United States
New York
NY, United States
Highest risk: October–April during nor'easter season. Secondary risk: summer afternoon thunderstorms.
Los Angeles
CA, United States
Highest risk: October–December during Santa Ana wind season. Otherwise among the most stable major US cities.
Chicago
IL, United States
Highest risk: March–May and September–November. Lake-effect weather amplifies local pressure variation beyond regional forecasts.
Houston
TX, United States
Highest risk: June–November during hurricane season and frontal collision events.
Phoenix
AZ, United States
Highest risk: July–September monsoon season. Otherwise one of the most stable pressure environments in North America.
Philadelphia
PA, United States
Highest risk: November–March nor'easter season, with secondary risk from summer convective storms.
San Antonio
TX, United States
Highest risk: October–February during Blue Norther frontal passages. Summer heat domes also create persistent low-pressure periods.
San Diego
CA, United States
Generally low risk year-round. Mild Santa Ana influence in fall is less severe than Los Angeles.
Dallas
TX, United States
Highest risk: March–May during severe weather season, and October–December during fall frontal passages.
Austin
TX, United States
Highest risk: March–May. Summer heat domes create prolonged low-pressure conditions.
Miami
FL, United States
Highest risk: August–October during peak hurricane season. Otherwise relatively stable.
Denver
CO, United States
Year-round risk due to rapid weather changes off the Rockies. Chinook wind events in winter create sudden warming and pressure shifts.
Seattle
WA, United States
Highest risk: October–March. Seattle's prolonged low-pressure winters are a well-known challenge for migraineurs.
Boston
MA, United States
Highest risk: December–March. Coastal positioning amplifies nor'easter intensity versus inland cities.
Atlanta
GA, United States
Highest risk: spring frontal passages and winter ice storm events.
Minneapolis
MN, United States
Highest risk: November–April. Alberta Clippers arrive quickly with little lead time.
Portland
OR, United States
Highest risk: October–March. Gorge wind events add a local pressure dimension on top of regional frontal patterns.
Nashville
TN, United States
Highest risk: March–May tornado season and November–February frontal passages.
Charlotte
NC, United States
Highest risk: November–March nor'easter influence and August–October tropical system remnants.
International
London
England, United Kingdom
Highest risk: October–March. Roughly two frontal passages per week in winter means constant pressure variability.
Toronto
Ontario, Canada
Highest risk: November–March. Lake Ontario amplifies local weather extremes.
Sydney
NSW, Australia
Highest risk: April–September during East Coast Low season (Australian autumn/winter).
Melbourne
VIC, Australia
Year-round risk. Southern Ocean fronts arrive with little warning in any season.
Dublin
Leinster, Ireland
Highest risk: October–March. Dublin's sustained low-pressure winters are among the most prolonged in any major English-speaking city.
Vancouver
BC, Canada
Highest risk: October–February. Persistent low-pressure systems can linger for 5–10 days.
About These Forecasts
Each city page shows real-time barometric pressure sourced from Open-Meteo, a high-accuracy meteorological API that aggregates data from national weather services including NOAA, ECMWF, and Meteo-France. Pressure readings are sea-level corrected, consistent with the values used in migraine research.
Risk levels are calculated based on two primary factors: current pressure (low pressure below 1000 hPa raises risk) and 24-hour pressure change (drops greater than 5 hPa are linked to elevated migraine onset in research).
These forecasts reflect population-level risk based on published research thresholds. Your personal sensitivity may differ. Track your own history in the Migraine Trail app to understand your specific weather patterns.
