April 4th in Endicott sits in that unpredictable shoulder season — the average high is just 48° but there's a 32% chance of snow still lingering. The date's range tells the whole story: 73° in 1981 versus an 11° low back in 1954.
Endicott's weather has real teeth on both ends. The thermometer has swung from a brutal -20° in January 1957 all the way to 98° in July 1988, and a single day in September 2011 dumped 7.49 inches of rain — a reminder that the Southern Tier can get walloped when remnant tropical systems push through.
Summer is the sweet spot, with average highs peaking around 79-80° in mid-July before the long slide toward winter's 27° highs in late January. If you're avoiding the wet, steer clear of mid-June, the area's rainiest stretch at over an inch per week. Spring and fall offer mild temps but keep an umbrella handy — precipitation is a near-constant companion.
