It's been many years since I was in Newcastle but, isn't there a rather steep increase in the land elevation just in from the coast?
This being the case, you have lessened the available volume for the airflow, increased the pressure, and you now have a squirt effect, like your finger on the end of a garden hose... added to this there would be thermal increases as the cooler air from the sea warmed over the land, warm air rises and it's already travelling, so a vectoral addition would result in more windspeed up the slope.

It could also just be that the weather station is at a higher altitude and hence in a higher airstream.

It could aslo be that I shouldn't have taken so many drugs in my youth and hence waste my time thinking about these kinda things now...

Oh Gawd, where's the wind?
