Coastal weather Sardinia (Meteo costiero Sardegna)

Influence of the sea

The weather in Sardinia is strongly influenced by the Mediterranean Sea. The island has a typical Mediterranean climate with mild, humid winters and hot, dry summers. The proximity to the sea ensures moderate temperatures, especially on the coast. The water acts as a buffer, cushioning the temperature fluctuations.

The cooling breezes from the sea can have a significant impact on the weather along the coastline. In summer they bring pleasant relief from the heat and in winter they prevent extreme cold. This phenomenon is particularly noticeable along the north and east coasts.

Microclimate on the beaches

A special microclimate often develops along the kilometres of beaches in Sardinia. The reflective effect of the sand and the presence of rocks can lead to localised temperature differences.

Mountain weather Sardinia (Meteo montano Sardegna)

Influence of the terrain

Due to the altitude, temperatures in the mountains tend to be cooler than on the coast. In addition, clouds and fog can form more frequently at higher altitudes, which can restrict visibility.

The mountains also offer protection from strong winds, so it can be less windy at higher altitudes than on the coast. However, winds on mountain peaks can be very strong and sudden, which hikers and climbers should be aware of.

Activities in the mountains

Despite potential weather differences, the mountainous terrain offers a wide range of outdoor activities such as hiking, climbing and mountain biking. However, it is important to note that the weather can change quickly, especially in the mountains.

Influence of the Mistral wind

The Mistral wind plays an important role in the Alghero climate. This north-westerly wind can occur all year round and provides pleasant cooling on hot days, especially in the summer months. It also brings clear air, which improves visibility and makes swimming by the sea even more pleasant.

Cagliari weather (Meteo Cagliari)

Current weather

The weather in Cagliari is known for its warm, dry summers and mild, humid winters. The average temperature in July, the hottest month of the year, is a pleasant 28°C. In January, on the other hand, the temperature drops to a mild 12°C. Rainy days are rather rare in summer, while precipitation is more frequent in winter.

Sardinia is characterised by the significant presence of the Mediterranean climate. This means hot and dry summers and mild and rainy winters. However, there are also local differences due to the island’s topography.

The coastal regions typically experience a Mediterranean climate with warm to hot weather in summer and mild temperatures in winter. In contrast, the mountain regions can be cooler and even experience snowfall.

Best time to visit

The best time to enjoy the weather in Sardinia is usually between May and September.

Olbia weather (Meteo Olbia)

Cloud cover in Olbia

The weather in Olbia can sometimes be cloudy, especially in autumn and winter. The clouds can cover the sky and hide the sun. On such days it could be cool and damp.

However, sometimes the clouds also bring pleasant temperatures. When the sun is hidden by the clouds, it doesn’t get too hot, which can be more comfortable for some people.

Effects on activities

Cloud cover has various effects on activities in Olbia. For example, tourist activities such as beach visits or boat trips could be affected by the cloudy conditions. Taking photos of landscapes is also different under cloudy skies than on sunny days.

On the other hand, outdoor activities such as hiking or cycling could be more enjoyable in cloudy weather as the temperatures are not too high and there is less worry about sunburn.

Sea temperatures Sardinia (Temperature del mare Sardegna)

Average sea temperatures

Sea temperatures in Sardinia are pleasantly warm in summer, averaging around 24 to 26 degrees Celsius. In July and August, the temperature often rises to 28 degrees Celsius. These water temperatures make the Sardinian beaches ideal for water sports such as swimming, diving and snorkelling.

Sultry days in Sardinia (Giorni afosi Sardegna)

The weather in Sardinia

Sardinia’s climate is generally Mediterranean, characterised by hot, dry summers and mild, wet winters. However, during the summer months, particularly in August, the island experiences sultry or muggy days. This means that the air becomes heavy and humid due to high temperatures and moisture levels.

The combination of heat and humidity can make it uncomfortable for people outdoors. The increased moisture in the air makes it harder for sweat to evaporate from our skin, which is our body’s way of cooling down. As a result, we might feel sticky and find it difficult to cool off even with a breeze.

During these afosi giorni, or muggy days on Sardinia, it’s important to take precautions to stay comfortable and safe. For example:

  • Drink plenty of water to stay hydrated.
  • Seek shade or stay indoors during the hottest part of the day.
  • Wear lightweight and breathable clothing.

Planning Activities

When planning activities on tomorrow (the next day) during humid days in Sardinia, consider opting for indoor attractions such as museums or historical sites with air conditioning. Alternatively, you could plan outdoor activities either early in the morning or later in the evening when temperatures are cooler.

It’s also wise to adjust your pace when exploring outdoor attractions.

Wind speed in Sardinia (Velocità del vento Sardegna)

Wind in Sardinia

Sardinia is known for its strong winds. The island is influenced by various winds, including the Mistral, a cool north-westerly wind, and the Scirocco, a warm south-easterly wind. These winds bring different weather conditions with them.

Wind speeds in Sardinia vary depending on the region and time of year. The winds can be particularly strong on the north coast, while milder conditions tend to prevail inland or on the south coast.

The gusty winds can make sailing and surfing a favourite activity as they create ideal conditions for water sports. Due to the constant wind, the island is also well suited for hang gliding and paragliding.

Effects of the wind

The constant wind also has an impact on the island’s vegetation and landscape. Trees often grow in unusual shapes or lean in the direction of the prevailing wind.

Daylight hours Sardinia (Ore di luce diurna Sardegna)

Sunshine and activities

Sardinia, the second largest island in the Mediterranean, is known for its long daylight hours.
