Wheatley Hills were not at their best as they crashed to a 17-12 defeat at Pocklington.
Bizarrely, both teams seemed to do better playing against the wind with Pocklington bossing the first half and Wheatley scoring their points in the second.
Two tries from the home side saw them lead 11-0 at the break.
Despite having the wind behind them, Wheatley struggled to get out of their own half and never offered a threat to the Pocklington backline.
Playing into the wind, Wheatley were much improved but failed to take advantage of some good territory.
Martin Ballshaw was their only try-scorer although they were also awarded a penalty try which Matt Green converted.
Hills lie sixth in North One East.
Wath on Dearne slipped off the pace in Yorkshire One when they were beaten 32-8 at Heath.
After an early Heath try, Wath equalised when a good backs move saw winger Brad Taylor race over.
Full back Sam Jones slotted over a penalty goal to give Wath an 8-5 half time lead, but Heath took full advantage of the wind in the second half to run in four more ries.
Thornensians were unlucky to lose 17-15 at home to Old Modernians in Yorkshire Three.
Modernians scored first with a dubious try which was converted.
Thorne reduced the arrears when second row Andy Evans touched down but Konrad Hanson was unable to land the conversion in the difficult, windy conditions.
The visitors edged further in front with a penalty and then, on 30 minutes, scored their second converted try to lead 17-5 before Thorne pulled back a 37th minute try by full-back Zak Holgate.
Hanson was again unable to convert, but Thorne were now within seven points of their opponents and in with a chance of a losing bonus point.
They made certain of the bonus ten minutes into the second half when winger Brett Hunt raced over for a third try.
