What October feels like

October is two seasons in one. Early in the month you can still swim on the right afternoon; by the end, the first big rains have greened the island and the season has visibly turned. This is when Autunno in Barbagia opens village courtyards across the mountains, chestnuts and new wine appear, and walking weather returns in full. Pack layers and an appetite. Around Cagliari and the Campidano the capital anchors everything, with Poetto's long beach and the south coast an easy reach away.
