The climate in Constanta can be described as temperate, with four distinct seasons. Located on the Black Sea coast in Romania, the city is influenced by sea breezes, which somewhat moderate temperature fluctuations compared to inland areas. Tourists can expect warm, and at times hot, sunny summers and relatively mild, cool winters.

The summer months, especially July and August, are the warmest: the average air temperature hovers around 24-25°C, and maximum values can reach 29°C. Winters in Constanta are cool but without severe frosts – in January, the average temperature is about 3.3°C, with night-time lows dropping close to zero. Spring and autumn are comfortable transitional seasons with gradual temperature changes. A characteristic feature of the local climate is the relatively low level of precipitation throughout the year. Although rainy days occur regularly (from 4 to 10 days per month), the amount of precipitation is usually small, amounting to just 1-2 mm per month.

The climate in Constanta is characterized by noticeable seasonal temperature changes. The hottest month is usually August, when the average daily temperature reaches 29.1°C, and the monthly average is 24.6°C. July follows closely behind with an average maximum of 28.6°C. The coldest month is considered to be January, with an average temperature of 3.3°C and night-time lows dropping on average to 0.3°C, making it the coolest period of the year.

The summer months in Constanta, from June to August, offer truly warm weather. Daytime temperatures during this period confidently stay in the range from 25.9°C in June to a peak of 29.1°C in August, creating ideal conditions for a seaside holiday. Nights also remain warm, with average minimum values from 17.5°C to 20.1°C, allowing you to enjoy evening walks without extra warm clothing. The difference between day and night temperatures in summer is about 8-9°C, bringing a pleasant sense of freshness after a sultry day.

Winter in Constanta, covering December, January, and February, is cool but generally mild, without severe and prolonged frosts. Average daily maximums in the winter months vary from 6.3°C in January to 8.4°C in February. Night-time temperatures drop to marks around 0.3°C - 2.5°C, indicating the possibility of night frosts, but rarely leading to extreme cold. Spring and autumn are characterized by gradual temperature changes, offering comfortable weather for excursions and exploring the city when there is neither summer heat nor winter chill.

In Constanta, a relatively small amount of precipitation is observed throughout the year. Monthly averages are extremely low, varying from just 1 to 2 mm, indicating predominantly dry conditions in the city.

Despite the low total volume, periods with more frequent precipitation can be distinguished. The highest number of days with precipitation falls in June (about 10 days), and precipitation is also relatively frequent in April, May, and December (an average of 9 days each). The driest month is August, when precipitation falls on average for only 4 days. There is no clearly defined rainy season in terms of volume, but late spring, early summer, and early winter are characterized by a higher probability of encountering rainy or snowy weather.

Given the low average temperatures in the winter months, especially in January (average minimum 0.3°C) and February (average minimum 1.5°C), precipitation during this period may fall as snow. The rest of the year, it is usually light rain or drizzle, as the total amount of precipitation remains insignificant. The highest amount of precipitation, albeit small (only 2 mm per month), is recorded in June, July, November, and December, while in other months, only 1 mm falls.

When planning a trip to Constanta, it is important to consider seasonal weather changes to pack your suitcase correctly. Summer (June-August) is warm here, with average temperatures reaching 24-29°C. At this time, you will need light clothing, swimwear, a hat, sunglasses, and sunscreen. However, even in summer, precipitation is possible (on average 4-10 rainy days per month), so a light windbreaker or raincoat may come in handy. Evenings can be a bit cooler, especially by the sea, so a thin sweater or cardigan will not be amiss.

Spring (March-May) and autumn (September-November) in Constanta are characterized by changeable weather. Temperatures range from 6°C in March to 20°C in May and September, dropping to 9°C in November. During these periods, layered clothing works best: T-shirts, shirts, sweaters, and a light jacket or raincoat. Don't forget an umbrella or raincoat, as the number of rainy days varies from 5 to 9 per month, although the total rainfall is low. Winter (December-February) is quite mild, with average temperatures around 3-5°C, but sometimes dropping to 0-1°C. A warm jacket, hat, scarf, gloves, and waterproof shoes will be necessary. Although severe frosts are rare, it is worth being prepared for cool and damp weather with possible precipitation.

Regardless of the season, comfortable shoes for walking around the city and along the coast are a mandatory element of your luggage. Given the small but regular amount of precipitation throughout the year, a compact umbrella or light raincoat will always be useful. The principle of layering in clothing will allow you to feel comfortable with any weather changes during the day, especially in the transitional seasons.
