The Maestrale and Granite: What Is the Climate Like in Olbia?

---

Olbia is located on the northeastern coast of Sardinia in a sheltered bay, surrounded by the granite mountains of Gallura. The climate is Mediterranean, with mild, humid winters and hot, dry summers. From December through February, daytime temperatures range from 14 to 15 degrees; at night, the thermometer drops to an average of 5 degrees in January and February; frost is rare along the coast. In July and August, the long-term average high is 32 degrees, though it can get significantly hotter when the wind is from the east. The prevailing wind is called Maestrale: a northwest wind that blows in from the open Mediterranean and becomes strong in gusts. It keeps the air clear, creates the famous sailing conditions off the Costa Smeralda, and is the reason why the granite cliffs of Gallura have been carved into their bizarre shapes. The east coast around Olbia, however, lies in the lee of the island and is therefore calmer than the west and north coasts. Annual precipitation is around 525 millimeters, concentrated from October through March; November is the wettest month, with just under 87 millimeters; summer is practically rain-free. The data in the climate table comes from the station at the Olbia-Costa Smeralda Airport on the southeastern outskirts of the city.

The swimming season runs from late May to early October, with the warmest water temperatures in August and September.

In July and August, the Costa Smeralda is at its busiest. Spring and fall are ideal for hiking in Gallura and exploring the granite landscape around Monte Limbara. Winter is mild, windy, and very quiet; many businesses along the coast close. Day trip destinations throughout the island are listed in the Sardinia Travel Guide, for dates, see Top events in Italy and select hotels at Top Hotels in Italy.
