Pressure and weather in Saint James
Saint James sits on the north shore of Long Island in the Town of Smithtown, Suffolk County, close to Stony Brook and the bluffs above Long Island Sound. Water on nearly every side gives it a maritime-moderated climate and a distinctly coastal barometric pressure pattern. Nor’easters are the dominant feature: lows forming off the mid-Atlantic and deepening as they move northeast pass close enough to Long Island to produce the steepest and most sustained falls in current barometric pressure the area records, often combined with strong onshore wind and coastal flooding. Because these systems can intensify rapidly just offshore, the rate of change is frequently more pronounced here than the seasonal averages suggest. Winter also brings arctic air masses behind departing storms that push the barometer up sharply, and the Sound keeps the north shore a few degrees milder than inland Suffolk through the cold months. Late summer and early autumn carry the tropical risk, when systems moving up the eastern seaboard hold weather pressure down for a day or more. Summer between events is comparatively settled, with the sea breeze the main daily influence and short dips in air pressure today from passing thunderstorms. For anyone here who reacts to barometric pressure headaches, a barometric pressure forecast is most valuable from October through March.
What this means for you
Can barometric pressure cause headaches? On Long Island’s north shore rapid offshore deepening is the clearest test, because a coastal low can strengthen quickly and move the barometer a long way in under a day. Using this barometric pressure forecast with a migraine tracker app like Pressure Pal lets you see pressure change today as it accelerates. Track barometric pressure today and get alerts when atmospheric pressure starts to fall.
