London is experiencing an intense heatwave, with temperatures reaching 36 degrees Celsius, marking the highest June reading in five decades. The unusual weather has prompted a series of disruptions across the city and raised concerns about public safety.

Local authorities have issued warnings advising residents to avoid outdoor activities during peak hours between 11 a.m. and 3 p.m., when the temperature is expected to reach its maximum. Schools have been closed, and signs in London Underground stations recommend that commuters carry water to stay hydrated. Many Londoners have resorted to using handheld fans to cope with the heat while navigating public transportation and outdoor spaces.

In a rare public display of the heat’s impact, King Charles was seen having an aide hold a fan to help him stay cool. London’s Mayor, Sir Sadiq Khan, urged workers to stay home if possible to reduce travel during this period of extreme weather.

The heatwave has significantly affected transportation and tourism. Thousands of rail services were either canceled or delayed due to concerns about the high temperatures causing damage to the tracks, which could potentially lead to derailments. Several prominent tourist attractions, including Tower Bridge, the Royal Observatory, and the Victoria & Albert Museum, temporarily closed to protect visitors and staff, disappointing many tourists—including a number of Australians accustomed to warmer climates.

Public swimming facilities, particularly outdoor lidos, have seen unusually high demand, with most requiring advance bookings due to capacity limits. The heat has also impacted local businesses; for instance, the popular bakery chain Greggs closed approximately a dozen outlets for two days, citing the need to ensure the safety of customers and employees amid the record-breaking temperatures.

Despite the heat, many London homes lack air conditioning, a common feature in countries with hotter climates, leaving residents ill-prepared for sustained high temperatures. The situation has sparked widespread commentary on the country’s vulnerability to extreme heat events, with climate change discussions gaining renewed attention.
