Tivano
Tivano is traditionally associated with the night and early morning and generally blows from the northern sector towards the south. It is linked to local thermal circulation between valleys, mountains and lake.
Breva
Breva tends to develop during the warmer part of the day, generally in the opposite direction. Daytime heating can make it particularly noticeable in the central and upper lake.
Why boaters care
A regular circulation may suit sailing and wind sports, but strong values or gusts require caution. Nearby thunderstorms and synoptic fronts can disrupt the normal Breva–Tivano cycle.
