First Day of Summer – Daylight
As during Summer Solstice, the sun is in it's most northern portion of it's orbit in the sky, the farther north you go, the longer the days.
The Town of Massena, has the longest day in all of New York at 15 hours, 36 minutes, and 52 seconds of daylight as it's center point is closest to 45 degrees parallel of any town, because part of the Robert Moses State Park (Barnhart Island) extends north of the 45 parallel.
Staten Island has the shortest first day of summer at only 15 hours, 4 minutes, and 45 seconds. Then again, the first day of winter has the longest daylight in all of New York State in Staten Island.
That said, if you are looking for a late sunset in Massena, you'll be disappointed. Massena's 8:49 PM sunset doesn't hold a candle to Porter's sunset at 8:59 PM in the western portion of state.
