Pressure and weather in Port Charlotte
Port Charlotte spreads across low ground, mostly under twenty feet, on the north side of Charlotte Harbor where the Peace and Myakka Rivers empty into a wide shallow estuary open to the Gulf. Being on the Gulf side of the peninsula sets the summer rhythm: the west coast sea breeze pushes inland from late morning, meets the east coast breeze somewhere over the interior in the afternoon, and the storms that fire on that collision often drift back toward the coast in the evening. Southwest Florida records among the highest lightning densities in the United States as a result. The barometer barely registers any of it, showing mainly the regular semidiurnal tide that is a distinct feature of tropical latitudes. What it does register is the hurricane season, and this particular stretch of coast has been struck more directly than most, with Charley in 2004 coming ashore here as a compact violent category four and Ian in 2022 pushing a catastrophic surge up the harbour. The shape of Charlotte Harbor funnels and amplifies surge, so for systems approaching from the southwest the water hazard runs well ahead of the wind. Winter brings a handful of cold fronts down the peninsula, each a brisk wind shift and a short dry spell, and very little else.
