I'm in Somewhatlazy's game as well.
The location is Zeland (Towers of Night, specifically), which from the maps has the same northern latitude as Belendale, but lies directly north of Orland and doesn't have an immediate mountain to create a rainshadow, assuming the winds blow from the west to the east.
So should our DM adjust the temp to be colder from the Zeland averages, or use coastal Far City's climate, with more extreme lows and highs due to the lack of a moderating coastal presence of the ocean?
