Grenoble feels like “Europe's chip and big-science cluster on a flat valley floor, three mountain ranges deep — and France's steepest property tax”, while Rouenis “Normandy's capital an hour from Paris — Europe's biggest grain port, a thousand half-timbered houses, and a Seveso ring you learn the sirens for”. Climate is a real differentiator: Grenoble — semi-continental in a mountain valley — cold winters with temperature inversions that trap the air, hot still summers, and a sharp short spring and autumn. Rouen — oceanic — mild damp winters, moderate summers, and rain spread evenly across the year rather than concentrated. grey more often than cold.
