Today's barometric pressure in Las Cruces, 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 Las Cruces...
Las Cruces sits at 1,191 metres in the Mesilla Valley with the Organ Mountains rising sharply to the east. Pressure averages 884 hPa, and the Chihuahuan Desert setting means aridity is a constant rather than a seasonal condition.
Worst season for migraines: January through March. Cool-season Pacific systems crossing New Mexico account for most measurable pressure change. Spring brings the windiest stretch of the year, when dust lifted off the basin floor reduces visibility for hours at a time.
Common triggers in Las Cruces: chronic sub-15 percent humidity, abrupt July monsoon moisture reversal, spring dust storms across the basin. Southern New Mexico humidity often sits below 15 percent for weeks, making dehydration a persistent background factor entirely separate from the barometer. The monsoon arriving in July reverses that abruptly, and the sudden jump in moisture is itself a noticeable change. The Organ Mountains also generate local downslope winds that do not appear in the regional forecast.
Typical pressure: Las Cruces averages 884 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 874 hPa. Swings of 6-8 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Las Cruces is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
