Pressure and weather in Cancun
Cancún stretches along a narrow barrier island and the mainland behind the Nichupté lagoon on the northeastern corner of the Yucatán Peninsula, where the Caribbean meets the Gulf of Mexico. It is a tropical place, and tropical pressure behaves differently from mid-latitude pressure. For most of the year, the biggest regular change on the barometer is the atmospheric tide, a twice-daily rise and fall of two to three hectopascals that peaks around ten in the morning and ten at night. Weather systems are the exception rather than the rule. The steady easterly trade winds keep the air warm and humid, and the wet season from about May to October brings frequent showers and thunderstorms. Hurricane season overlaps it, and the peak from August to October is when a storm can bring the deepest pressure falls imaginable. Hurricane Gilbert in 1988 and Hurricane Wilma in 2005, one of the most intense Atlantic storms on record, both devastated the area. In winter, a different visitor arrives. Cold fronts from North America, called nortes locally, push down across the Gulf and reach the Yucatán, bringing a gusty north wind, cooler air and a quick pressure rise.
What this means for you
Cancún's barometer is steady for long stretches, which makes both the winter nortes and any tropical system stand out. During hurricane season a barometric pressure forecast is especially worth following, and a migraine tracker app can help you tell whether the rare large drops or the everyday heat and humidity play a bigger role in your weather migraine days.
