The heat is on, and some games are off.

But before any reschedulings, the Nashua High School South boys and girls soccer teams took care of business with wins over local rival Alvirne.

But the early September heat, with temperatures expected to be in the 90s the next couple of days, has impacted the local schedule. Tuesday’s Nashua North boys soccer game at Concord was postponed to Oct. 14, while the girls game at Stellos Stadium was moved to Oct. 16.

Also today’s Bishop Guertin vs. Nashua South girls soccer game that was set for 4 p.m. at Stellos Stadium was postponed to Sept. 30. The nightcap 6 p.m. boys version of the rivalry was still on as of this posting.

Meanwhile, here’s what we know from what was played on Tuesday:
