Cardiff feels like “A capital with its own parliament, its own property tax and free prescriptions — where you sign an occupation contract, not a tenancy”, 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: Cardiff — temperate maritime and one of the wetter big cities in britain — mild and windy off the bristol channel, with snow rare at sea level and the beacons white an hour behind you. 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.
