I was asked why it has been “such a hotter summer than normal for much of the country”. Rather than go into a lot of details I will let the graphics do the talking. These are directly from the CDAS (Climate Data Assimilation System) from NOAA
30-day average temperature anomalies. Blues and greens indicate below normal, and reds and yellow indicate above average. The chart on the bottom corresponds to the colors showing the number of degrees below or above average.
45-day temperature anomalies
60-day temperature anomalies
I think some people forget that Summer usually is hot! , That being said a good portion of the US has had below “average” temperatures this Summer.
