Pressure and weather in North Port
North Port sits barely above sea level on flat pine flatwoods and former wetland between the Myakka River and the head of Charlotte Harbor, about ten miles from the open Gulf. The pressure year is dominated by one thing. Hurricane season runs from June through November and peaks in September, and this stretch of the southwest Florida coast has taken repeated direct hits, with Charlotte Harbor acting as a funnel that concentrates storm surge as a system comes ashore. A landfalling hurricane produces the fastest and deepest barometric fall this location will ever record, tens of hPa within hours, and the eye passage gives the sharpest possible minimum followed by an equally abrupt rise. Outside of tropical systems, the summer here is governed by sea-breeze convergence rather than by travelling weather systems. The Gulf breeze pushes inland from the west while the Atlantic breeze pushes in from the east, and where the two collide over the peninsula, usually in the afternoon, thunderstorms fire almost daily. These produce small, brief, local pressure perturbations rather than the broad falls of a frontal system. Winter is the dry, settled season, when the occasional cold front reaches this far south, often weakening and stalling over the peninsula.
What this means for you
Tropical systems here produce pressure changes larger and faster than anything most locations ever see. A barometric pressure forecast watched from the first advisories gives days of warning before the fall begins.
