July-August

July and August in Sardinia are characterized by heat and heavy crowds. Average highs this time of year hover in the mid-80s, but coastal breezes make the temps bearable. Still, visitors will be vying for space on the island's most popular beaches with other tourists, so it's smart to stake out a spot early in the day. Keep in mind that accommodation rates will be the highest during these two months. With this too, it's important to book as early as you can because accommodations tend to fill up quickly in high season. If you plan to use the ferry as your mode of transportation between mainland Italy and the island, you'll also want to book your tickets well in advance – fares sell out fast during peak season.

September-October

September and October enjoy average high temps declining from their summertime highs into the lower 80s and then 70s. Summer's tourists have departed, leaving the island's top attractions less crowded. Plus, the waters should still be warm enough to swim. By October, the accommodation rates will decline from their summertime highs.

November-March 

The months that span November and March are characterized by temperatures that range from the 40s to the 60s.

What's more, room rates will be at their most affordable.
