Liège

Climate Characteristics of Liège

General Overview

Liège features a temperate oceanic climate with slight continental influences due to its location in eastern Belgium. The city experiences humid weather throughout the year, but because of its relative proximity to the Ardennes hills, temperatures can be slightly more extreme than in coastal cities – slightly warmer in summer and colder in winter.

Summer Season and Warm Months

Summer in Liège is pleasant and warm. Daytime temperatures range from 22°C to 24°C (72-75°F), making it the best time to enjoy the promenades along the Meuse River. Despite the warmth, summer rains and thunderstorms are a common sight, especially in the late afternoon and evening.

Winter Season and Precipitation

Winter in Liège is cool and grey. Daytime temperatures average around 6°C (43°F), with nighttime lows near 0°C (32°F). Due to its eastern location, the city is more exposed to cold air from central Europe, making snow and frost events slightly more frequent here than in Brussels or Antwerp.

Transition Seasons and Special Phenomena

Transition seasons in Liège are marked by frequent weather changes. Spring brings gradual warming but is very volatile, while autumn features heavy morning fogs over the Meuse and an increase in rainy days. The city's valley topography occasionally leads to cold air trapping in the mornings.
