48-hour migraine risk based on barometric pressure, humidity, and temperature changes in Oakland.
Oakland's position opposite the Golden Gate puts it in the path of marine air funneling through the only sea-level gap in the coastal range. Pressure holds near 1014 hPa most of the year, then drops to about 1004 when atmospheric rivers land.
Worst season for migraines: January through March. Atmospheric river events concentrate in the first three months of the year, delivering the steepest declines the East Bay sees. Summer brings the opposite problem: months of near-total pressure flatness broken only by fog cycles.
Common triggers in Oakland: atmospheric river landfalls, afternoon marine push through the Golden Gate, autumn Diablo wind reversals. Marine air funnels inland every afternoon through the gap in the hills at the Golden Gate, producing a daily pressure and temperature oscillation that inland cities do not experience. Oakland sits at the receiving end of that flow, and the hills above the city can differ from the flats by several degrees and a measurable fraction of a millibar.
Typical pressure: Oakland averages 1014 hPa at rest, measured at the city's own elevation rather than corrected to sea level, and storm systems can push readings down to 1004 hPa. Swings of 4-8 hPa over 24 hours are common during active weather and fall within the range most associated with pressure-triggered migraines.
Can Oakland weather trigger migraines?
Yes. Oakland experiences 4-8 hPa barometric pressure swings, and research shows pressure drops are one of the most common migraine triggers. The city's specific patterns include atmospheric river landfalls, afternoon marine push through the Golden Gate, autumn Diablo wind reversals.
What time of year are migraines worst in Oakland?
In Oakland 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.
How do I track migraine triggers in Oakland?
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 Oakland's weather conditions over time.
