Seasonal Variations in Rainfall

The seasonal variations in rainfall are influenced by several factors, including the position of Cagliari on the southern coast of Sardinia, which is exposed to the Mediterranean Sea. During the summer months, the Mediterranean Sea is warm and produces moist air that can lead to thunderstorms and occasional heavy rainfall. However, the summer months are generally characterized by clear skies and little precipitation. In the winter months, the Mediterranean Sea is cooler and produces less moisture, resulting in less frequent rainfall. Additionally, Cagliari is located in a region that is affected by the westerlies, which bring moist air and can produce rainfall throughout the year. The combination of these factors results in the distinct seasonal rainfall patterns observed in Cagliari.

Historical Occurrences

Snowfall in Cagliari, Italy, is a rare and remarkable phenomenon. Historically, snow has been recorded on several occasions in the city, but these events are infrequent and often fleeting. The most significant snowfall occurred in February 1956, when a thick blanket of snow covered the city, paralyzing transportation and disrupting daily life. Other notable snowfall events have occurred in 1985, 2012, and 2018, each with varying degrees of accumulation.

Causes and Conditions

The occurrence of snowfall in Cagliari is attributed to a combination of cold air and moisture. When cold air from the north or northeast meets moisture in the atmosphere, it can lead to the formation of snow. In the case of Cagliari, these conditions are occasionally met during the winter months, particularly when a cold front from the Balkans or Eastern Europe coincides with moist air from the Mediterranean Sea. As the cold air descends over the city, it encounters the warmer air from the sea, causing the moisture to condense and form snowflakes.

Summer Sunshine in Cagliari

Cagliari, the capital of Sardinia, Italy, boasts an idyllic Mediterranean climate, with long, sunny summers and mild winters. During the height of summer, from June to September, the sun reigns supreme, casting a warm glow over the city and its surroundings.

Seasonal Humidity Variations

Cagliari, Italy experiences significant variations in humidity throughout the year. During the cold winter months (December to February), the relative humidity often exceeds 80%, creating a damp and muggy atmosphere. As spring arrives (March to May), the humidity levels gradually decrease, reaching their lowest point during the hot summer months (June to August). Summertime in Cagliari is characterized by relatively low humidity, typically ranging between 50% and 65%. This drop in humidity is primarily due to the prevailing northwesterly winds, known as the Maestrale, which bring in drier air from the sea.

Impact on Climate and Comfort

The high humidity levels during winter can make the cold weather feel even colder, as the moisture in the air acts as an insulator, trapping body heat. Conversely, the low humidity in summer can contribute to the perception of heat, as the body’s natural cooling mechanisms are less effective in removing sweat. This combination of high winter and low summer humidity creates a distinct climate in Cagliari, with the winters being ощутимо colder than they would be otherwise, and the summers feeling hotter. Additionally, the high humidity in winter can lead to condensation on windows and walls, potentially causing mold and mildew growth.

Wind Patterns and Intensity

Cagliari, Italy, is characterized by a Mediterranean climate, influenced by the prevailing westerly winds from the Atlantic Ocean. During the summer months, the northwesterly Mistral wind brings cool, dry air, while the Scirocco from the southeast brings warm and humid air from Africa. In winter, the northwestern Tramontana strengthens, bringing strong gusts and cold conditions. The mean wind speed in Cagliari ranges from 15 to 20 kilometers per hour (9-12 miles per hour) throughout the year. However, extreme wind events, such as squalls or strong gusts, can occur during localized weather conditions.

Seasonal Variations

The wind patterns and intensity in Cagliari exhibit seasonal variations. In spring (March-May), the wind speeds are typically moderate, with occasional strong gusts. The summer months (June-August) bring the most consistent winds, with the Mistral dominating and providing relief from the warm temperatures. In autumn (September-November), the wind becomes more variable, with both the Mistral and Scirocco influencing wind conditions. During winter (December-February), the Tramontana strengthens, bringing harsher winds and cold temperatures. The strongest winds occur during the transition months of March and November, when the wind direction changes rapidly and can reach speeds of up to 60 kilometers per hour (37 miles per hour) or more.
