NJ Heat Wave Incoming: Temps Soar Toward 90° This Week

New Jersey is about to skip spring and jump straight into summer as an unusually strong April heat wave builds across the region. The upcoming 7‑day forecast tells a dramatic story: temperatures will surge into the low 80s Monday, mid‑80s Tuesday, and could touch 90° by Wednesday across inland areas — a level of heat more typical of late June than mid‑April.

Shore communities will run cooler, but even there, temperatures will climb well above seasonal averages, with several days in the 70s and even a mid‑70s spike Thursday.

This warm spell arrives after an extended dry stretch, and while there is a small chance for a shower Monday afternoon or evening, forecasters note that most of the moisture will likely fizzle out before reaching the state. The heat, however, will not — it stays locked in through the end of the week before a modest cooldown arrives next weekend.

🌡️ What’s Driving the Heat?

A strong ridge of high pressure is building over the East Coast, allowing warm, dry air to surge northward. This pattern is classic for early‑season heat waves and often leads to:

• Sunny or partly sunny skies
• Low humidity early in the week
• Rapid inland warming
• Cooler but pleasant coastal conditions

By midweek, the ridge strengthens further, pushing temperatures toward record‑challenging levels on Wednesday.
