How was July for the record?

Compared to normal or climate average and contrasted with so many past July patterns of recent decades the lack of extreme heat stood out this year, and like the spring and start of summer so did the higher than normal cloud cover, rain odds and high humidity.

We ended up just over half a degree warmer than normal officially at Hartsfield, mainly due to warm nights rather than hot days. There were 16 days of 90 or above. The hottest was 94 on the 12th and the lowest 68 on the 23rd and 29th.

It’s worth pointing out that the “official” thermometer at the airport often runs around 2-3 degrees warmer than the rest of the area.

Like June no 95+ or 100+ degree days.

Official rainfall for the month was just over 8 inches or 2.8 inches above normal.

Most of the heat of significance was out west and Northeast:

Drought prevailed out west with dry weather central as well. Pockets of wet NE, SE and west-central and SW:

Notice despite what it may have felt like the July rain was far from extreme in Metro Atlanta with plenty of dry days even when not sunny. Plenty of areas rainfall ranged from 50-90% rather than above average as seen in the above two charts.

The nights were warm thanks to higher than average humidity, but daytime highs (max temp) averaged near-normal to a tad below normal:

Severe weather warnings were 7% above-normal for the month in our area:
