Question 1

What is the best month overall?

Accepted Answer

For the best balance of warm sea, low crowds, and prices: the second half of June or September. For the absolute warmest sea: August. For snorkeling with maximum visibility: late May and June.

Question 2

When is it most likely to find the mistral?

Accepted Answer

The mistral can blow all year round, with more frequent gusts in spring and autumn. In summer, it usually lasts 1-3 days: excursions adapt by sailing in sheltered areas, and the Gulf of Olbia remains almost always navigable.

Question 3

Is the sea swimmable in May?

Accepted Answer

Yes, but it's cool: 18-21 degrees. On sunny days, the sheltered and shallow coves (Cala Brandinchi, the pools of Santa Maria) warm up significantly, even from mid-May.

Question 4

When do flights and accommodations cost less?

Accepted Answer

Excluding winter, the best windows are May, the first half of June, and from mid-September onwards: you save 20-40% compared to August on accommodations, car rentals, and ferries.

Question 5

Do excursions work even out of season?

Accepted Answer

From May to October, yes, with a reduced calendar at the edges of the season. From November to March, only occasional trips remain active on sunny weekends: for a trip focused on boat excursions, stick between mid-May and mid-October.
