Today's barometric pressure in Baltimore, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Baltimore's Chesapeake Bay proximity creates a maritime influence that modulates but doesn't eliminate pressure swings. The mid-Atlantic storm track runs directly over the city, bringing frequent weather system passages especially in winter and spring.
Worst season for migraines: October through April. Baltimore's Inner Harbor location subjects the city to both coastal storms tracking up the Atlantic and continental systems sweeping east. Nor'easters are the biggest pressure events, but the Chesapeake Bay also generates local weather effects that create smaller, more frequent pressure variations.
Common triggers in Baltimore: nor'easter pressure drops, Chesapeake Bay moisture surges, summer heat dome events with high humidity. Baltimore sits at the head of the Chesapeake Bay, the largest estuary in the US. The bay's warm waters fuel moisture-laden air that flows over the city, and the Patapsco River valley channels this moisture into the downtown basin. The city's position between the bay and the Piedmont foothills creates a convergence zone where marine and continental air masses collide frequently.
Typical pressure: Baltimore averages 1015 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 996 hPa. Swings of 12-18 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Baltimore weather trigger migraines?
Yes. Baltimore experiences 12-18 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include nor'easter pressure drops, Chesapeake Bay moisture surges, summer heat dome events with high humidity.
What time of year are migraines worst in Baltimore?
In Baltimore the most barometrically volatile stretch of the year falls in October through April. That is when weather is most likely to play a part, if weather is a trigger for you at all.
How do I track migraine triggers in Baltimore?
Use MigrAid to log your attacks with one tap. The app automatically records barometric pressure, temperature, and humidity at the time of each migraine, then finds patterns between your attacks and Baltimore's weather conditions over time.

Is it really the weather?
Weather gets blamed for a lot of migraines, but it's hard to know if it's really behind yours. The MigrAid app saves the barometric pressure with every migraine you log, so after a few weeks you can see whether Baltimore's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
