Is it worst directly at the front of the eye, the right edge of the eye where the winds are perpendicular to the coast, or somewhere else?
Since coastal terrain can make a diff, assume it is all the same for sake of this question. Thanks.

If you are right inthr midle of the landfalling eye, you get the extreme winds from one direction for a while, then the cslm of the eye, which can last an hour or more in a large eye moving slowly, then the winds resome from the opposite direction. this change in directions can be the end for structures that have already been severly dsmaged on the windward side froim the first sode of the eye.
If you are right in the edge of the eye, then you get the extreme winds for a very long time, relative to those who have experienced the passage of the wall, and are now in the eye. But, you will not experience the radical change in direction that those in the middle do.
In Andrew, the northern eye wall just "trained" over an area. Many structures were completely wrecked on the east side, and completly undamaged on the west. My home had a beach ball on the screen patio on the West side of the house, and it never moved. Unfortunately, most of my possesions that I cared about were in an east side bedroom on the second floor. Needless to sat, I lost everything. The struxcture was condemned.
Hope this helps.

oops
soory....I just read your thread, and understood that you were asking about surge.
The Eastern eye wall would push more water by wind, but the eye also, due to the extremely low pressure, allows a dome of water to rise up, since there is so much less air pressing down on the surface of the ocean.
The worst surge is a combination of these effects.
Locally, the height of surge varies due to the depth and shape of the ocean bottom. Shallw waters do not allow waves to extend down the whole way (half the height of a wave is under water) to the bottom. The energy of the wave is tranferred into increasing wave height, thuse builing up more surge. The water literally has no place to go but up.
