Is there areas in the old town that are more sheltered from the wind; other than being inside?
Depends entirely on the local buildings and directions of streets.
The wind is generally from the North, so a N-S running street north side of Chora hill will probably be windy. The south side of Chora hill generally not so windy.
from your artist / drawing point of view I think the lanes of the old town will be fairly sheltered from wind as they have twists and turns all over the place and the outside building structures shelter any wind
Thank you both for your helpful responses.
Most of the wind seem to blow down the bay toward the airport runway. Down at that point you see windsurfing clubs and the sand dunes down there tell all. If you see my trip report I cover the area and point out things like that. Also photographing in the lanes I am always looking for that perfect shot of say a lady sweeping with her broom with the old buildings as a background. I guess you will be looking for similar things.
