The climate in Dalian can be characterized as a temperate monsoon climate with four distinct seasons. The city is influenced by a maritime climate, which softens both the summer heat and winter cold compared to continental areas. Overall, the weather here is quite comfortable for visiting at various times of the year, but each season has its own unique features.

Summer in Dalian, from June to August, is warm and humid, with average temperatures reaching 25.6°C in August.

Winter, from December to February, is cool, with average temperatures around -1.8°C in January and minimal precipitation. Spring (March-May) and autumn (September-November) are transitional seasons with pleasant weather. In spring, the temperature gradually rises, while autumn delights with comfortable warmth and less rain compared to summer.

A distinctive feature of Dalian's climate is the noticeable difference between seasons: from a cool and dry winter to a warm and more humid summer. The amount of precipitation is generally low, making the city attractive to visit; however, it is worth noting the increase in the number of rainy days during the summer months, especially in August.

Dalian experiences significant annual temperature variations, reflecting the change of four seasons. The coldest month is January, when the average temperature drops to -1.8°C, with daily lows reaching -3.9°C and highs barely exceeding zero (0.3°C). Conversely, the peak heat occurs in August, which is the hottest month with an average temperature of 25.6°C. In August, daily highs average 27.1°C, while nightly lows remain at a comfortable 24.1°C.

The summer months in Dalian, from June to August, are characterized by steady warmth. In June, the average temperature is 20.7°C (minimum around 19.0°C, maximum up to 22.5°C), and in July it rises to 24.8°C (ranging from 23.4°C to 26.3°C), reaching its peak in August. Winter, covering December, January, and February, is quite cool. In December, the average temperature is 0.5°C (from -1.7°C to 2.6°C), and in February it is slightly warmer than in January, with an average temperature of -0.7°C (from -2.7°C to 1.3°C). Winter temperatures consistently stay around or below the freezing point, especially at night.

Spring and autumn months are transitional periods with more moderate temperatures. In spring, from March to May, there is a gradual warming: from an average of 4.5°C in March (minimum 2.5°C, maximum 6.5°C) to 15.5°C in May (minimum 13.7°C, maximum 17.4°C). In autumn, from September to November, the temperature smoothly decreases: from a comfortable 21.9°C in September (minimum 20.3°C, maximum 23.6°C) to 8.0°C in November (minimum 5.8°C, maximum 10.2°C). A feature of Dalian's climate is the relatively small difference between daytime maximum and nighttime minimum temperatures throughout the year. This daily range is usually about 3-4.5°C, indicating the moderating influence of the sea and the absence of sharp temperature fluctuations between day and night.

Dalian sees a rather uneven distribution of precipitation throughout the year, with a distinct, though not very intense, peak in the summer months and a very dry winter period. Overall, the city is not characterized by heavy rainfall, but its frequency and nature change depending on the season.

The highest amount of precipitation falls in summer, especially in July and August. August is the wettest month, with an average of 5 mm of precipitation and about 12 rainy days recorded. July also sees increased humidity with 4 mm of precipitation and approximately 9 rainy days. Summer precipitation usually comes in the form of rain, possibly as short showers given the warm season.

The winter months—December, January, and February—are the driest. During this period, the average monthly precipitation is 0 mm, indicating extremely insignificant or absent measurable precipitation. Despite this, there are about 3 days with precipitation in January, 2 days in February (the lowest figure of the year), and 4 days in December. Given the negative or near-zero average temperatures in these months (from -1.8°C in January to 0.5°C in December), any precipitation is likely to fall as light snow or frost.

Spring (March-May) and autumn (September-November) months are transitional. Precipitation amounts during these periods are low, ranging from 1 to 2 mm per month. The frequency of days with precipitation gradually increases in spring, from 3 days in March (1 mm) to 7 days in May (2 mm). In autumn, the amount of precipitation and rainy days decreases: September sees 2 mm of precipitation over 6 days, while October and November see 1 mm over 5 days respectively. Precipitation in these seasons usually comes as light rain.

When planning a trip to Dalian, it is important to consider its four distinct seasons, each dictating its own clothing style. In winter (December-February), when average temperatures hover around zero (from -1.8°C to 0.5°C) and can drop lower, you will need warm clothes: a winter jacket (preferably wind- and waterproof, as it can be windy), sweaters, perhaps thermal underwear, a hat, gloves, and a scarf. Although there is practically no precipitation in winter (0 mm), several "wet days" are recorded, which may mean light snow or frost, so waterproof shoes would be useful. In summer (June-August), Dalian is warm and humid, with average temperatures reaching 25.6°C in August. This is also the period with the highest number of rainy days (up to 12 in August), although the volume of precipitation is low (2-5 mm). Pack light, breathable clothing made of cotton or linen, t-shirts, shorts, summer dresses, as well as sunscreen, a hat, and sunglasses. Don't forget an umbrella or a light raincoat.

Spring (March-May) and autumn (September-November) are pleasant transitional seasons with moderate temperatures, but the weather can be changeable. In spring, the temperature gradually rises from a cool 4.5°C in March to a comfortable 15.5°C in May, while in autumn it smoothly decreases from 21.9°C in September to 8.0°C in November. During these periods, the layering principle works best: t-shirts, long-sleeved shirts, light sweaters or fleece jackets, as well as a windbreaker or mid-season jacket. Precipitation in these seasons is infrequent (1-2 mm per month), but a small umbrella may still come in handy, as rainy days do occur (from 3 to 7 per month). Regardless of the season, comfortable walking shoes are an absolute necessity for exploring Dalian and its surroundings. A small backpack for day walks and excursions will also be useful.
