Today's barometric pressure in Philadelphia, a 48-hour pressure chart, and a migraine risk score based on pressure drops, humidity, and temperature changes.
Philadelphia sits in the path of weather systems moving up the East Coast, experiencing frequent pressure fluctuations. The Delaware Valley's mix of coastal and inland weather patterns creates unpredictable conditions for migraine sufferers.
Worst season for migraines: October through April. Philadelphia's Delaware Valley location puts it in the primary East Coast storm track. Nor'easters and coastal lows track directly over or near the city multiple times per season, each bringing sustained pressure drops that can last 24-48 hours.
Common triggers in Philadelphia: coastal storm systems, rapid temperature changes during frontal passages, high humidity in summer heat waves. The Philadelphia metro area sits in a transition zone between maritime and continental climates. This means the city gets hit by both coastal storms and interior weather systems, doubling the number of significant pressure events compared to cities firmly in one climate zone.
Typical pressure: Philadelphia 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 Philadelphia weather trigger migraines?
Yes. Philadelphia 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 coastal storm systems, rapid temperature changes during frontal passages, high humidity in summer heat waves.
What time of year are migraines worst in Philadelphia?
In Philadelphia 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 Philadelphia?
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 Philadelphia'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 Philadelphia's swings actually line up with your attacks, and get a heads-up on days that match your pattern.
