Figuring out the best time to visit Northern New Jersey is usually dependent on what you plan to do during your trip. Summertime is filled with outdoor activities (hiking in High Point State Park, fishing at Greenwood Lake) and high temperatures, whereas the fall and spring seasons offer milder weather. Winter can produce cold weather — after all, you’re not far from New England — so your best bet is to make a visit in the other three seasons. During the summer, locals flock to the Jersey Shore for some much needed sun and sand, but expect large crowds if you go. Fall and spring afford pleasant temperatures that make exploring the area easier and more enjoyable.
