Today's barometric pressure in Provo, 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 Provo...
Provo sits at 1,387 metres between Utah Lake and the Wasatch Range, where peaks rise more than 2,000 metres directly above the valley floor. Pressure averages 862 hPa, and the enclosed valley traps air through much of the winter.
Worst season for migraines: December, February and January. December brings the most volatile conditions, driven by the season's first strong inversions alternating with Pacific systems crossing the range. Those two regimes trade places repeatedly through midwinter.
Common triggers in Provo: multi-week valley inversion episodes, abrupt inversion-clearing storms, Utah Lake effect snow bands. Utah Valley inversions rank among the most persistent in the country, holding cold air and pollution against the valley floor for weeks while the mountains above sit in clear warm air. Pressure stays high and flat during these episodes, then changes sharply when a storm finally breaks through. Lake-effect snow off Utah Lake adds a further local variable the regional forecast rarely captures.
Typical pressure: Provo averages 862 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 848 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: Provo is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
