The best months to visit Sardinia are May, June, July, and September. You will enjoy an average temperature of 26 degrees. August is the warmest month on the island. Also, keep in mind that it can be busier during this month: the Italians are on holiday then as well. Sardinia is a very popular holiday destination for them too.
