During a storm, cold and warm air collide, creating an extreme difference in barometric (or air) pressure. This creates the elements of a thunderstorm, like wind and rain. The change in barometric pressure may be what triggers your headache, whether that is a migraine, tension-type headache, or a sinus headache.

Why does barometric pressure cause headaches?

Headaches can occur when pressure changes affect the small, confined, air-filled systems in the body, such as those in the ears or the sinuses. Changes in atmospheric pressure can create an imbalance in the pressure within the sinus cavities and the structures and chambers of the inner ear, resulting in pain.
