Why You Might Get More Migraines in the Summer and What You Can Do About It
Do your migraine attacks spike in the summer? You’re not alone.
Many people notice more frequent or intense headaches during the warmer months. And while summer weather can’t cause migraine, it can tip the scales for those already vulnerable.
At Haven Headache & Migraine Center, we often hear patients say:
“I always get more headaches when it’s hot out.”
“Storms make my head throb.”
“I feel worse on humid days.”
Here’s what we know and what you can do to prevent summer migraine attacks.
What Makes Summer a Common Trigger?
Researchers have found several possible culprits:
1. Heat and Humidity
- A 2024 study found a 6% increase in headache frequency for every 10°F temperature rise.
- Humid days may make your pain-sensing nerves more active.
2. Bright Sunlight
- Intense light can overstimulate the visual cortex, especially in people with migraine.
- Squinting and eye strain add fuel to the fire.
3. Dehydration and Electrolyte Loss
- You sweat more in summer, losing water and key minerals.
- This can change how your brain processes pain.
4. Air Pressure Swings
- Thunderstorms or sudden weather changes often come with drops in barometric pressure.
- This may disrupt blood vessels or sinuses and trigger attacks.
5. Air Pollution
- Summer smog and ozone levels may irritate nerves linked to migraine.
How You Can Protect Yourself
Try these practical steps to prevent weather-related migraine attacks:
- Hydrate consistently. Aim for at least 8–10 glasses of water a day.
- Replenish electrolytes. Use drinks like Pedialyte or LMNT after sweating.
- Limit sun exposure. Wear polarized sunglasses and a wide-brimmed hat.
- Watch the weather. If storms often trigger you, talk to your doctor about pre-treatment strategies.
- Track your symptoms. Use a headache diary to spot patterns and triggers.
- Consider preventive meds. If you're having attacks more than once or twice a week, preventive treatment might help.

Weather is just one piece of the migraine puzzle. Many patients experience a mix of triggers that stack up—like poor sleep, hormonal shifts, skipped meals, or stress.
