On average the water temp at the pier probably varies just a few degrees from the buoy readings.
Maybe a little higher (at the pier) during 'extended warm periods' (like we are currently in) and probably a little lower after it's been cold and cloudy for a few days.
The relatively shallow water around the pier is much more 'weather sensitive' than it is 12 miles offshore in 86 feet deep water.
BTW, I've recently been doing some extensive research and exhaustive statistical analysis of the historic data from that buoy (42012) and found it interesting.
The amount of water temperature variation that can be experienced during the winter & spring months is about twice the dispersion of water temps experienced in the summer and fall.
See the numbers labeled STDev (Standard Deviation).

In part that's why I try to warn folks not to get too excited when the water temp rises a few degrees in mid winter.
It's very likely going to go back down that much (or more).
There is a LOT of room (statistically) for the water temp to move up and down this time of year...
Oh yeah, this most recent February and January (2015) were 'slightly above the mean average for those months.
It sure would be great if we had reliable water temp data reported from the pier!
