Most of the year, the coastline around Trieste enjoys a
mild and sunny climate. In fact, in Trieste it is seldom,
or never, cold and wet at the same time. When the weather is cold,
this is mostly due to the northerly wind, and the air is dry. When
the air is moist, i.e. the southerly wind prevails, the temperature
is mild. In general, October and November are normally the rainiest
months of the year.
Winters are generally mild and sunny. These
pleasant Mediterranean weather conditions are sometimes interrupted
by a very changeable cold weather generated by a northerly wind
called "Mistral" in the French Provence and Bora
on the Adriatic sea. This northerly wind can bring unseasonably
cold weather on the Mediterranean for a few days in winter and
early spring.
The average temperature in wintertime is 8° C, 16° C , in autumn
and 15° C in spring.
Summers are hot and dry. For example, there are
on average 300 sunny days, either entirely or partly sunny, in one
year. With its 2500 hours of sunshine per year, the Trieste
coastline is statistically one of the sunniest spots, not only in
Italy but also in Europe as a whole. Anywhere in Trieste, the sea
is at most a few kilometres away. The mitigating effect of the sea
accounts for an average temperature around 24°C.

Curiosity: "Bora" the cold wind
Derived from "boreas" (Greek: "boréas") the Bora is a
strong northerly wind that hits the Trieste gulf from
EAST-NORTHEAST direction. In town, the bora can attain an average
speed of 50-80 km/h; its strongest gusts may reach a speed of
170-180 km/h. The Bora wind has many names in Trieste, depending on
its force: borin: light bora, tramontana
wind; borineto: tramontana wind (rare and
obsolete term); boron: very strong bora;
boraza: strong and annoying bora
(derogatory nickname); refolo: gust of
bora; this term is known to have been in use way back in 1481 when
Cristoforo von Thein describes Trieste as "the town where the
refolo blows"
