Researchers at the University of Manchester tracked over 2,600 people with chronic pain conditions across the UK for around six months, using a smartphone app that logged daily symptoms alongside local weather data (Source: University of Manchester, 2026). Humid days showed the strongest link to pain, with low atmospheric pressure and higher wind speeds also associated with more painful days. Temperature on its own showed no clear link when averaged across the whole group. So if an old injury or achy joint feels worse as it gets colder, the weather is probably still involved, just not quite in the way you'd expect.
Who this is for
You've got an old injury, a joint that's been through something before, or just a spot that seems to flare up every winter, and you want to know whether that's actually a real pattern or something you're imagining. This is for you, whether you're looking for reassurance, something practical to try, or a sense of when it's worth getting checked.
What the research actually found
The study, called Cloudy with a Chance of Pain, recruited over 13,000 people from every UK postcode area, with 2,658 providing daily data for around six months through 2016 (Source: University of Manchester, 2026). Rather than relying on memory or general impressions, the app pulled local weather data from each participant's phone and matched it against what they reported feeling that day.
Humidity had the strongest association with pain, humid days were the most likely to be painful, dry days the least. Low atmospheric pressure and higher wind speeds were also linked to more painful days, though less strongly than humidity. Temperature by itself showed no clear association across the group as a whole, though the researchers noted that cold, damp and windy conditions together could still add up to more pain. Rainfall on its own wasn't linked to pain at all.
Lead researcher Professor Will Dixon pointed out that around three-quarters of people with arthritis already believe weather affects their symptoms, an idea that goes back as far as Hippocrates, and this study was one of the first to test it directly using real daily data rather than relying on recollection (Source: University of Manchester, 2026).
Why this still lines up with what you might be noticing
If your knee or your back tends to feel worse in winter, this research doesn't contradict that, it just points to a more specific cause than "cold" on its own. Winter in the UK tends to bring damp, windy, low-pressure days bundled together, exactly the combination the study found most linked to pain. There's also a simpler, practical factor worth naming: people generally move less when it's cold and dark outside, and reduced movement on its own can make joints and old injuries feel stiffer and more uncomfortable.
What tends to help, and when to get it checked
Staying as active as you comfortably can, even gently, tends to help more than resting completely, since movement is what keeps joints from stiffening up further. Layering up before you go out, warming up properly before exercise, and not pushing through sudden or sharp pain are all sensible, ordinary precautions rather than anything specific to this research.
If pain is new, getting worse rather than following its usual seasonal pattern, or is affecting how you move day to day, that's worth raising with a physiotherapist or a GP rather than assuming it's just "the weather." A seasonal ache you recognise is different from a new or worsening problem, and it's worth being honest with yourself about which one you're actually dealing with.
A University of Manchester study tracking over 2,600 people across the UK found humidity, low pressure and wind speed were more strongly linked to pain than temperature on its own, though cold, damp and windy conditions together could still add up to more pain (Source: University of Manchester, 2026). Around three-quarters of people with arthritis already believe weather affects their pain, and this was one of the first studies to test that using daily real-world data rather than memory. Staying gently active and dressing appropriately for the cold are sensible everyday steps. New, worsening, or unusually severe pain is worth raising with a physiotherapist or GP rather than putting down to the season.
Questions people often ask
Not on its own, according to a large UK smartphone study. Humidity, low atmospheric pressure and wind speed showed a stronger link to pain than temperature alone, though cold combined with damp and windy conditions could still add up to more pain (Source: University of Manchester, 2026).
Winter weather in the UK often combines the conditions most linked to pain in the research, humidity, wind and low pressure, and people also tend to move less when it's cold and dark, which can make joints feel stiffer.
Staying gently active rather than resting completely, dressing warmly, and warming up properly before exercise are sensible, ordinary steps. None of these are specific treatments, just practical ways to manage a seasonal pattern.
If pain is new, getting worse rather than following its usual seasonal rhythm, or is starting to affect how you move day to day, it's worth speaking to a physiotherapist or GP rather than assuming it's just the weather.
This research included people with a range of chronic pain conditions, including arthritis, so the same weather pattern applies broadly. If you don't have a diagnosed condition and pain is new, that's still worth getting checked rather than assuming it's seasonal.
