The claim "The sky in Brussels is grey" is a general characterization of Brussels' weather, made in the context of Farage describing his distaste for visiting the city. While inherently somewhat subjective, it is well-supported by climate data. Brussels has a temperate oceanic climate with frequent overcast skies, particularly in winter. According to Weatherspark, December — the month of the interview — is the cloudiest month of the year in Brussels, with skies being overcast or mostly cloudy 73% of the time. The cloudier part of the year runs from mid-October to late March. WeatherAPI data shows that in December 2011, Brussels had only about 96 sunshine hours across the entire month (roughly 3 hours per day), with 11 rain days. Travel and weather sources routinely describe Brussels as having grey skies and frequent overcast conditions — one tourism site notes "expect grey skies and damp weather during your visit" and another refers to the "Brussels Grey" as a known local phenomenon. The statement is obviously a generalization — Brussels does have blue-sky days, especially in spring and summer — but as a broad characterization, particularly in early December when the interview took place, it is accurate. The claim captures a well-documented and widely recognized feature of Brussels' climate.
