April 4th in Corning sits squarely in transition season — expect a high around 50° and a low near 28°, with just over a 50/50 shot at precipitation. The date has swung wildly in the past, from a balmy 80° in 2010 to a brutal 17° low in 1995, so don't put the layers away just yet.
Corning's weather has real range — 120 degrees of separation between its all-time high of 100° (August 2001) and its record low of -20° (January 2011). The wettest single day on record dumped 5.83 inches back in August 1937, and the Blizzard of '93 buried the city under nearly 25 inches in a single March day.
Summer is Corning's sweet spot, with highs peaking around 81°–82° in mid-to-late July and the best stretch of dry, warm weather before things get soggy the last week of July. Winter bites hard — January highs average just 31° — so plan cold-weather visits with layers and low expectations. Spring and fall offer pleasant shoulder seasons, with April and October both averaging highs in the upper 50s.
