Fall officially begins tonight at 8:05 p.m. ET. The Fall Equinox marks the start of astronomical fall in the Northern Hemisphere. Around this time of year, daylight and nighttime are nearly equal. From here, the days keep getting shorter until the Winter Solstice on December 21, with cooler temperatures and changing leaves following close behind. Fall also brings its own hazards to New York City. Atlantic hurricane season continues through November 30. Nor’easters become more common as the season progresses. Fallen leaves can clog catch basins and worsen street flooding during heavy rain. Daylight saving time ends Sunday, November 1, bringing earlier sunsets, and New York City’s heat season begins October 1. During heat season, building owners must keep apartments at 68 degrees or warmer from 6 a.m. to 10 p.m. whenever it's below 55 degrees outside, and at 62 degrees or warmer overnight from 10 p.m. to 6 a.m., no matter the outdoor temperature. @nycemergencymgt monitors conditions around the clock with the National Weather Service and City agencies.
