Have you ever wished there was an early warning system for incoming headaches—without the loud sirens—so you could take cover and avoid a pounding storm inside your skull?

Well, there is such a thing. Just watch the forecast for warmer weather.

Scientists investigated more than 7,000 emergency room visits for severe headaches of all kinds, looking for links to weather. The culprit they uncovered was a rise in temperature about a day before the hospital visit.

Spring, summer, fall, and winter—no matter the season—rising mercury was a real pain for headache-prone people.

So if you can't change the weather—what can you do?

Researchers recommend a headache diary. Track the weather along with other possible culprits, such as sleep and exercise changes, alcohol, and foods like cured meats.

That way, you won't blame, say, the chocolate truffles you ate on your anniversary, when a spike in temperature the day before was really the reason.

Also, if you know a warm front is coming in, make an extra effort to avoid additional things that trigger your headaches. That way, warming weather can be less of a headache and more of a walk in the park.
