Ruta de la Lana crosses varied climates from the Mediterranean coast near Alicante to the open interior and the northern plateau, so conditions change steadily as the route advances. April and September typically align with milder temperatures, steadier days, and longer light, balancing the warmer south with cooler inland stretches. Outside these periods, the warm season brings strong sun, occasional short storms, and longer dry gaps between towns, while the colder season sees shorter days, more persistent cloud and rain, and the chance of frost, snow, or ice in northern sections.
