Bora or nevera? Two Adriatic hazards every visiting skipper should understand
Ask a sailor preparing for a first cruise in the northern Adriatic which local weather hazard they have heard about, and the answer will almost certainly be the Bora.
Before long, they will learn where it blows hardest, which channels become dangerous, which anchorages should be avoided, and where to find reliable forecasts. Every marina, pilot book and cruising guide discusses the Bora. It is rightly respected as one of the defining winds of the Adriatic.
My own experience was no different.
Having sailed extensively in Norway and the French Mediterranean, I was already familiar with powerful katabatic winds. Before arriving in Croatia, I had read about the Bora, learned how it develops, and understood how to monitor forecasts
What I had never heard about was the Nevera.
I first encountered the word in a newspaper article describing the violent storm that struck Rovinj in June 2025. Later that same year, I experienced three Neveras myself. One of them dragged my boat ashore while we were anchored overnight in the Venetian Lagoon, despite what appeared to be a relatively benign weather forecast.
That experience made me realise something important. I had learned how to forecast the wind but I had never learned how to forecast convective weather. And that, I believe, is a gap shared by many sailors visiting the Adriatic.
