Research shows that a sudden change in temperature, usually associated with a cold front, or changes in atmospheric pressure, like a thunderstorm, can trigger a migraine attack.1,2 This is true for many people with migraine following exposure to sudden weather changes.1,3
In one study, 43% of patients cited weather changes as a key factor in their migraines. 38% also reported that bright sunlight triggered their headaches.2
To determine if the weather is a factor, try keeping a log of migraine headaches and the accompanying conditions.
Record the weather for a few weeks or months (depending on the frequency of the headaches) remembering to take note of the temperature, the amount of time spent outdoors, whether there was bright sunlight or clouds and any sudden changes in the weather
Then, look for patterns in any of the recorded factors to find out what triggers the migraine symptoms. Modifying these factors may substantially reduce the frequency of migraines occurring.4 As an example, if bright light appears to be a trigger factor for a migraine, consider staying indoors on sunny days or invest in a highly-tinted pair of sunglasses. If it is sudden changes in temperature, make sure you are always dressed appropriately and try moving from one extreme to the other more gradually.
