April 5th in Glassboro tends to land squarely in that unpredictable stretch of spring — expect a high around 59° and a low near 40°. But the date's 85-year track record shows real range: it's hit 81° as recently as 1942 and dropped to a sharp 26° back in 1965. There's about a 1-in-3 chance of rain, though snow is nearly off the table at just 1%.
Glassboro's weather has some serious teeth — the all-time high of 104° on July 3, 1966 is brutal, and the -7° low on January 17, 1982 is no joke for South Jersey. The wettest single day on record dumped 8.02 inches on July 28, 2013, while the Blizzard of '96 buried the area under 27.6 inches on January 7th of that year.
Glassboro peaks in the third week of July, when average highs reach 88° — classic humid Mid-Atlantic summer. If you're cold-averse, avoid mid-January, when highs average just 39°. July is also the wettest stretch of the year, so summer visitors should keep an umbrella handy.
