Aching Joints Before Rain
Genuinely, presently mixed in the research — and this page won't pretend otherwise. A well-known controlled 1996 study found no statistically significant link between weather and arthritis pain. A much larger 2016 smartphone-based study of over 13,000 people found a real, if modest, correlation between low pressure, high humidity, and increased pain reports. Both studies are real; they simply don't agree.
Disputed origin
Earliest known record: Long-standing oral and folk medical tradition, formally tested by Redelmeier and Tversky in 1996 and again by the University of Manchester's 'Cloudy with a Chance of Pain' study in 2016
This is one of the few beliefs on this site with two genuinely rigorous, opposing formal studies behind it rather than none at all — which makes the honest answer 'the evidence is mixed,' not a confident yes or no in either direction.
The 1996 study that found nothing
Researchers Donald Redelmeier and Amos Tversky ran a genuinely careful test: 18 arthritis patients, 17 of whom already believed their pain tracked the weather, recorded their joint pain levels twice a month over 15 months, while physicians independently measured actual joint tenderness and function. When the researchers compared the patients' own reported pain against the specific weather conditions each patient had named as their personal trigger, they found no statistically significant association at all. Their conclusion pointed to a cognitive pattern called selective matching — people notice and remember the days when pain and bad weather coincide, and don't register, in the same way, the many days when they don't.
The 2016 study that found something
Twenty years later, the University of Manchester's "Cloudy with a Chance of Pain" project took a very different approach: a smartphone app called uMotif tracked pain self-reports from more than 13,000 UK participants over fourteen months, with local weather data pulled automatically via each participant's phone location. That much larger, real-world dataset found a real, if modest, statistical relationship — days with higher humidity, lower barometric pressure, and stronger wind were associated with more reports of high pain, with humidity showing the strongest link and, notably, temperature itself showing no clear association at all.
Why this page won't declare a winner
Both studies were conducted by serious researchers using real data, and they point in different directions — a small, tightly controlled clinical study versus a huge, real-world crowd-sourced one, using different methods and measuring somewhat different things. Rather than picking whichever result flatters the folk belief or debunks it more cleanly, the honest summary is that the scientific question remains genuinely unsettled, which is a rarer and more interesting position for this site to take than a confident verdict either way.
A plausible mechanism, even without a settled verdict
It's worth noting that a physical mechanism is at least plausible even without conclusive proof: changes in barometric pressure could, in principle, affect pressure inside already-inflamed joint tissue, giving the belief a mechanism worth taking seriously rather than dismissing outright, even while the actual evidence for how much this matters in practice stays genuinely divided.
Two real studies, two different answers
This is one of the few beliefs on this site where honesty means refusing to resolve the question — a small controlled study found nothing, a huge crowd-sourced one found something modest, and both are legitimate science.
What Different Cultures Say
American folk tradition treats aching joints as a reasonably reliable personal weather signal, often expressed as an older relative's confident claim to feel rain coming in their knees or hips before any clouds are visible.
British and Irish tradition carries the same belief with similar confidence, often specifically attached to old injuries or old fractures being the most sensitive predictor, a detail that adds a plausible-sounding mechanism (old scar tissue, old healed bone) without changing the underlying uncertain evidence.
Russian and broader Slavic folk medicine carries a comparable belief tying joint and bone pain to approaching weather changes, often bundled with broader traditional health advice about protecting joints from cold and damp more generally.
Frequently Asked Questions
Which study is more reliable, the 1996 one or the 2016 one?+
They have different strengths and weaknesses — the 1996 study was small but tightly controlled with independent physician measurement, while the 2016 study was far larger but relied entirely on self-reported pain and phone-location weather data, so neither one straightforwardly overrides the other.
Did the 2016 study find temperature itself mattered?+
No — despite temperature being the factor many people expect to matter most, the study found humidity, low pressure, and wind showed stronger associations with reported pain than temperature did.
Is there a plausible physical reason weather could affect joint pain?+
Yes, at least in principle — changes in barometric pressure could theoretically affect pressure within already-inflamed joint tissue, giving the belief a scientifically plausible mechanism even without settled proof of how much it actually matters.
Does this belief apply only to arthritis, or to any joint pain?+
Both studies discussed here focused specifically on people with existing joint conditions like arthritis, so the evidence, mixed as it is, speaks most directly to that population rather than to occasional aches in otherwise healthy joints.
