April 4th in Bridgewater runs mild but moody — historically, highs land around 59° with a coin-flip chance of rain. The date has seen a 52-degree swing across its 62 years of records, from a bitter 25° low in 2013 to this year's warm 77° high.
Bridgewater earns its four-season reputation the hard way: 102° scorchers in July, -3° in February, and a single day in September 1999 that dumped over nine inches of rain. The extremes here aren't rare anomalies — they're just part of living in central Jersey.
Summer is the main event, with highs peaking around 86-87° in mid-July and the wettest stretch arriving right on its heels in late July. Winters are genuinely cold — January and February average highs in the upper 30s to low 40s — so late May through early October is the sweet spot for comfortable visits.
