Much like this past July, August was a hotter and drier month than normal. Despite a June with rather close-to-normal numbers, the two most recent months brought the summer temperature and precipitation to top-10 levels for hot and dry conditions. More on summer ’22 later in this report, but first to discuss is a record hot and quite dry August.
The August average temperature of 77.4° was 3.8° above the 1991–2020 normal, ranking as the hottest on record. Eight of the ten warmest Augusts since 1895 have occurred since 2001. The average maximum of 88.5° was 4.7° above normal, the hottest on record, while the average minimum of 66.2° was 2.9° above normal, tied for 5th warmest. North Jersey averaged 75.7° (+3.8°, warmest on record), the south 78.4° (+3.8°, warmest on record), and the coast 77.9° (+3.2°, 3rd warmest).
Statewide, August precipitation averaged 2.61”, which is 1.96” below normal, ranking as the 22nd driest. The north came in at 2.31” (-2.25”, 18th driest), south 2.82” (-1.75”, 29th driest), and coast 2.54” (-2.06”, 25th driest). As the map shows, virtually the entire state had a monthly total below the statewide 4.57” normal. Exceptions were found in isolated west central and central coastal areas where several storms quickly deposited hefty totals. Less than half the normal monthly rainfall fell in a good portion of the north and in scattered areas of the south and north coast.
