Last week brought exceptional temperatures across the UK, prompting the Met Office to issue a Red Extreme Heat Warning across much of England. The heatwave saw parts of the UK experience some of the highest June temperatures ever recorded, with temperatures climbing to beyond 35°C for three consecutive days. This put significant pressure on the emergency services, transport, networks, infrastructure, energy, and water supply across the country.
While the immediate focus was on protecting public health, the prolonged period of extreme heat also exposed the vulnerability of infrastructure that underpins the UK's economy. Roads, railways and public services all experienced disruption as unusually high temperatures affected assets that are traditionally designed to operate in a much cooler climate.
According to BBC News, road surfaces in several areas in the South of England softened under the intense heat, resulting in melting asphalt, emergency repairs, traffic disruption and heightened network maintenance, forcing Local Councils to respond quickly to deteriorating road conditions. There were significant delays as damaged sections of the network were repaired, and rail operators introduced temporary speed restrictions to reduce the risk of heat-related damage to tracks, causing further disruption to passengers and freight services.
These delays have broader economic consequences: delays for commuters affect productivity, while disruptions to freight and logistics networks can negatively impact supply chains and increase operating costs for businesses. Emergency maintenance also places additional pressure on already stretched local authority budgets, particularly as periods of extreme weather are reported to become more frequent.
The latest heatwave continues a broader trend that climate scientists have been monitoring for many years. In a recent blog marking the 50th anniversary of the 1976 heatwave, The Met Office explained that temperatures once considered exceptionally rare are becoming increasingly likely as the climate changes.
Professor Stephen Belcher CBE, Met Office Chief Scientist, said: “The heatwave this week will be a significant weather event, with a Red Extreme Heat warning issued. Human-induced climate change has made events like this more likely and more intense. To see temperatures like this in the UK in June is sobering. Events like this bring home the implications of climate change, with very high temperatures and humidity bringing significant health implications from heat stress, as well as impacts to a range of sectors such as transport, energy and water supply.”
The latest projections by The Met Office suggest that, under high-emissions scenarios, parts of the UK could experience temperatures reaching 45°C by the 2050s. Last week's event, which saw the UK record its hottest June day, demonstrates how these projections are becoming increasingly relevant to infrastructure planning today.
As extreme weather events become a more familiar feature of the UK's climate, the ability to observe and measure change over time will play an increasingly important role in helping organisations make evidence-based decisions.
For organisations responsible for managing roads and other critical assets, understanding how infrastructure changes over time is increasingly important. Repeated exposure to extreme weather can accelerate wear, highlight existing weaknesses and increase maintenance requirements. Having access to accurate, up-to-date information enables better planning, more informed investment decisions and improved resilience.
At Terra Visus, we provide high-resolution street-level imagery and LiDAR datasets that provide an important foundation for this work. By capturing the condition of roads, highways and surrounding infrastructure over time, historical datasets allow organisations to track change, identify deterioration and build a clearer picture of how environmental factors affect the built environment, providing a valuable record of how infrastructure evolves and supporting better planning, asset management and most importantly - long-term resilience for the future.
