Dublin's climate is classified as a temperate maritime type, which means there are no sharp temperature fluctuations throughout the year. Winters here are mild, and summers are pleasant and not too hot. A characteristic feature of the weather in the capital of Ireland is its variability, so tourists are advised to be prepared for surprises and carry clothing for various occasions.

Four seasons can be distinguished in Dublin. Winter (December-February) brings average temperatures around 5-6°C. In spring (March-May), the air gradually warms up, and average temperatures range from 7°C to 12°C. Summer (June-August) is the warmest time of the year with averages of 14-16°C, making it comfortable for walking. In autumn (September-November), the temperature gradually decreases from about 14°C to 8°C, creating a cozy atmosphere for visiting sights. It is important to note that rainfall is a frequent visitor in Dublin year-round: the number of rainy days per month varies from 12 to 17, which gives Ireland its famous emerald colour.

The temperature regime in Dublin is characterized by moderation and a lack of extremes. Throughout the year, the average temperature ranges from approximately 5.4°C in January, which is the coldest month, to 15.8°C in July, traditionally the warmest month. August is also characterized by warm weather with an average temperature of 15.6°C. Thus, the annual amplitude of average temperatures is not very large, which is typical for the maritime climate of Ireland.

The summer months in Dublin, from June to August, offer pleasant warmth, ideal for walking and exploring the city. Average maximum temperatures during this period reach 17.6°C in June, 18.9°C in July, and 18.6°C in August. Nights remain cool, with average minimum temperatures around 11-13°C. This means that even on the warmest days, evenings can be fresh, so a light jacket or sweater will be very useful.

Winter in Dublin, covering December, January, and February, is quite mild. Average temperatures in these months range from 5.4°C to 6.4°C. Daily highs usually stay within 7.6°C - 8.8°C, and nightly lows rarely drop significantly below 3-4°C, making severe frosts a rarity. Temperature fluctuations between day and night in Dublin throughout the year are small: the difference between the average maximum and average minimum temperature is usually between 4°C and 7°C, providing fairly stable temperature conditions throughout the day.

In Dublin, precipitation is a frequent companion of the weather throughout the year, however, according to statistical averages, it is rarely heavy. The city does not experience a clearly defined rainy season or a prolonged dry period in the classical sense of these terms. A characteristic feature is the frequent occurrence of precipitation, but in small amounts, which is typical for the maritime climate of Ireland.

Speaking of frequency, the highest number of days with precipitation is usually recorded in March – on average 17 days. In this month, as well as in August, September, October, November, and December, the average monthly rainfall is about 3 mm. The lowest total amount of precipitation – on average just 2 mm per month – falls in January, February, April, May, June, and July. Despite such a small volume, the number of rainy days even in these months remains significant, varying from 12 days in January to 15 days in July. This indicates that rain in Dublin most often presents as light drizzle or brief weak precipitation, rather than heavy downpours.

Thus, although rainy weather can be expected in Dublin in practically any month, the intensity of this precipitation is generally low. Snow, given the mild winter temperatures (average minimum in January is +3.3°C) and very low total precipitation figures, is not a characteristic phenomenon for the city. Travellers are advised to carry an umbrella or raincoat, as light rain can start at any time, contributing to the preservation of Ireland's famous emerald greenery.

When packing your suitcase for a trip to Dublin, be prepared for the famous changeable Irish weather. The tourist motto here is "four seasons in one day," so layering your clothes will be your best friend. Essential items at any time of the year include a waterproof and windproof jacket, preferably with a hood, as wind often accompanies precipitation. Also extremely important is comfortable water-resistant footwear for walking on cobblestones and in parks, as it rains often here, although usually not heavily. A small folding umbrella may be useful, but in windy weather, a jacket with a hood will be more reliable.

In the warm season, roughly from May to September, when average temperatures range from 11°C to 16°C, pack T-shirts, long-sleeved shirts, light jumpers or fleece jackets, and trousers. Even on summer evenings, it can be fresh, so an extra layer of clothing will not hurt. Sunscreen will also come in handy, as the UV index can be high even on cloudy days. In the cold period, from October to April (average temperatures from 5°C to 10°C), you will need warmer items: sweaters, warm trousers, thermal underwear (especially if you are sensitive to cold), as well as a hat, a scarf, and gloves. The main thing is that your outerwear should protect well against wind and moisture, as it is often windy in Dublin, which increases the feeling of cold.
