This is the warmest September on record for Denver.

Sunday's 90-degree heat sealed the deal.

"Cooler temperatures that will move in Monday and Tuesday aren’t cool enough to change that," said Storm Station 7 Meteorologist Matt Makens.

The average monthly temperature this year is about 69.7 degrees, according to the National Weather Service in Boulder. The previous record was 68.3 degrees - set in 1948.

This September is currently the fourth driest on record, Makens said.
