The nearby Adriatic Sea brings warm, humid air currents during many days throughout the year, which encourages the formation of the rainfall that is a characteristic of this area, amounting to some 1350mm annually. These so-called Scirocco winds tend to confer a Mediterranean climate, which counterbalances the predominating continental tendency. Another wind, the Bora, blowing in from the east, is the dominant influence over the Isonzo, with strong, cool, dry currents. Its influence is felt particularly in August through October, when it contributes to preserving aromatic compounds in the white-wine grapes.
