For me it's lack of sleep triggering migraines. If I go a few of days without enough sleep (going to bed late, being kept awake by kids, jetlag etc) then I often get a migraine. Maybe there might some extra factor doing the real triggering such as the weather, etc, but I have noticed a clear correlation between lack of sleep and migraine. Traveling to different continents for business trips often triggered a migraine at the end of the week. If I'm working too much too late inot the nights for several days then I often get a migraine. If I sleep poorly and wake up often due to my kids having a period of bad sleep, sickness etc, then I often have a migraine after a few days of this. Drinking alcohol can also contribute as it makes the sleep less good and efficient.
