Today's barometric pressure in Corpus Christi, a 48-hour pressure chart, and a risk score for weather-triggered migraine and headache, based on pressure drops, humidity, and temperature changes.
Loading live forecast for Corpus Christi...
Corpus Christi's Gulf Coast barrier island geography means constant maritime influence. Sea breeze fronts create daily pressure cycles, and the city's exposure to tropical systems from June through November brings the most intense barometric events.
Worst season for migraines: January through March. Corpus Christi's Gulf Coast position means a hurricane can bring a severe single drop, but those are rare. Most pressure drops come with winter fronts from January through March, peaking in January, when 46% of days see a 5 hPa drop. Summer brings daily sea-breeze thunderstorms around the Laguna Madre and Corpus Christi Bay but almost no pressure movement, 3% of days or fewer in each summer month.
Common triggers in Corpus Christi: Gulf hurricane and tropical storm pressure crashes, persistent Gulf humidity and sea-spray moisture, rapid cold front passages during blue norther events. Corpus Christi sits on a bluff overlooking Corpus Christi Bay, sheltered by Mustang and Padre barrier islands. The city is surrounded by water on three sides, including the hypersaline Laguna Madre to the south, the bay to the east, and the Nueces River to the north. This water-dominated geography ensures constant high humidity and amplifies the pressure effects of approaching tropical systems. The Coastal Bend's geographic projection into the Gulf intercepts tropical systems that might pass north or south of other Texas cities.
Typical pressure: Corpus Christi averages 1016 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 985 hPa. Swings of 4-10 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Corpus Christi ranks #76 of 100 in our 2026 U.S. Migraine Risk Index, where #1 is the most challenging city for weather-driven migraine.
