FREEHOLD, N.J. — A dangerous combination of extreme heat and worsening air quality is blanketing parts of New Jersey through midweek, as the National Weather Service and state environmental officials issue multiple warnings.
An Extreme Heat Warning remains in effect through 8 p.m. Wednesday for western Monmouth, Ocean, and southeastern Burlington counties, where heat index values could reach up to 107 degrees. The warning, issued by the National Weather Service in Mount Holly, notes that high humidity and overnight lows near 80 degrees will offer little relief.
“The hottest temperatures and heat indices will occur Monday and Tuesday,” the advisory stated, warning of significantly increased risks of heat-related illnesses. Residents are advised to stay hydrated and avoid prolonged outdoor exposure.
Alongside the heat, a Code Orange Air Quality Alert was issued by the New Jersey Department of Environmental Protection for Monday in Ocean and southeastern Burlington counties. The alert indicates that ozone levels may be unhealthy for sensitive groups, including children, seniors, and individuals with respiratory or heart conditions.
Meteorologists forecast a high near 95 degrees on Monday, with a heat index around 106. Overnight lows will hover near 78. Tuesday is expected to be the hottest day, with temperatures peaking near 100 and a heat index of 104.
Cooling possible later in the week
Conditions may begin to ease Wednesday afternoon, though temperatures will still approach 96 degrees. Scattered showers and thunderstorms are possible by late Wednesday and continue through Friday, which could bring some relief.
Overnight temperatures will gradually dip as the week progresses, with lows in the mid-70s Wednesday night falling to the mid-60s by Thursday night. Daytime highs will drop into the 80s Thursday and 70s by Friday.
“Low temperatures near 75 to 80 degrees and high humidity will not offer much relief from the heat at night,” the National Weather Service noted.
The extreme heat and ozone alert follow a stretch of hot weather across the Northeast, marking one of the first prolonged heat events of the summer in New Jersey.
High heat and stagnant air will continue to challenge vulnerable populations and emergency responders across the state.
