April 4th in Manville typically feels like a cautious step into spring — expect a high near 58° and a low around 39°, with a coin-flip chance of rain. The date has swung wildly over the years, from a balmy 79° in 1981 to a bitter 26° low in 1995. No snow in the forecast, though — that chapter is essentially closed for the season.
Manville's weather has real teeth at both ends: the thermometer has soared to 105° (July 7, 2010) and plunged to -13° (January 22, 1984), a 118-degree spread that says a lot about New Jersey's continental character. The wettest single day on record dumped 7.96 inches on August 28, 2011 — remnants of Hurricane Irene — while a February 2006 snowstorm buried the town under 19.8 inches in a single shot.
Summer is the main event in Manville, with highs peaking around 88° in late July and the wettest stretch of the year arriving right on its heels. If you're avoiding heat, aim for October through November, when highs ease back into the 50s and 60s. Winter runs cold but short — the coolest week of the year averages just 38°, and by April the rebound is well underway.
