Today's barometric pressure in Waco, 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 Waco...
Waco sits on the Brazos River between the Dallas and Austin metros, in the transition from Blackland Prairie to Hill Country. Pressure averages 999 hPa, and the city's position in the central Texas corridor puts it under the path of nearly every front that crosses the state.
Worst season for migraines: January through March. Fronts crossing central Texas in the cool months move the barometer furthest. Spring layers severe convection on top, as those same fronts begin interacting with deeper Gulf moisture pushing north.
Common triggers in Waco: repeated frontal boundary oscillation, Gulf moisture return after dry spells, spring severe convection along the I-35 corridor. Central Texas sits where the humid east and the dry west meet, and the boundary moves back and forth across Waco repeatedly through the cool season. That means the city experiences more frontal passages than places further in either direction, each one carrying a measurable barometric step even when no storm develops.
Typical pressure: Waco averages 999 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 987 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: Waco is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Waco weather trigger migraines?
Yes. Waco 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 repeated frontal boundary oscillation, Gulf moisture return after dry spells, spring severe convection along the I-35 corridor.
What time of year are migraines worst in Waco?
In Waco 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 Waco?
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 Waco 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.
