Weather in Neverwinter

The City is temperate, shielded by sea breezes from the worst of winter storms and summer heat. The Neverwinter River flows warmly throughout the year, steaming on chilly winter days and keeping the port free of ice in the coldest months.

Neverwinter Campaign Setting

Knowing the weather have always helped me to narrate the scene. Looking for information about the weather in Neverwinter has been pretty limited. There are some generic texts in some campaign material but nothing really tangible. So after some research I came to the conclusion that Bergen in Norway would fit Neverwinter.

This is a very simple way of generating the weather and I find that I don’t need any more details. I usually keep especially turbulent or fantastic weather as plot pieces or random encounters.
