48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Henderson.
Henderson sits at 569 metres in the southeastern corner of the Las Vegas valley, closer to Lake Mead than the Strip. Pressure averages 948 hPa, and the surrounding ranges hold the valley's air in place until a system is strong enough to move it.
Worst season for migraines: January and March, with February close behind. Systems strong enough to clear both the Sierra and the Spring Mountains bring the main cool-season changes. Monsoon moisture in late summer adds isolated but intense convective events over the valley.
Common triggers in Henderson: basin stagnation with accumulating particulates, monsoon convection over the valley, single-digit humidity through the warm months. Ringed by mountains on every side, the Las Vegas valley is a closed basin where air stagnates readily and pollutants accumulate during calm periods. Henderson's position on the eastern side means it catches downslope flow off the McCullough Range. Between these effects and humidity that often stays in single digits, dehydration and air quality both act alongside barometric change.
Typical pressure: Henderson averages 948 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 938 hPa. Swings of 5-9 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Henderson weather trigger migraines?
Yes. Henderson experiences 5-9 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include basin stagnation with accumulating particulates, monsoon convection over the valley, single-digit humidity through the warm months.
What time of year are migraines worst in Henderson?
In Henderson the most barometrically volatile stretch of the year falls in January and March, with February close behind. 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 Henderson?
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 Henderson'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 Henderson's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
