🇧🇪 Brussels vs 🇵🇱 Warsaw

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 continental — cold winters, warm summers, variable transitional seasons

Warsaw has a typical Eastern European continental climate. Winters are cold and grey; summers are warm and increasingly sunny. The city sits in the flat Polish Plain with no geographic barriers to arctic air masses in winter or Mediterranean warmth in summer.
