Belfast feels like “A UK city in a different legal jurisdiction — Irish citizens need no permission at all, your landlord usually pays the rates, and nobody gets a water bill”, while Portsmouthis “Almost two-thirds of the Royal Navy's surface fleet moors here — on an island so full it is the densest local authority in Britain outside London bar one”. Climate is a real differentiator: Belfast — temperate maritime and very mild, ringed by hills on three sides and a sea lough on the fourth — rain on more days than almost any large uk city, snow rare at sea level, and summer highs that seldom pass 20 °c. Portsmouth — among the mildest, sunniest and driest parts of britain on the solent — but low-lying, exposed and windy, with a coastal flood risk the city plans around.
