New Jersey’s First Frost Forecast for 2025, Here’s What to Know

July brought sizzling heat to the Garden State, with plenty of days that felt perfect for lounging by the pool.

Now, as we step into August, the question is, will the warmth continue? Traditionally, August is New Jersey’s hottest month, but so far, the first few days have been pleasantly mild.

Of course, there’s still plenty of summer left for those steamy afternoons we expect this time of year.

Back-to-school shopping is already underway, a clear sign that the seasons are beginning to shift.

The buzz of preparing for a new school year fills stores, even as many of us are still squeezing in those last summer barbecues, beach days, and poolside afternoons.

Personally, I’ve been in the water nearly every day this summer but lately, that water has had a surprising chill. I’m hoping for a few more scorchers before autumn arrives.
