The hottest weather of the summer season occurred on July 5th through the 7th throughout the state of New Jersey. Many high temperatures on the 6th and 7th exceeded 100 degrees, some places even on the 5th exceeded 100 degrees. Because it was relatively dry, the afternoon temperatures and heat indices were the same during the afternoons of the 6th and 7th. For many areas, this was the first time since August of 2001 that high temperatures exceeded 100 degrees and also for two consecutive days. Trenton matched its consecutive day record (three) of 100 degrees or more originally set in 1966.
The hot weather started on the 4th and peaked on the 6th and 7th. An onshore flow lowered maximum temperatures on the 8th and 9th, even though some 90s still occurred. The heat wave ended for all on the 10th as a slow moving cold front moved through the state.
In response to the heat, cooling centers were opened in Middlesex and Morris Counties. In Gloucester County, the 146 residents of the West Deptford Manor Care Health Services were relocated after the air-conditioning failed. There were cases of heat exhaustion along Monmouth County boardwalks. The strain on electrical networks caused about 3,700 homes and businesses to lose power on the 6th. This included most of Milltown in Middlesex County where power was out for about 20 hours. The heat wave caused a water emergency declaration in East Brunswick. It was lifted on the 8th.
Highest temperatures included 105 degrees in New Brunswick (Middlesex County),  104 degrees in Trenton (Mercer County), Hillsborough (Somerset County), Marlboro (Monmouth County), Pennsauken (Camden County) and Lumberton (Burlington County), 103 degrees in Seabrook and Millville (Cumberland County), Somerville (Somerset County), and Flemington (Hunterdon County), 102 degrees at the Atlantic City International Airport, Boonton (Morris County), 101 degrees in Sussex (Sussex County) and Phillipsburg (Warren County), 100 degrees in Berkeley Township (Ocean County), 95 degrees in Cape May and 90 degrees in Barnegat (Ocean County).
