Pressure and weather in Freeport

Freeport stands on the South Shore of Long Island in Nassau County, built along a network of tidal canals that drain into South Oyster Bay, with Jones Beach Island and the Atlantic Ocean immediately beyond the barrier. The elevation across much of the village is only a few feet above sea level, and the Nautical Mile waterfront sits right at the edge of the marsh. New York City is about twenty-five miles west. This is one of the most maritime settings in the metropolitan area, and it means local weather is governed almost entirely by the ocean. Nor'easters are the dominant influence on barometric pressure from November through early April: as a coastal low deepens south and east of Long Island, the barometer falls for a day or more, easterly gales pile ocean water through the inlets into the back bays, and tidal flooding follows even without heavy rain. Tropical systems and their remnants pose the same risk in late summer and autumn, with the 2012 storm surge remembered vividly here. Between systems, strong continental high pressure produces the crisp, dry days that follow a storm and a fast recovery in current barometric pressure. Summer is comparatively placid, with the sea breeze moderating heat and thunderstorms often weakening as they cross the cool water. Anyone using a barometric pressure forecast for Freeport should focus on the winter coastal storm season.

What this means for you

Can barometric pressure cause headaches? Life at sea level on Long Island's South Shore means the ocean drives the barometer directly, and coastal lows produce long, deep declines followed by hard-edged clearing. People here often say they feel a storm approaching a full day before the wind turns easterly. Check the barometric pressure forecast in Pressure Pal, treat it as your weather migraine log, and see pressure change today before the next coastal low arrives.
