Migraine Weather Forecast by City
Check today's barometric pressure, headache weather risk, and 7-day migraine forecast for 25 major cities worldwide. Select your city to see the current pressure trend and upcoming risk.
What is a migraine weather forecast?
A migraine weather forecast shows weather conditions that may be relevant to people whose attacks are sensitive to barometric pressure, temperature, or humidity. These city forecasts use current atmospheric data to highlight pressure changes that can raise population-level headache risk.
Your personal sensitivity can be different. For a personalized migraine predictor, use the Migraine Trail weather forecast app with your own attack history, or start with the free migraine tracker.
A forecast is an estimate, not a diagnosis or a guarantee that an attack will or will not occur.

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.
