Quick temperature changes. Bright light. Weather changes. Wearing something tight-fitting on the head. Large changes in stress level. Caffeine withdrawal is a big one. Getting 10 hours of sleep (first night) then 5-6 hours of sleep (second night) is a common cause for me. I think the #1 underlying cause for me has been not getting enough hydration (or having electrolyte imbalances), though. As I've upped my daily fluid intake, they are occurring less often in general. Though, it's changed over time. At one point my most common trigger was stress. Since I've changed jobs, that also has helped reduce the frequency, very noticeably (was getting multiple a week at a stressful/hated job) It's odd because different days, different pain meds seem to work better. Aleve/Naproxen has the best overall efficacy for me, though. That, and/or putting something cold on my face and neck and being in a darker room.
