Wind and land are a crazy mix. Think of it this way;
The lee shore of a small island can be like putting your finger over a garden hose. There will be shelter from the wind on a somewhat breezy day (low water flow and you can stop it with your finger). If the wind starts piping up and it will get a little gusty (turn up the flow and it starts to leak). If it really starts to blow it can feel windier on the lee shore than on the windward shore. This is not an explanation to read all weather, just trying to prove that conditions can change quite a bit in a short distance. You get the idea....
Now throw in temperature, hills, valleys, mouths of rivers, currents, wind direction... Local knowledge and experience is the only way to learn.
