Today’s light rain is tied to a weak coastal low situated a few hundred miles offshore. Most New Jersey locations will see only nuisance rainfall, with totals unlikely to exceed a quarter-to-half inch, mainly affecting the I-95/NJTP corridor. Coastal winds are gusting over 30 mph, primarily from the northeast, enhancing surf conditions to around 7 feet with hazardous rip currents. Beachgoers are advised to stay out of the water while marine conditions settle by late Thursday morning.
The combination of low humidity and moderate temperatures over Thursday through Saturday promises ideal outdoor conditions, with Thursday reaching slightly above 80°F in a “dry heat” scenario. Nights remain cool and refreshing, perfect for evening walks, dining al fresco, or enjoying New Jersey’s parks and waterfronts. By Sunday, an upper-level disturbance from the north may bring more substantial rainfall, setting up cooler-than-average temperatures to start the following week.
This week showcases the balance between lingering summer warmth and the crisp comfort of early fall, providing ideal conditions for outdoor activities, weekend adventures, and enjoying New Jersey’s scenic landscapes before the cooler season sets in.
