PA-18 cub pilot reported experiencing a ground loop during landing in gusty wind conditions.

Narrative:

The sortie was planned as a continuation training event for the solo pilot. Following seven landing patterns of varying flap settings and type; the 8th approach and landing was to a wheeled touch down with the flaps retracted; full stop. Winds according to the visible wind socks on the airfield indicated a right quartering headwind of approximately 5 knots; which differed from the information provided by the ASOS that was checked on each pattern to compare with the wind socks. Also noted was that turbulence and wind changes were gradually descending from 7;200 MSL to approximately 6;500 MSL during the patterns and the intent was to full stop on the eighth landing to avoid dealing with gusty winds.during a planned full stop landing at approximately 30 mph in a 3-point aircraft attitude following an uneventful right to left wheeled touchdown for the right crosswind; the aircraft was exposed to a strong wind gust from the left side resulting in a the aircraft rotating on three wheels to the left off the runway despite full right rudder and some right brake. The aircraft nosed down during the loop and the prop struck the ground along with the right-wing tip; right aileron; and right elevator. There were no known injuries to the pilot who was the sole occupant. The pilot egressed the aircraft and together with ground crews righted the aircraft and moved it to the aircraft hangar.
