And you thought it was hot now! Scientists predict the average weather across the UK in the year 2080 – so just how warm will it get in YOUR area?
- Researchers reveal the ‘life-threatening risk’ of summer heatwaves in the 2080s
- London will reach 105°F (41°C) at least once in a given week during the summers
- It’ll likely be hotter than the 2003 European heatwave that killed 14,000 in Paris
Britain is in the midst of the first spell of unbearably hot weather for the year, but it could be just a taster of what’s to come in a few decades.
Scientists predict that temperatures across the UK in 2080 will be high enough to trigger ‘wide-scale mortality’, much like the European heatwave of 2003.
In a single summer week in 2080, temperatures will hit 105°F (41°C) in London, while weekly averages will be 82°F (28°C) in large parts of southern England.
This compares to London’s peak summertime temperatures of 87°F (31°C) and southern England’s weekly averages of 68°F (20°C) in the 1970s.
Manchester, meanwhile, will push past 100°F (38°C) at least once a week during a 2080s summer, and Plymouth and Glasgow will likely hit 95°F (35°C) weekly.
The study predicts peak summertime temperatures of 41°C in London, and weekly averages of 28°C in large parts of southern England. This compares to 31°C and 20°C in the 1970s. Image shows daily maximum temperatures in the UK for the 1970s (left) and projections for the 2080s (right)

Last year, the UK set a new temperature record of 104.5°F (40.3°C) – but multiple regions will push past this on a weekly basis by 2080, the predictions show.
Peak summer temperatures in the 2080s
London: 105°F (41°C)
Manchester: 100°F (38°C)
Plymouth: 96°F (36°C)
Glasgow: 95°F (35°C)
Temperatures in the biggest cities (namely London) tend to be hotter than the rest of the UK – and will continue to be so in the 2080s – due to densely-packed buildings and more concrete and tarmac that absorb heat more quickly.
The new study was led by Professor David Coley at the University of Bath, who stresses that it is in the extremes of weather, not the mean climate, where much climate change risk lies.
‘Climate change is normally discussed in terms of seasonal averages, as this is what is meant by the word climate,’ said Professor Coley at Bath’s Department of Architecture and Civil Engineering.
‘I believe this a possible mistake, as few of us naturally grasp how even small differences in climate imply hugely different worlds.’
The team cite the European heatwave of 2003, which killed 14,000 people in Paris alone – showing the dangers of extreme temperatures rather than average temperatures.
In the last 20 years alone there has been a 54 per cent increase in heat-related mortality in people older than 65, with a total of 296,000 deaths in 2018 alone.
‘It’s such heatwaves and cold snaps, and a lack of preparation for them, that will increasingly kill people,’ said Professor Coley.
‘We need to think about climate change in terms of changing weather.’

For their study, Professor Coley and colleagues produced a series of detailed weather projections for 11,326 UK locations at 3-mile-square intervals for the year 2080.

Using weather generator software and a newly developed algorithm, the team built upon Met Office climate predictions to create the projections.
After inputting the climate prediction data into the software, the weather generator produced 3,000 examples of possible weather forecasts for 2080.
By then looking for heatwaves and examining how they changed over time, they discovered that there will be heatwaves of similar form as the 2003 Paris event.
However, these future heatwaves will be ‘with even higher temperatures’, suggesting the likelihood of ‘largescale mortality’.
The authors say climate change has the potential to undermine many of the gains in public health over the past 50 years, which will ‘exacerbate existing inequities’.
Vulnerable populations, such as the elderly or those with pre-existing medical conditions, will be disproportionally affected, according to the experts.
‘Exposure to high temperatures impact individuals via various routes from heat stress and heatstroke to exacerbations of respiratory and cardiovascular disease,’ they write.

What’s more, the UK is badly prepared for temperature increases, not only in terms like buildings and infrastructure, which are not heat-resistant enough.
‘No temperature record exists of the internal conditions within the buildings in which the 14,000 deaths occurred in Paris in 2003,’ the team say.
‘The predicted situation in London is similar to that found in Paris, but with the peak temperature being higher in London and the night-time temperature in London being considerably higher.
‘It would therefore not be unreasonable to conclude that in the future the UK can expect events with moralities of similar number as Paris suffered.’
Weather files containing the extreme weeks for 11,326 locations have been prepared by the academics and made available online, while the study has been published in the journal Building and Environment.
Life-threatening temperatures above 100F will be up to TEN TIMES more common in Britain by the end of the century, study warns
Life-threatening temperatures above 100°F will be up to 10 times more common in Britain by the end of the century, a study found.
Researchers looked at future climate projections to see how global exposure to ‘dangerous environments’ will increase in the coming decades.
By 2100, a ‘dangerous’ temperature of 103°F (39.4°C) will be three to 10 times more common by 2100 in mid-latitude countries such as the UK and the US.
More than half the year ‘will be a challenge to work outside’ in countries along the equator because of scorching weather by 2100, although ‘deadly’ heatwaves could happen every year in the mid-latitude countries too.
