Migraine & arthritis weather forecast: how Weather24 rates today’s weather load

In short: no app can forecast a migraine — but it can forecast the weather that studies link to headaches and joint pain: a fast pressure drop ahead of a front, humid air after dry days, big temperature swings. The Weather24 app scores these factors for your location every hour on a 0–10 scale and tells you why.

Meteo-sensitivity hour by hour for your location, with the reasons — in the Weather24 app.

01

What weather-sensitive people actually feel

Plenty of people say they can feel the weather coming — headaches, joint pain, fatigue, poor sleep. Research is cautious, but four weather factors keep showing up:

Strongest link Humidity

Especially when damp air arrives after dry days.

UK study “Cloudy with a Chance of Pain”, 2,658 participants.

Ahead of a front Pressure drop

Migraine attacks clustered at drops of 6–10 hPa (≈0.2–0.3 inHg); a fast fall hits harder than a slow one.

Japanese studies (Okuma 2015, Kimoto 2011), small groups.

Versus yesterday Temperature swings

Big changes over 1–3 days, including the felt temperature — like the cold wind behind a front.

Weaker Low pressure + wind

Low pressure together with stronger wind — weaker than humidity, but measurable.

This is weather information, not medical advice. If symptoms are severe or new, talk to a doctor.

How the Weather24 app rates the weather load

  1. Four factors, not one. The app scores humidity, low pressure with wind, temperature swings and pressure change — the same factors as in the studies above.
  2. Compared with your normal. Everything is measured against what is usual where you are: pressure against the 30-day average, humidity against the days before.
  3. Fronts ahead of time. When pressure starts falling and rain follows, the app spots an approaching front — before the rain, which is when weather-sensitive people feel it. The card then says something like “front approaching, rain in 3 h”.
  4. A 0–10 score, every hour. The strongest factor sets the score and each other noticeable factor adds to it, because coinciding factors are the hardest. Below 4 is “Low risk”, from 4 “Moderate risk”, from 7 “High risk”.
  5. With the reasons. Instead of a bare number you see why: “pressure falling by 0.24 inHg”, “humidity jumped to 92%”, “temperature swing 16°”.

Check once in the morning. The hourly curve shows when today’s weather load peaks, so you can plan around it.

Pressure, made simple

Sea-level pressure in the US usually sits between about 29.5 and 30.5 inHg (999–1033 hPa); the standard is 29.92 inHg (1013 hPa). A single reading says little — what matters is direction and speed. A drop of 0.09 inHg (3 hPa) or more in three hours counts as fast and usually means a front is on its way. In the app you get the Pressure over the day chart, the Rapid pressure drop warning and a pressure map layer with highs and lows.

Meteo-sensitivity in the Weather24 app

The Meteo-sensitivity card shows hour by hour how hard today’s weather is on weather-sensitive people and why — humidity, pressure change, wind and temperature swings. Plus pressure over the day and a Rapid pressure drop warning.

Frequently asked questions

Is the barometric pressure affecting people today?
The biggest 24-hour pressure change among major US cities right now is in Boston: +0.25 inHg (+8.4 hPa) — a sharp swing of the kind weather-sensitive people often notice. For your exact location, the Meteo-sensitivity card in the Weather24 app rates the weather load hour by hour.
Is there a migraine weather forecast?
Nobody can forecast a migraine. What can be forecast is the weather that studies link to headaches — mainly a pressure drop ahead of a front and a jump in humidity. The Weather24 app scores exactly those factors for every hour of the day, so you can see when the weather load will peak.
What barometric pressure causes headaches?
Research points to the change, not a single number. In a Japanese headache-diary study (Okuma et al., 2015), migraine attacks clustered when pressure fell 6–10 hPa (about 0.18–0.30 inHg) below the standard 1013 hPa. The study was small, so treat it as an observation, not a threshold. This is weather information, not medical advice.
How does the Weather24 app calculate meteo-sensitivity?
From four weather factors with the best evidence: humidity, low pressure with wind, temperature swings and pressure change — each compared with what is usual for your location over the last 30 days. The strongest factor sets a score from 0 to 10, and each additional noticeable factor raises it.
