A scorching summer ahead for New Jersey: temperatures well above average
New Jersey is bracing for one of its hottest summers on record, according to the latest weather forecasts. After a hot start to June, with temperatures already reaching the low 80s°F (around 27°C) across the Garden State, long-range outlooks suggest that conditions will only intensify, with extreme heat becoming the dominant theme of the season.
Cooler June, but July and August will sizzle
The Old Farmer’s Almanac projects that while June might trend slightly cooler than average, the relief will be short-lived. Starting in early July, temperatures are expected to surge, running about 3°F (1.7°C) above average. In August, that difference may climb to 4°F (2.2°C) above normal.
In 2024, New Jersey experienced its third-hottest summer in over a century, even though temperatures were only 2°F (1.1°C) above normal. This highlights how even modest increases can result in significant heatwaves and record-setting seasons.
A look back: New Jersey’s hottest summer on record
The hottest summer ever recorded in New Jersey happened in 2010, when the average temperature reached 75.7°F (24.3°C) — that’s 2.6°F (1.4°C) above the state’s long-term summer average of 73.1°F (22.8°C). This year’s forecasts suggest that 2025 could challenge or even break that record, if current trends hold.
Forecast pattern: widespread, persistent heat
The projected pattern indicates a long stretch of intense heat, particularly across urban centers like Newark, Trenton, and Asbury Park, where the urban heat island effect could make conditions even more oppressive.
A persistent high-pressure system, combined with low wind activity and high humidity, could push real-feel temperatures toward 100°F (38°C) during the peak of summer, creating dangerous and uncomfortable conditions statewide.
