Sinus and ear pressure when the weather changes
Short answer
Your middle ears and sinuses are pockets of air that have to keep up with the pressure around you. When the outside pressure changes faster than they can equalise, usually because a cold or an allergy has narrowed the passages, you feel fullness, popping or pain. Weather changes are small and slow next to a flight: even a rapidly deepening storm is defined by a fall of roughly 18 to 24 hPa in 24 hours at its centre, while an airliner cabin may sit about 260 hPa below sea-level pressure. So weather alone rarely produces the ear trouble of a landing, but congested ears and sinuses notice smaller changes. And many “sinus headaches” turn out to be migraine: in a study of 2,991 people with that label, 88% met criteria for migraine-type headache.
How ears and sinuses keep up with pressure
The middle ear sits behind the eardrum and connects to the back of the nose through the Eustachian tube. Normally the air pressure inside matches the air outside. Swallowing or yawning opens the tube briefly and lets air in or out, which is why your ears pop on a plane. If the tube is blocked, the pressure on each side of the eardrum differs. MedlinePlus calls the result ear barotrauma: discomfort, a sense of fullness, slightly muffled hearing and sometimes dizziness.
The sinuses are air-filled spaces in the bones of the face that drain into the nose through small openings. When those openings swell shut with a cold or hay fever, the air trapped inside cannot follow outside changes as easily. The same principle explains why congestion makes both ear and sinus pressure more likely.
How big is a weather change, really?
It helps to put weather into perspective. Approximate pressure changes for common situations:
| Situation | Change | Over |
|---|---|---|
| A major change in Barometric Pressure Tracker | 6 hPa | 6 hours |
| NOAA's threshold for a “bomb” storm at 60° latitude (storm centre) | 24 hPa | 24 hours |
| Driving 300 m (about 1,000 ft) up a mountain road | about 35 hPa | minutes |
| Airliner cabin at the 8,000 ft limit allowed by US rules | about 260 hPa below sea level | the climb |
The mountain-road and cabin figures come from the standard atmosphere, in which pressure at 8,000 feet is roughly 750 hPa. US certification rules require pressurised cabins to stay at a cabin altitude of no more than 8,000 feet in normal operation.
So a typical weather front is a gentle, slow change by comparison. That is why most people never feel it in their ears, and why those who do usually have something narrowing the passages already. If your ears feel blocked on stormy days, it is worth asking whether you also have congestion at those times.
Sinus pressure, or a migraine with sinus symptoms?
Pressure across the forehead and cheeks feels like a sinus problem, but it is very often part of a migraine. Schreiber and colleagues screened 2,991 people in the US who had a history of “sinus” headache, either self-described or diagnosed by a doctor, with no signs of infection and no previous migraine diagnosis. 88% met the criteria for migraine-type headache. The sinus-area symptoms they reported most were sinus pressure (84%), sinus pain (82%) and nasal congestion (63%).
This matters for weather too. If your “sinus pressure” days line up with pressure changes, they may belong to the same picture as weather-related migraine discussed in our headache guide. A doctor can tell the two apart, and the right treatment depends on which it is. The study's authors concluded that in recurring headaches without fever or pus-like discharge, sinus-area symptoms may be part of migraine, so it should be considered.
Researchers have also suggested the reverse route: that pressure differences in the sinuses might contribute to headache in people with structural sinus problems, by a mechanism similar to the facial pain some people feel on a descending plane. This is a hypothesis listed in a 2025 review, not an established finding.
What helps with ear pressure
MedlinePlus lists simple ways to open the Eustachian tube and relieve pressure:
- chew gum or suck on a sweet;
- yawn;
- breathe in, then gently breathe out while holding your nostrils closed and keeping your mouth shut;
- on a flight, stay awake while the plane prepares to land and repeat these steps.
If self-care does not ease the discomfort within a few hours, or the problem is severe, see a health professional. They may suggest a decongestant or a steroid, as tablets or a nasal spray, and antibiotics if an infection has developed. Ask a pharmacist or doctor before using a decongestant, as they are not suitable for everyone.
Tracking sinus and ear symptoms
Because a cold and a spell of changeable weather can easily coincide, it is worth recording both. A useful log for these symptoms notes:
- which symptom: sinus pressure, ear pressure, or a headache in the sinus area;
- how strong, on a consistent 1–10 scale;
- whether you had a cold, hay fever or a blocked nose that day;
- anything you took for it.
After a couple of months you can check two separate questions: do the symptoms follow big pressure changes more often than chance, and do they mostly happen when you are congested? If the second is true and the first is not, the weather may be a bystander.
When to get help
MedlinePlus advises seeing a health professional if self-care does not ease ear discomfort within a few hours or the problem is severe; hearing loss and dizziness are among the symptoms of barotrauma to mention. For the head, get prompt advice for a worsening headache with fever, a headache that reaches its peak within minutes, or any new weakness, numbness or confusion. Repeated dizziness with ear fullness and ringing can also point to an inner-ear condition such as Ménière's disease; see our vertigo guide.
