Winters, from December to February, are quite mild but cool, with average temperatures around 3-5°C. Spring and autumn are pleasant transitional periods with moderate temperatures. A characteristic feature of the climate in Liege is the significant number of days with precipitation throughout the year – from 12 to 19 "wet days" per month, while the total rainfall in millimetres remains low (2-3 mm). This indicates frequent, but usually light rains.

Thus, when planning a trip to Liege, it is recommended to be prepared for the likelihood of precipitation at any time of the year. A light raincoat or umbrella will be useful accessories. The most comfortable weather for walking and sightseeing usually sets in from late spring to early autumn, however, the city has its own charm in other seasons too, if one prepares properly for the weather conditions.

In Liege, as in many parts of Belgium, precipitation falls quite evenly throughout the year, so there is no distinct rainy or dry season here. The weather can be changeable, and light rain is possible in any month. A characteristic feature is not so much the volume of precipitation, which remains low, but its frequency. Travellers should be prepared for possible precipitation and carry an umbrella or raincoat regardless of the season.

The highest number of rainy days occurs during the winter period. December is the absolute leader in terms of precipitation frequency, counting on average 19 wet days, followed by January with 17 days. Given the low winter temperatures, precipitation may fall in the form of light snow or sleet. The "driest" months in terms of rain frequency are June, July, and September, each averaging 12 days with precipitation. In spring and autumn, the weather remains changeable: the number of rainy days ranges from 13 in April and May to 15 in October and November.

When planning a trip to Liege, it is important to consider the changeable weather characteristic of Belgium. The key principle when packing your suitcase should be layering. This will allow you to easily adapt to temperature changes throughout the day. Regardless of the season, be sure to take comfortable waterproof shoes, as exploring the city on foot is a pleasure, and rains are not uncommon here. Also, do not forget an umbrella or a light raincoat.

If your trip falls during the winter months (from December to February), when the average temperature ranges from 1°C to 8°C and precipitation is frequent, pack a warm waterproof jacket, sweaters, a hat, gloves, and a scarf. In spring (from March to May) and autumn (from September to November), the weather is milder but still cool, with average temperatures from 3°C to 20°C. During this period, you will need a mid-season jacket, jumpers, long-sleeved t-shirts, and light trousers. In summer (from June to August), it is warmer in Liege, with an average temperature of 13-23°C, but evenings can be cool, and rains are still likely. Therefore, in addition to light clothing such as t-shirts, shorts, and dresses, it is worth taking a light jacket or cardigan. Do not forget sunscreen and a hat for sunny days.

In general, for a comfortable stay in Liege, it is recommended to have clothes that are easy to combine. Jeans or comfortable trousers, several t-shirts, a couple of sweaters or fleece tops, as well as windproof and waterproof outerwear will become your reliable companions. Remember that even in the summer months, the number of rainy days can be significant, so readiness for precipitation is the key to a pleasant journey.
