London is on track for its longest rainless period since 2018. Forecasts show no rain until late next week. The city is experiencing high temperatures and increased wildfire risk.
London is heading for its most prolonged stretch without rainfall in eight years, as persistent heat and drought continue to grip the British capital. According to data from the Met Office and the National Fire Chiefs Council (NFCC), the city has not seen measurable precipitation since July 5, and forecasts indicate that rain is unlikely to return before July 24. This would mark the longest dry period for London since 2018, with only the possibility of light showers in some areas late next week.
The ongoing dry spell has coincided with a series of heatwaves that have swept across the United Kingdom since May. The most recent surge in temperatures peaked on July 9, with thermometers in London reaching up to 34°C. These extreme conditions have not only intensified the drought but have also contributed to several wildfires, causing significant disruptions to transport and requiring emergency services to intervene.
Met Office records show that central and southeastern England experienced 14 consecutive days without rain between July 2 and July 15. This is the longest such streak in the southeast since 1997 and in central England since 1996. Data for July 16 had not yet been released, leaving open the possibility that the record could be extended further.
The lack of rainfall has left vegetation parched and heightened the risk of wildfires. Between January 1 and July 16, England and Wales reported 499 wildfires—fewer than the 748 incidents recorded during the same period last year, but still well above the average for recent years. The NFCC has urged the public to exercise caution, avoid disposable barbecues, properly extinguish cigarette butts, and refrain from leaving litter in natural areas. Officials emphasize that most wildfires are preventable and warn that the elevated risk will persist as long as the hot, dry conditions continue.
While temperatures are expected to moderate slightly over the coming weekend, with highs near 24°C, the following week is forecast to remain warmer than usual for this time of year, with daily maximums between 25°C and 26°C. The extended dry weather in London mirrors broader patterns seen across Europe, where several countries have faced record-breaking heat and drought. For example, Spain is also bracing for another severe heatwave, with authorities warning of temperatures potentially exceeding 45°C, as detailed in this recent report: Meteorologists warn Spain of new extreme heatwave risk.
Prolonged periods without rain can have significant consequences for urban infrastructure, agriculture, and public health. In London, the combination of high temperatures and dry conditions has already led to increased pressure on emergency services and raised concerns about water supply and fire safety. The Met Office and NFCC continue to monitor the situation closely, advising residents to stay informed and take necessary precautions as the city awaits the return of rain.
