London’s risk from rising temperatures
Open
2117 Londoners have responded

Discussions
The summer of 2022 saw temperatures above 40°C, the highest ever recorded in England. Climate change could bring hotter, drier summers in London, with longer, more intense heatwaves.
City Hall’s Climate Adaptation team wants to hear your experience to help inform London’s first Heat Risk Delivery Plan.
Join the conversation
Thinking back to the heatwave of 2022:
- How did you cope with the heat in London?
- What helped you stay cool at home or while you were out and about?
- What made it better, and what made it worse?
Thinking of this summer:
- What, if anything, are you doing differently to cope with the heat in London?
- What, if anything, does London need to help you cope with the heat?
Please share as much detail as you can. Eleanor and Annette from City Hall’s Climate Adaptation team will be reading your comments and joining in.
About the action plan
The London Heat Risk Delivery Plan will set out the roles and responsibilities our city needs to manage heat risk. The recommendation for this action plan came out of last year’s London Climate Resilience Review.
Between March and September 2025, Londoners and stakeholders are invited to help inform the action plan. Read more on our background page.

Show full commentin 2022 the heat was so high it broke panes of glass and bent window frames out of shape in my home. To cope with the heat, we created a shaded area on the flat's balcony, placed reflective sheets on the windows, and followed the advice re windows closed and open in the day. For the dog we used wet towels on its belly, as that's a good way to cool them off, and lots of showers for ourselves. it was exceedingly uncomfortable all the same, and we have since acquired an air conditioning unit, which helps a little. We avoided direct sunlight for the duration of the heatwave.
Show less of commentI live in a converted victorian house. This was built for a different Britain, and lacks ventilation. While this can be retrofitted it is at significant cost, far higher than can reasonably be met by any householder or landlord, social or no. It is obvious that sponsored retrofitting of climate controlling measures (for heat and cold) and energy efficiency is required.
Outside crops that worked five years ago no longer flourish and new crops begin to thrive. We have noticed in particular that crops used to arid conditions are doing well, but these must also be able to handle intermittent flood. We can attest to grass becoming parched to the extent that it does not recover, and London's trees sacrificing branches to survive heat. We are seeing more deaths among small birds and fledglings.
Water is essential, and it must be put to work. It makes sense to create more water features across London's parks, ensure water is available in those parks, and invest in drinking water.
However doing so would be prohibitive in cost due to water privatisation. As such it is a matter of both common sense and national survival that water supply is nationalised as the need for it is far too great to be in the hands of any private entity. From cooling to crops to public safety, water is national security and its management is a matter of national importance.

Community Member 15 hours agoDozens of questions and not a single one mentions air conditioning, which is the reason I’m cool during this heatwave by the way.

Show full commentBuying an air conditioning unit was the only way we could stay cool. It's not very efficient, and requires us to put a tube out of the window. London should update its development regulations to allow for more air conditioning units to be installed in new builds. In particular, air to air heat pumps which can cool in the summer and heat in the winter. This also helps with out green energy transition

Community Member 20 hours agoI think commenters who are saying not to use AC are naive. There are other things we can do of course, but let's be realistic - they aren't that great. Any solution that relies on human behavioral change is going to be unreliable at best

Community Member 20 hours agoHeat pumps can act as AC in the summer and heating in the winter but existing subsidy for them isn't allowed for heat pumps that provide AC. Changing that seems obvious.

Community Member 20 hours agoI think the modern electric buses have AC but it's completely useless because the windows are always opened letting the heat in
Can we remove the ability to open windows in all spaces that have AC?

Misting stations are of limited effect here... the UK is already a humid country, past a certain point misting only increases the heat index and makes the heat feel worse to living animals.

As well as planting more trees, look at Singapore & Barcelona, how they have invested in public spaces, infrastructure for pedestrian and cyclists whilst planting trees everywhere, the temperature of the cities have dropped multiple degrees.

Show full commentWe need to be supporting our NHS more during heatwaves. I work in a tertiary hospital, and during these times our wards reach 30 degrees consistently. Despite fans for each patient, this is still extremely uncomfortable, and can frequently affect patients clinically too. We then have staff who have no option but to work in these conditions, and any office space for clinical staff is cramped without fans or aircon.

It's just hot weather and it's called summer. Nothing else.

The Seine in Paris is now open for swimming in the summer in Paris which is amazing for cooling off. They also advertise public swimming pool and i believe some of them are free to access in the summer. Improved access to swimming spots is essential I think.
I've also noticed tree-lined streets are noticeably cooler than streets with no trees. Perhaps planting more trees might be an option.

Community Member 1 day agoThe tube gets horrendously hot. The Northern line and Victoria line in particular are at extremely high temperatures. I don’t think it’s safe - they need to prioritise air conditioning on these tube lines ASAP before next summer.

Show full commentLoving in Feltham and dependent on public transport it's not always easy to cope with high temperatures when doing daily activities. Buses need to have better AC units and bus stops should have at least shade or misting units. More than once I felt sick during bus journeys because of how hot it was and how full the bus was. I also witnessed people falling ill and fainting.
The worst is walking out to buy groceries, there's very little natural shade to protect. More trees or at least misting stations would help.
Staying at home isn't easy either. My flat is on the top floor, so I get the rising heat from underneath and the full strength of the exposure to the sun. I found myself spending more time outside the house, jumping from shop to shop chasing the ac. Landlords should be pushed to make adaptations for extreme heat, be that installing black out blinds, window covers, anything.
I travel to Japan a lot and heat is also a problem in Tokyo. Houses are better equipped, with better materials to sustain heat and AC is much more common.
For work commutes and walking outside, the heat is an economy. There are vending machines to purchase cold drinks, convenience stores sell cooling aids such as cooling wipes and sprays, ice cups, regular bottled drinks but frozen, UV blocking parasols. Maybe we could incentivise our local shops to sell some of these during heat waves. And vending machines could unlock to provide free water during days of extreme heat.
I have started to see misting stations near public attractions and parks as well. Green areas are well kept and have facilities such as toilets and vending machines or a little shop, so people use them more often to hide in the shade throughout the day.
Trains, buses and the metro system are equipped with AC.
