Weather and migraine: If you’ve ever blamed a pounding headache on the weather, you’re not imagining things. Many migraine sufferers swear they can “feel” a storm coming before it even shows up on the radar. Sounds dramatic? Maybe, but there’s real science behind it.
The pressure problem:
One of the biggest culprits is barometric pressure, which is the invisible force exerted by the air around us. When a storm rolls in and that pressure suddenly drops, some people’s bodies react in a not-so-friendly way. Blood vessels in the brain can expand or contract, nerves fire off like they’re over-caffeinated, and bam, migraine time.

It’s not always storms, either. Some people report that their migraines flare up when the weather shifts from hot to cold, or humid to dry. Imagine your brain as that friend who hates sudden changes; it just wants consistency, but the atmosphere doesn’t care.
Sun, heat, and… sunglasses?
Hot, bright days are another trigger. Ever stepped outside in July, squinted so hard your forehead hurt, and thought, “This can’t be helping”? For some, that glare and heat are the perfect recipe for a migraine attack. Dehydration doesn’t make things better. Forget to drink water, add in some direct sunlight, and you might find yourself retreating to a dark, quiet room by afternoon.
Some migraine veterans keep sunglasses in their bag year-round, even in winter. Why? Because glare off snow can be just as brutal as summer sun. Practical, if not a little inconvenient.
Rainy day blues:
Rain can be soothing for a lot of people, but not if you’re migraine-prone. The combination of pressure changes, damp air, and sometimes even mould growth can tip things over the edge. Plus, rainy days tend to trap people indoors, where stuffy air or certain smells (think damp carpet or musty corners) can add their own layer of discomfort.
So, what can you do?
Unfortunately, controlling the weather isn’t an option (yet). But there are ways to outsmart it:
- Track your patterns. Keep a simple journal. If migraines often line up with certain weather changes, you’ll spot the trend faster.
- Hydrate more than you think you need. Weather shifts are tough enough without your body being dehydrated.
- Control your environment. Fans, humidifiers and blackout curtains can make a difference when the sky outside is doing its thing.
- Talk to your doctor. If the weather consistently triggers symptoms, they might tweak your treatment plan accordingly.

Not every migraine is caused by the weather, but dismissing it as “just in your head” misses the point, because, technically, it is in your head. Weather is one of those sneaky, hard-to-control triggers, and it’s frustrating because you can’t exactly avoid it like you can certain foods or bright screens.
But here’s the good news: once you know the pattern, you can plan. Think of it less like a curse and more like a storm warning. When the clouds gather, at least you’ll know what’s coming.
