🇧🇪 Brussels vs 🇮🇪 Dublin

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.

Temperate oceanic — mild, rainy, windy year-round, no extremes

Dublin's climate is famously wet and mild. It never gets very hot or very cold. Rain is possible any day of the year. Summer brings long twilight evenings; winters are dark and stormy.
