Today's barometric pressure in Plano, 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 Plano...
Plano sits on the northern edge of the Dallas metroplex where the Blackland Prairie opens toward Oklahoma. Baseline pressure near 992 hPa reflects the 203 metre elevation, and the flat terrain gives approaching fronts nothing to slow them down.
Worst season for migraines: January through March. Frontal passages between January and March produce the sharpest barometric moves. Severe weather peaks slightly later, in April and May, when the metroplex sits under the most active part of the southern plains storm track.
Common triggers in Plano: fast-moving Arctic frontal arrivals, post-frontal pressure rebound, spring supercell development. North Texas fronts often arrive faster than forecast because there is no terrain between here and the Canadian plains to slow them. Pressure can rise 10 hPa in six hours behind a front, and the rapid rebound is as much a trigger for some people as the fall that preceded it.
Typical pressure: Plano averages 992 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 979 hPa. Swings of 6-11 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Plano is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Plano weather trigger migraines?
Yes. Plano experiences 6-11 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include fast-moving Arctic frontal arrivals, post-frontal pressure rebound, spring supercell development.
What time of year are migraines worst in Plano?
In Plano the most barometrically volatile stretch of the year falls in January through March. 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 Plano?
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 Plano and the chart shows the next 48. It is built on migraine research, so treat it as a rough guide for other headaches.
