Weather
Called airport upon departure from ZZZ. Winds were said to be calm. Flight was direct to UT25. On final approach it was very bumpy and as I flared and touched down the wind changed from the right and picked up that wing. I lowered the right wing and aligned to the center line and touched down again. As I set down I was pushed left again and the left wheel hit a tumbleweed in the sand and right wheel touched down in the soft sand. I applied right rudder to get back on the runway and then the soft sand grabbed the wheel and pulled me hard left. At that point all I could do is keep straight as possible and brake to a stop in the sand and tumbleweeds.
Solo pilot reported encountering windshear during landing flare which caused the aircraft to departed the runway surface.
