July 2018 weather recap: After a hot start, month cools down, gets wet

Monday, August 6th, 2018 7:40am MDT

The month of July was somewhat a tale of two months in one.  The first half was most notable for their unseasonably warm temperatures and relatively dry conditions.  The second half saw a few days of heat but for the most part was considerably cooler and wetter.

Thornton saw an average temperature for the month of 73.5 degrees.  Out at Denver International Airport where the Mile High City’s official readings are taken, the month saw an average of 75.3 degrees.  Long term, the month of July sees an average of 74.2 degrees in Denver so while Thornton was cooler than that, Denver was warmer.

Thornton had its highest temperature reading of 99.9 degrees on the 19th and its coldest of 47.7 degrees on the 1st.  Denver saw its warmest reading of 99 degrees on the 3rd and its coldest of 47 degrees on the 1st.

In terms of precipitation, Denver’s long term July average is 2.16 inches.  Thornton easily bested that number with 3.66 inches in our rain bucket.  The Mile High City fell well short with only 1.03 inches.
