Human Factors; Weather
Well prior to top of descent into EWR we reviewed performance and FM wind shear precautions; profiles; procedures as EWR was landing runway 29 due to high winds and LLWS advisories. We assessed and chose flaps 3 approach and incorporated into brief to include the defined touchdown zone/go around point and verbal review of procedure.First Officer flew a good approach in very gusty conditions but wind shift and gust at approximately 40 feet in transition towards flare caused auto thrust to over correct resulting in a balloon/float. I directed a Go Around (GA) as we approached the end of our pre briefed touchdown zone.While directing the GA and monitoring power/position; I reverted to non-standard phraseology (from military career) with the tower '... on the Go' versus '... Going Around'. In the subsequent high work load of tower vectors; 2 different altitude assignments and a switch to approach frequency; I failed to recognize and correct the flaps to position 2 from the flaps 3 approach position. We evidently reverted to and called the normal(full flap) go around profile call outs and checked 'flaps 3' which resulted in a 5-10 knot flap over speed during the go around.Neither tower nor approach asked the reason for the GA and it was; frankly; too busy a time to give one.  Rebriefed subsequent approach with a selected speed and manual throttles to mitigate engine spool ups/downs; and though a challenging approach; landed uneventfully.
Extremely gusty winds prompted a crew to elect to do a go-around just prior to touchdown. The second approach was uneventful.
