Influence of the weather on the boat trips
The most sensitive are boat trips type fish picnic. In the case of the strong wind of the south (Jugo) and especially, the southwest (Garbin)
is not recommended going on this trip. In Novigrad, the harbor is not very sheltered, so large waves can be seen even before the departure.
Interestingly, any Northeast wind, even strong (and despite the name: Bura) makes here a quiet sea and favorable conditions for navigation.
If the weather forecast is not ideal, you can try a bus trip.
