Here is an excellent post from another expat about Sardinian’s weather throughout the year with average monthly climate (temperature, sunshine hours and precipitation average)
When is the best time to visit Sardinia?.
I noticed a few changes the last couple of summers : less people on the beach and on the road in July & August. Bad for tourism overall but great for the people who do come here !
Update : we are now early June and the beaches are virtually empty weekdays still… We shall see what July and August bring …
