Temperatures are set to reach an unprecedented 35C in parts of England on Monday, potentially breaking the May temperature record by a significant margin of 2.2C. This follows a record-breaking May overnight temperature of 19.4C, with London narrowly missing a “tropical night.” Many areas are officially experiencing heatwave conditions, a trend amplified by the climate crisis which is making such events more intense and frequent, with hot temperatures expected to persist and potentially worsen later in the summer.

Parts of England are bracing for an unprecedented May heatwave, with temperatures expected to soar to a scorching 35 degrees Celsius (95 degrees Fahrenheit) on Monday. This marks a significant departure from typical May conditions, with the current record for the hottest May day in the UK standing at 32.8 degrees Celsius. The fact that records are usually broken by mere tenths of a degree makes this extreme surge in temperature particularly noteworthy and, frankly, alarming for this time of year. To put it into perspective, just last week, many regions experienced temperatures around a considerably cooler 15 degrees Celsius. This dramatic shift, with some areas seeing a 10 to 15-degree Celsius jump in less than 48 hours, highlights the volatile nature of the current weather patterns.
The severity of this heatwave is amplified by the fact that the UK is simply not built for such extreme temperatures. Unlike countries accustomed to consistent heat, British infrastructure and housing are designed to retain warmth, making them ill-suited to dealing with intense heat. Many homes are constructed with brick and feature large windows that face the sun, often lacking eaves for shade. This design means that even with windows and curtains closed, interiors can become hotter than the outside environment. The problem is compounded by the slow cooling of brick walls, which absorb heat throughout the day and retain it through the short “night” periods, failing to cool down sufficiently before the sun begins to heat them again. Furthermore, the concept of air conditioning, a common solution in hotter climates, is largely absent in UK homes. Estimates suggest only about 10% of homes are equipped with air conditioning, a figure that has only seen a recent, modest increase. For many, the expense of purchasing and running air conditioning units is prohibitive, especially given the high energy prices in the UK, and the limited space available in many smaller homes presents another practical barrier.
The sheer duration of daylight during this period further intensifies the heat. In some parts of the UK, the sun rises as early as 4:30 AM and doesn’t set until after 9:30 PM, meaning over 17 hours of continuous solar exposure. This prolonged sun exposure, combined with the way homes are built to retain heat, creates an environment where internal temperatures can become unbearable, leading to issues like heat exhaustion, which some individuals have already experienced. The suddenness of this heat is also a significant concern for those responsible for livestock and horses. Animals require time, often weeks, to acclimatize to substantial temperature changes, and the rapid 10-15 degree increase presents a serious challenge, potentially leading to heatstroke and other health complications.
Looking ahead, the situation is unlikely to improve and may even worsen. Experts predict that more heatwaves are probable throughout the summer as a “super El Niño” phenomenon is expected to emerge. This climatic event is known for supercharging weather patterns, leading to more extreme events, including hotter heatwaves. While the full impact of this phenomenon is anticipated to peak in 2027, potentially breaking global heat records, its influence is expected to begin building this summer, suggesting a concerning trend for the UK’s climate. This long-term outlook raises serious questions about the country’s preparedness for sustained periods of extreme heat.
The impact of such high temperatures extends beyond personal comfort and animal welfare, posing a significant threat to agriculture. Temperatures exceeding 35 degrees Celsius can be problematic for the growth of staple crops like corn and wheat. This could have far-reaching consequences for food security, especially when considered alongside existing challenges like fertiliser shortages due to global conflicts, which are already beginning to affect harvests worldwide. The reliance on agriculture means that sustained heatwaves could lead to crop failures and increased food prices.
This escalating climate situation is not entirely surprising, with scientists having warned about such changes for decades. However, a lack of decisive action has meant that societies have largely continued on a path of inaction. The current heatwave, while alarming, is part of a discernible and ominous pattern of increasingly severe weather events. Recent years have seen a succession of record-breaking heat events, including the hottest summer on record in 2025, the hottest May ever in 2024, and extreme heat warnings issued by the Met Office in 2021, followed by a heatwave exceeding 40 degrees Celsius in 2022. This trend suggests that “unprecedented” may soon become a recurring descriptor for heatwaves, rather than an indicator of true novelty.
In response to these rising temperatures, there are practical measures individuals can take to mitigate heat within their homes. These include applying reflective coatings to windows, installing external shutters or shade structures, and increasing the number of trees in urban areas to provide natural cooling. In gardens, prioritizing green spaces over paved surfaces and growing vines on south-facing walls can help. At a structural level, improvements like better loft insulation and using higher albedo (more reflective) roof tiles can make a difference. While some of these solutions require significant investment, they offer a pathway towards greater resilience against extreme heat. The broader societal response, however, needs to move beyond individual efforts and address the systemic causes of climate change, even as the immediate focus shifts to adaptation and coping with the heat that is already here.
