Headache Forecast — What the Pressure Is Doing
Barometric pressure drops are one of the most reliable migraine triggers. We track the pressure in thirty-two cities across four world regions, blend it with geomagnetic storms (Kp) and Schumann resonance activity, then tell you how risky today looks.
Each dot is one city. Color tracks local headache risk.

How the Risk Score Is Built
The score combines three signals that reach your nervous system through different paths. Together they explain more than any single metric.
Pressure change
A drop of 5 hPa or more inside 24 hours is the textbook migraine setup. Bigger or faster drops score higher.
Geomagnetic (Kp)
Kp 5 and above means a geomagnetic storm. People with autonomic sensitivity often feel these days before weather reports mention them.
Schumann resonance
When the Earth-ionosphere cavity is loud (active or storm), people describe a diffuse restlessness that stacks on top of the headache itself.

Проверить статусWhat Pressure Actually Does to Your Head
Atmospheric pressure at sea level averages around 1013 hPa. Your body is tuned to that number in a quiet way. The sinuses, the middle ear, and fluid-filled spaces around the brain all sit at the same pressure as the air outside — until the air changes faster than your tissues can equalise.
When a weather front arrives and the pressure drops several hPa in a few hours, the spaces inside your head expand slightly to match the lower outside pressure. For most people this is imperceptible. For a migraine-prone brain, it triggers the same inflammation cascade as light or stress: the trigeminal nerve fires, blood vessels in the dura dilate, and the headache builds.
The pattern most reported is a frontal or temporal headache that starts a few hours before the weather visibly changes, peaks as pressure bottoms out, and fades as pressure rebuilds. That is why you sometimes know rain is coming before the clouds arrive.
Who Feels This Most
Migraine sufferers are the most documented group — roughly half report weather as a trigger, with barometric drops as the most common pattern. But the sensitivity shows up in other ways too.
Migraine sufferers
Especially those with chronic migraine or menstrual migraine — hormonal and atmospheric triggers often stack.
Sinus-prone people
Pressure changes make blocked sinuses noisy. This is a pressure headache, not a sinus infection, but it feels the same in the face.
Joints and old injuries
Scar tissue and arthritic joints have less give, so pressure swings create small forces. That is the "my knee tells me it will rain" thing — it is real.
Cluster headache patients
Seasonal clusters line up with the equinox pressure swings. Not the only factor, but a contributing one.
Autonomic-sensitive nervous systems
People with POTS, fibromyalgia, or long-COVID often describe weather sensitivity even when they do not get headaches — fatigue and brain fog instead.
What Actually Helps When Pressure Drops
Drink water earlier than usual
Dehydration magnifies every migraine trigger. When the forecast shows a drop coming, start drinking before you feel thirst, not after.
Caffeine timing matters
A small dose of caffeine constricts blood vessels and can blunt a pressure-related headache if you take it early. Too much, or too late, makes it worse.
Protect sleep the night before
Short sleep lowers the threshold for every trigger. If you see a storm coming in the next 24 hours, push bedtime earlier rather than later.
Schedule gentler tasks
Pressure-sensitive people have better and worse days. Use the forecast to front-load demanding work on stable days, save admin and rest for storm days.

ВоспроизвестиQuestions People Ask
How big does the pressure drop need to be to trigger a headache?
The classic threshold is a 5-hPa drop within 24 hours, but there is huge individual variation. Some people feel changes as small as 2-3 hPa, others need 8-10. Track your own pattern for a few weeks and the number will become clear.
Is it the drop itself, or the low pressure, that triggers me?
For most people, it is the rate of change. Stable low pressure (in high-altitude cities, for example) is usually tolerated well. It is the transition — the weather front moving through — that lights up the trigeminal nerve.
Can Kp storms really add to pressure headaches?
The correlation is weaker than pressure alone, but real. On days with both a pressure drop and a G1 or bigger geomagnetic storm, people prone to both report more intense symptoms than either alone would suggest. The nervous system sums inputs.
Why include Schumann resonance when it is not a mainstream medical trigger?
Because some people track it and report a correlation. We do not claim medical authority — we show the data and let you see if the pattern holds for you. If you never feel a difference, ignore that component.
Does the risk score work for my specific city?
The global score is a median of eight reference cities. Your local pressure may be different today. Find the nearest monitored city in the grid above — if you are within a few hundred kilometres, the trend is usually similar. A local weather app gives you your exact reading.
What do I do if today is high-risk?
Nothing dramatic — just tip the day toward the gentler side. Hydrate early, avoid skipped meals, go easy on alcohol and heavy lunches, prioritise sleep, keep rescue medication accessible. Small choices stack up.
