Climate and Weather in Trieste, Italy

Trieste is a beautiful coastal city located in northeastern Italy, near the border with Slovenia. It is characterized by its unique climate, influenced by both its proximity to the Adriatic Sea and its position at the foot of the Slovenian Alps. The city enjoys a Mediterranean climate, with mild winters and warm summers, making it a popular destination for tourists throughout the year.

Temperature

The average annual temperature in Trieste is around 15 degrees Celsius (59 degrees Fahrenheit). Summers are generally warm, with average temperatures ranging from 24 to 28 degrees Celsius (75 to 82 degrees Fahrenheit).

Winters are mild, with average temperatures ranging from 5 to 10 degrees Celsius (41 to 50 degrees Fahrenheit). The coldest month is January, with temperatures rarely dropping below freezing.

However, it is worth noting that Trieste experiences a unique weather phenomenon known as the "bora." The bora is a strong, cold wind that blows from the northeast, particularly during the winter months. It can bring gusts of wind reaching up to 200 kilometers per hour (124 miles per hour) and significantly lower temperatures, making the air feel much colder than the actual temperature. The bora can last for several days and can have a significant impact on the local weather conditions.

The wettest months are October and November, while the driest months are July and August. During the summer months, rainfall is relatively low, and the weather is mostly dry and sunny. On the other hand, the autumn months can be quite rainy, with occasional heavy downpours.

The proximity to the Adriatic Sea also influences the local weather patterns, as the city can experience occasional thunderstorms, especially during the summer months. These thunderstorms can bring heavy rain, strong winds, and lightning, but they are usually short-lived.

Sunshine

Trieste enjoys a good amount of sunshine throughout the year. On average, the city receives approximately 2,000 to 2,100 hours of sunshine annually. The sunniest months are July and August, with an average of 10 to 11 hours of sunshine per day. However, even during the winter months, Trieste still benefits from a reasonable amount of sunshine, with an average of 4 to 5 hours per day.

Seawater Temperature

Being a coastal city, Trieste offers the opportunity for visitors to enjoy the refreshing waters of the Adriatic Sea.

During the winter months, the seawater temperature drops to around 10 to 12 degrees Celsius (50 to 54 degrees Fahrenheit). Therefore, swimming in the sea is more pleasant during the summer season.

The city benefits from a Mediterranean climate, with the Adriatic Sea playing a significant role in shaping its weather patterns. Visitors can expect pleasant temperatures during the summer months, while winters are generally mild, with occasional cold spells brought by the bora wind.
