Today's barometric pressure in Houston, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Houston's subtropical humidity frequently exceeds 80%, a known migraine trigger. Gulf storms create dramatic pressure drops, and the city's heat dome effect in summer adds temperature-related stress for sensitive individuals.
Worst season for migraines: June through October. Hurricane season brings the most extreme barometric events, but Houston's humidity-driven thunderstorms create smaller pressure fluctuations nearly daily from May through September. Winter cold fronts sweeping through warm Gulf air produce sharp pressure drops as well.
Common triggers in Houston: persistent humidity above 80%, tropical storm pressure drops, rapid cold front passages in winter. Houston's subtropical climate means humidity itself is a constant baseline trigger. The city averages over 100 days per year above 90 degrees with humidity to match, creating dehydration risk that compounds weather-related migraine triggers. Gulf moisture surges can raise humidity from 60% to 95% in hours.
Typical pressure: Houston 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 990 hPa. Swings of 10-20 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Houston weather trigger migraines?
Yes. Houston experiences 10-20 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include persistent humidity above 80%, tropical storm pressure drops, rapid cold front passages in winter.
What time of year are migraines worst in Houston?
In Houston the most barometrically volatile stretch of the year falls in June through October. 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 Houston?
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 Houston's weather conditions over time.

Is it really the weather?
Weather gets blamed for a lot of migraines, but it's hard to know if it's really behind yours. The MigrAid app saves the barometric pressure with every migraine you log, so after a few weeks you can see whether Houston's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
