🇧🇪 Brussels vs 🇭🇰 Hong Kong

Brussels sits in a broad valley carved by the Senne river, with the city climbing from the low-lying lower town (~15m elevation) to the upper town and surrounding plateaus (~100m). This topographic split creates distinct microclimates: the lower town is prone to fog, temperature inversions, and trapped humidity, while the higher southeastern districts enjoy better ventilation and slightly cooler summers. The city's extensive parks and forested edges — particularly the Sonian Forest to the southeast — provide significant cooling corridors, but the dense 19th-century urban core generates a pronounced heat island effect.

Humid subtropical — hot wet summers, mild dry winters, typhoon season

Hong Kong has a dramatic climate shaped by the South China Sea and its mountainous terrain. Winters are mild and dry; summers are brutal with typhoons. The autumn window (October–December) is widely considered the best time to visit.
