Migraine & Headache Weather Risk Forecast
Check pressure changes, humidity, heat, wind, rain, and UV conditions that may be worth tracking with your headache diary.

What is a migraine weather forecast?
This tool looks at local forecast conditions that some people with migraine or headache disorders choose to track: barometric pressure changes, heat, humidity, wind, rain or storm signals, and bright sun or UV.
The result is a weather-watch level. It is not a prediction that a migraine attack will happen. It is a planning and diary aid so you can compare forecast changes with your real symptoms over time.
Weather triggers are personal
Weather may be relevant for some people, but evidence is mixed and weather often stacks with sleep disruption, stress, skipped meals, dehydration, hormones, or medication patterns. Your diary pattern matters more than one forecast.
Can weather trigger migraine or headache?
Mayo Clinic lists bright sunlight, extreme heat or cold, sun glare, high humidity, dry air, windy or stormy weather, and barometric pressure changes among weather-related migraine triggers reported by some people. The American Migraine Foundation also notes that seasonal changes, pressure shifts, heat, humidity, and glare may matter for some patients.
Researchers continue to study the relationship. A 2024 review, Whether Weather Matters with Migraine, summarizes that weather is commonly reported but not universally predictive, which is why this tool uses cautious “worth tracking” language rather than diagnostic or predictive claims.
Which weather changes may matter?
Pressure changes
A pressure rise or drop over several hours may be more useful to track than one pressure value.
Heat and humidity
Hot, humid conditions may increase dehydration risk or disrupt routines for some people.
Storms and rain
Storm systems can combine pressure changes, wind, rain, and light changes.
Wind and gusts
Windy conditions may stack with temperature changes, allergens, or sensory discomfort.
Bright sun or UV
Sun glare and bright light can be relevant for people with light sensitivity.
Trigger stacking
Weather may matter most when sleep, meals, hydration, stress, or hormones are also unstable.
How to use this forecast with a migraine diary
Save the forecast only when it is useful, then log whether a headache actually happened. After several weeks, compare weather-watch days with non-weather days before assuming a weather trigger.
What to track after a high weather-watch day
- Headache start time and duration
- Severity and symptoms
- Medication used and response
- Sleep, meals, hydration, caffeine, and stress
- Menstrual-cycle timing if relevant
- Whether the same weather pattern repeats with symptoms
When to seek medical help
Speak with a clinician if headaches are frequent, severe, changing, or disabling. Seek urgent care for sudden worst headache, weakness, confusion, fainting, seizure, vision loss, fever/stiff neck, head injury, pregnancy/postpartum headache, or a very different headache pattern.
How this connects with Migraine Journey
Privacy and location use
Browser location is optional. You can search by city or postal code instead. Weather providers receive location coordinates for the forecast, but not your migraine notes, symptoms, medications, or diary data.
Frequently Asked Questions
Can weather forecasts predict migraine attacks?
No. Weather may be a trigger for some people, but this tool cannot predict, diagnose, prevent, or treat migraine. It only highlights weather conditions worth tracking.
Why does this tool focus on pressure change?
Many people track barometric pressure because changing pressure is commonly reported around weather-sensitive migraine patterns. Evidence is mixed, so diary confirmation matters more than one forecast.
Does a high weather-watch level mean I will get a headache?
No. A high weather-watch level means several forecast factors are changing or stacking. Your sleep, meals, stress, hydration, hormones, and personal history may matter just as much.
Should I change medication because of this forecast?
No. Do not start, stop, or change migraine or headache medication based on this tool. Follow your clinician’s advice and use the forecast as a planning and tracking aid.
Is my location saved?
Location is used to fetch local weather. Guest saved results stay in this browser/device, and precise browser coordinates should only be saved if you choose to save a forecast summary.
