What does bora mean?
The bora is a fierce, cold, dry wind that blows from the north-east across the mountains onto the eastern shore of the Adriatic Sea, most famously affecting Trieste and the Dalmatian coast. Formed when dense cold air spills over high plateaus — such as the Karst behind Trieste — it descends rapidly, producing sudden, violent gusts that can exceed a hundred kilometres per hour and pose serious hazards to shipping, aviation, and coastal life. Meteorologists distinguish a lighter, more continuous 'white bora' under clear skies from a darker, stormier version accompanied by cloud. The name derives ultimately from Boreas, the ancient Greek personification of the north wind, via Latin and Italian. Similar cold downslope winds occur elsewhere, including on Russia's Black Sea coast. Though chiefly a regional and meteorological term, the bora has entered broader English through travel writing, weather reporting, and literature about the Mediterranean, standing as shorthand for a wind of notorious strength and unpredictability.
nounA cold, dry north-easterly wind that blows down from the mountains to the eastern coast of the Adriatic Sea, especially around Trieste and the Dalmatian coast.
- A violent, cold, dry north-easterly katabatic wind descending from the mountains onto the northeastern Adriatic coast, notably near Trieste and Dalmatia.
- By extension, similar cold downslope winds in other regions, such as those of the Black Sea coast (Novorossiysk).
"The bora swept down from the Karst plateau, whipping the Adriatic into whitecaps and grounding the ferries."
"Fishermen in Trieste know to moor their boats double before the bora arrives, since its gusts can strike without warning at well over a hundred kilometres an hour."
"The old town's stone arcades were built partly as shelter from the winter bora that funnels down through the mountain passes."
The anglicized plural 'boras' is standard in English; the Italian-style plural 'bore' occasionally appears in specialist writing but is rare.
"Several destructive boras battered the harbor that winter."
The bora is so violently gusty that Trieste's port once had to be redesigned around it — sailors have long blamed this one wind for capsizing ships that seemed perfectly seaworthy.

Etymology of bora
The word bora comes from Italian (and Venetian dialect), where it denotes the same Adriatic wind. Italian took it from Latin 'boreas', itself borrowed from Greek 'Boreas', the god and personification of the north wind. English adopted the term in the nineteenth century, primarily through descriptions of Mediterranean weather and geography. Its cognates include 'boreal' and 'hyperborean', both built on the same Greek root for 'north'.
How bora is actually used
A technical term in meteorology and regional usage rather than everyday English; familiar mainly to readers of weather reports or literature about the Adriatic. It is always used attributively as 'the bora' or 'a bora'. The word carries connotations of harshness and sudden violence.
