Weather and migraine
Many people with migraine say changes in the weather, such as a shift in air pressure, seem to come before their attacks. The Migraine Trust and the American Migraine Foundation both list weather changes as a common trigger.
Research results are mixed: some studies link falling or changing pressure to attacks in some people, while others find no clear pattern. A diary of your own attacks can show whether it seems to apply to you.

About migraine weather
What is migraine weather?
It's what many people with migraine call the weather they keep an eye on, most often a change in air pressure. These pages show the air pressure for your city, hour by hour. They show the weather only: they can't tell you when an attack will come.
What counts as a big drop in air pressure?
On these pages, a fall of more than 3 hPa within 24 hours is marked on the chart, with its size and times. Up to 3 drops are shown each week, the largest first. If there's none, the page says the pressure stays fairly steady.
What is hPa?
Hectopascals, the unit weather services use for air pressure. At sea level it's usually between about 980 and 1,040 hPa, and 1,013 hPa is the standard value.
Where does the data come from?
MET Norway's forecast, the same one the Looma app uses, refreshed every 6 hours. MET Norway only forecasts ahead, so the past 2 days on each chart are its earlier forecasts for those hours, not measurements.
How do I compare air pressure with my attacks?
Write down each attack, then look at the pressure for the same days. The free headache diary works on paper. Turn on air pressure in Looma and it's saved with each attack you log on iPhone. Premium shows how many came after a big change.
