Today's barometric pressure in Cheyenne, 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 Cheyenne...
Cheyenne sits at 1,856 metres on the high plains, the highest city in this dataset and one of the windiest in the country. Baseline pressure near 814 hPa is the lowest measured here, and March rather than midwinter is its most volatile month.
Worst season for migraines: March, February and April. Spring stands out because that is when upslope storms are most productive along the Front Range, drawing moisture west against the mountains. March routinely delivers the year's heaviest snow along with its steepest pressure falls.
Common triggers in Cheyenne: spring upslope storm development, near-constant high plains wind, the lowest baseline pressure of any city here. Wind is close to constant on the Laramie plains, and Cheyenne records some of the highest sustained average wind speeds of any US city. At 1,856 metres the baseline pressure sits nearly 200 hPa below sea level readings, so residents already live at a reduced-pressure baseline before any weather arrives. Ground blizzards, in which existing snow is lifted by wind without new snowfall, are a distinctly local hazard.
Typical pressure: Cheyenne averages 814 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 797 hPa. Swings of 7-10 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Cheyenne is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Cheyenne weather trigger migraines?
Yes. Cheyenne experiences 7-10 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include spring upslope storm development, near-constant high plains wind, the lowest baseline pressure of any city here.
What time of year are migraines worst in Cheyenne?
In Cheyenne the most barometrically volatile stretch of the year falls in March, February and April. That is when weather is most likely to play a part, if weather is a trigger for you at all. See when migraine weather season starts across the U.S.
Is there a barometric pressure headache forecast for Cheyenne?
This page works as one. Many people call a headache that arrives with a weather change a barometric pressure headache, and this forecast tracks the pressure drops, humidity and temperature swings behind that idea. The score covers the next 24 hours in Cheyenne and the chart shows the next 48. It is built on migraine research, so treat it as a rough guide for other headaches. A sudden, severe headache needs urgent medical care, whatever the weather.
