaller areas of other regions, while overnight instability will be more pronounced across the eastern half of the country.
Rain may be torrential, particularly where vertically developing clouds form quickly. In such situations, substantial amounts of water can accumulate in a short time, potentially causing water build-up on streets, problems in low-lying areas and difficulties for drivers.
High temperatures will range between 15 and 24°C, lower than those experienced earlier in several areas. Lows will range from 7 to 14°C, and fog may form locally in the morning and overnight.
Torrential rain, thunderstorms and isolated hail
Atmospheric instability does not mean only ordinary rain. In some areas, showers may be accompanied by thunderstorms, brief increases in wind and, in isolated cases, hail. Rainfall totals may locally reach 15–25 L/sq m and may exceed 40 L/sq m in places.
Such episodes are typical of transitional periods, when colder air masses move over regions that had previously warmed up. The atmosphere becomes unstable, and clouds can produce rapid, intense rainfall. Although not all localities will be affected in the same way, where storms occur, conditions may be more severe for a short time.
Drivers should be alert to wet road surfaces, reduced visibility and water accumulation. In mountain areas, rain may be accompanied by stronger winds, and conditions can change quickly on hiking trails.
Weather in Bucharest
In the capital, the weather will be cooler than in previous days. There will be temporary cloud cover and showers, while thunderstorms cannot be ruled out. Winds will be light to moderate, and the maximum temperature will be around 21°C.
Overnight, temperatures will fall to around 12–13°C. On Sunday, conditions will become somewhat more settled, but skies will continue to see temporary cloud cover. Light rain may fall early in the day, while showers and thunderstorms will remain possible in the afternoon.
For Bucharest residents, the recommendation is simple: an umbrella or waterproof jacket may be useful, especially for afternoon travel. The weather will not necessarily be cold in a winter sense, but it will be more unsettled and wetter.
On Sunday, rain shifts mainly to the east and the mountains
On Sunday, 10 May, the weather will remain changeable. Skies will be variable, but with cloud cover and rain, mainly in the form of showers, especially across the eastern half of the country and in the mountains. During the afternoon, the likelihood of thunderstorms will be higher in Muntenia, Dobruja, the Eastern Carpathians and the eastern part of the Southern Carpathians.
Highs will range between 16 and 27°C, so some regions will be more pleasant than on Saturday. However, instability will persist, and conditions may quickly alternate between sunny spells and periods of rain.
Overnight, rain may return to the far west of the country. Lows will generally range between 5 and 13°C, with lower values in the depressions of the Eastern Carpathians. Fog may form in limited areas.
Weather remains unsettled in the mountains
Mountain areas will experience bouts of unsettled weather, with showers, wind and lower temperatures. Particularly in the Eastern Carpathians and the eastern part of the Southern Carpathians, rain may occur in the afternoon, while thunderstorms are possible in areas where convective clouds develop.
Visitors heading to the mountains should bear in mind that conditions can change quickly. A hike that begins in sunshine can become difficult if rain, wind or fog develops. Waterproof gear, appropriate footwear and checking the local forecast are essential.
At higher elevations, winds may strengthen, and the temperature felt may be lower than the thermometer reading. Caution is recommended on long hikes, along with avoiding exposed areas during thunderstorms.
Weather on the coast
On the coast, the weather will not be ideal for the beach. Skies may see temporary cloud cover, while light rain or showers may occur especially in the evening and overnight. Winds will be light to moderate, and temperatures will be lower than during a truly summery weekend.
In Dobruja, showers and thunderstorms may occur on Sunday afternoon. Those planning to visit the seaside should take the changeable weather into account and follow weather updates, especially if they intend to spend considerable time outdoors.
What to expect after the weekend
After the weekend, the weather will not settle completely. On Monday, 11 May, instability will be more pronounced across the western half of the country, where showers and thunderstorms are expected. In limited areas, rain may be torrential, and isolated hail may fall.
On Tuesday, 12 May, the weather will turn cooler again compared with the previous day, more markedly in the intra-Carpathian regions. Most of the country will see temporarily heavier cloud cover, showers and thunderstorms. Rainfall totals may be more substantial in isolated areas, while more severe weather conditions may occur in the mountains.
The outlook for 11–18 May indicates above-normal precipitation across most of the country, particularly in mountain areas. This means rainy episodes may continue, even if not every day and not in all regions with the same intensity.
Weekend recommendations
If you have travel plans, check the forecast before setting off. Conditions can change from one hour to the next, especially in areas affected by showers. For long journeys, it is advisable to allow for periods of rain, reduced visibility and more difficult traffic conditions.
For those heading to the mountains, waterproof gear is necessary. Avoid exposed areas during storms and do not continue hiking if thunderstorms develop nearby. For those with activities in town, an umbrella or a lightweight rain jacket may be enough.
In areas where larger amounts of water may accumulate, caution is recommended around basements, car parks, underpasses and roads with poor drainage. Torrential rain can cause rapid water build-up, even if the episode is brief.
Weather conditions will change noticeably across Romania this weekend. Temperatures will fall in much of the country, while rain and atmospheric instability return to several regions. Saturday will bring the more noticeable cooling and more widespread phenomena, while on Sunday rain will be concentrated mainly in the east, the mountains, Muntenia and Dobruja.
This is not an unusual episode for May, but the weather will be unsettled enough that outdoor plans may need to be adjusted. Those travelling, heading to the mountains or going to the seaside should check the local forecast before leaving and be prepared for short-lived but potentially intense rain.
