48-hour migraine risk based on barometric pressure, humidity, and temperature changes in New Orleans.
New Orleans' near-sea-level elevation and Gulf proximity mean the city is highly responsive to tropical weather patterns. Humidity regularly exceeds 90%, and the subtropical climate produces frequent thunderstorms with accompanying pressure fluctuations.
Worst season for migraines: January through March. Cool-season fronts pushing down to the Gulf coast supply nearly all of the year's measurable pressure movement. Once summer arrives the pattern flattens into months of heat and humidity broken only by afternoon convection.
Common triggers in New Orleans: hurricane season pressure collapse, near-permanent humidity above 75 percent, daily afternoon convection off the Gulf. Sitting at or below sea level between the river and Lake Pontchartrain, New Orleans is surrounded by water on nearly every side, which keeps humidity high year-round and the daily temperature range narrow. Ordinary weather barely moves the barometer here, so the city's defining barometric events are tropical: an approaching hurricane can drop pressure further in a day than the whole rest of the year combined.
Typical pressure: New Orleans averages 1015 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 1005 hPa. Swings of 4-8 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can New Orleans weather trigger migraines?
Yes. New Orleans experiences 4-8 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include hurricane season pressure collapse, near-permanent humidity above 75 percent, daily afternoon convection off the Gulf.
What time of year are migraines worst in New Orleans?
In New Orleans the most barometrically volatile stretch of the year falls in January through March. That is when weather is most likely to play a part, if weather is a trigger for you at all.
How do I track migraine triggers in New Orleans?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and New Orleans's weather conditions over time.
