December is a decent shoulder option for Brussels: fewer crowds, some trade-offs. Expect daytime highs around 6°C, nights near 2°C and roughly 13 rainy days across the month. Cold near 6C but at its most festive: the Winter Wonders market and light show spread across the Grand-Place, the Bourse and the Sainte-Catherine quarter through the month. Weekends before Christmas are packed with visitors, so come midweek and expect rain mixed with the cold rather than reliable snow.

December is quieter, which makes it the right month to afford the splurge picks.
Special occasions€€€Rocco Forte by the Grand-Place · Grand-Place and Ilot Sacre
A Rocco Forte five-star on a quiet lane a minute behind the Grand-Place, on the site of a 16th-century prison, with Tintin prints and Flemish art through the rooms. It is the smartest address in the centre, steps from the guildhalls.

Couples€€Boutique by the Bourse · Sainte-Catherine
A small design hotel on Rue du Marche aux Herbes, right by the old stock exchange, the Bourse, a two-minute walk from the Grand-Place. The dark, moody lobby and the central setting make it a handy, characterful base in the middle of Brussels.

With 13 rainy days and highs of 6°C, build your December days around indoor anchors and treat sunny windows as a bonus.
Mont des Arts and Royal Museums of Fine Arts
TipThe terraced Mont des Arts gardens give a free framed view back over the lower town toward the Town Hall spire, and they sit at the door of the Royal Museums of Fine Arts. The combined Old Masters and Magritte Museum ticket is worth a half day for Bruegel, Rubens and the world's largest Magritte collection; book online to skip the desk, and note it closes on Mondays.
Belgian Comic Strip Center
TipHoused in a Victor Horta-designed Art Nouveau warehouse from 1906, this museum traces the Belgian comic tradition from Tintin to the Smurfs. Pair it with the free comic-mural walking route through the centre, where more than fifty painted walls turn street corners into strip panels; the tourist office hands out a map, and the Tintin mural on Rue de l'Etuve is the classic photo.
Sainte-Catherine seafood quarter
TipThe old fish-market quarter around the Sainte-Catherine church is where locals go for oysters, moules and grey shrimp rather than the tout-heavy Rue des Bouchers. Stand-up spots like the long-running Mer du Nord counter serve fresh fish and a glass of white to eat on the pavement; go early evening, as the best kitchens fill up and some shut by mid-evening.
Sablon chocolate quarter
TipThe upscale Sablon square is the address for Belgium's flagship chocolatiers, with Wittamer, founded here in 1910, and Pierre Marcolini's dark boutique both on or beside it. Buy a small mixed box to taste rather than a big one, come on a weekend for the antiques market that fills the square, and step into Notre-Dame du Sablon church next door, which is free.
