The south is sub tropical, the area around marwood will thus feel very hot, the woods will keep the air very mousty. coastal areas and hill stations will be lovely in the south, nice, windy and cool.
Keep in mind that mountains block air streams and thus (rain) clouds.
Also, the inner sea is probably more warm then the outer sea, and if there is a circular stream of hot and cold waters in it, one side of the continent could be warmer than the other.
Waves are also bigger in the ocean instead of the inner seas and straights connecting the outer with the inner sea, could be quite rough and possible dangerous.
In Madina we also roleplay a monsoon period during the winter coming from somewhere east, passing slowly over the isle, turning it into one big muddy !@#$ hole.
