Since 2025, University of Manchester researchers modelled 2,300 urban canal sections across Great Britain and Ireland. Now, the study shows canals can lower nearby temperatures by as much as 2.3C during heatwaves

Urban canals cooling: Urban canals provide a notable cooling effect on surrounding areas, particularly during heatwaves. This natural cooling can reduce daytime temperatures by up to 2.3 degrees Celsius. Millions of people living near these waterways could benefit from this effect. The research suggests canals play a role in urban adaptation to climate change.
