Today's barometric pressure in Montgomery, 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 Montgomery...
Montgomery sits on the Alabama River at the edge of the Black Belt, a band of dark prairie soil crossing the state. Pressure averages 1008 hPa with a narrow 5 to 8 hPa swing range, and humidity rather than barometry dominates much of the year.
Worst season for migraines: January through March. Winter and early spring bring the frontal passages that account for most measurable pressure change. Through the long summer, conditions settle into a repetitive pattern of heat, humidity and afternoon convection with little large-scale movement.
Common triggers in Montgomery: sustained summer humidity above 75 percent, stalled fronts along the coastal plain, prolonged high heat index periods. Central Alabama humidity regularly holds above 75 percent from May into September, and heat index values exceed 40C for weeks at a time. For many people here the dominant weather trigger is that sustained load rather than any discrete pressure event. When fronts do arrive in winter, they often stall along the Gulf coastal plain, drawing out the transition over several days.
Typical pressure: Montgomery averages 1008 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 998 hPa. Swings of 5-8 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
2026 index: Montgomery is not one of the 100 metros ranked in our 2026 U.S. Migraine Risk Index, which shows how they compare.
Can Montgomery weather trigger migraines?
Yes. Montgomery experiences 5-8 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include sustained summer humidity above 75 percent, stalled fronts along the coastal plain, prolonged high heat index periods.
What time of year are migraines worst in Montgomery?
In Montgomery 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 Montgomery?
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 Montgomery 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.
