During landing after a pattern flight and clearance for options; I approached final to land on Runway XXR; the airspeed; decent rate; power and flaps all set properly. Airspeed on final 55kt; full flaps deployed; Just before the flare; suddenly the airplane hit runway hard and bounced off. I attempted a go around but aircraft quickly stalled again and hit the ground hard again. The nose gear collapsed; prop struck pavement and came to stop. There were no personal injuries sustained. I informed the tower; I was ok and came out of the plane. I was able to move the plane off runway with the help of another person who showed up a few minutes later. I called the tower after securing the plane as advised.  I cannot think of any reason; other than a possible wind shear. However ATIS reported wind 310 @ 11knots without any mention of wind shear. If possible at all; improved monitoring for wind shear could be considered to prevent similar incidents in future.
C-150 pilot reported loss of aircraft control on landing resulting in a hard landing and causing the nose gear to collapse.
