April 5th in Sayreville tends to feel like a coin flip — expect something in the mid-to-upper 50s for a high, but the range over 57 years runs from a bitter 21° (1995) to a shirt-sleeve 77° (2010). Nearly half the time, you're looking at some form of precipitation, though snow is essentially off the table at this point in the season.
Sayreville knows extremes. The thermometer has swung from a brutal -13° in January 1984 all the way up to 105° during a July 2010 heat event — a 118-degree spread that captures just how punishing a mid-Atlantic continental climate can be. The wettest single day on record, 7.96" on August 28, 2011, was courtesy of Hurricane Irene.
Summer is the main event here, with highs peaking around 88° in mid-to-late July and the wettest stretch of the year landing right on its heels in late July. Winters are cold but not brutal — January highs average just 39° — making the shoulder seasons of May and September the sweet spot for comfortable weather.
