Well, they say is Madrid nueve meses de invierno y tres de infierno. This is clearly not the case for Cagliari where the average for June is 28° / 17° (day / night). By the way, in addition to having fewer crowds, Cagliari is almost equidistant to Palma as Madrid, it is also on an island and it is on the coast of the same sea. Would you go to Palma for a Sunday in late June as a Madrileņo?
