Wildfires began to break out across England. The two largest fires broke out at Saddleworth Moor on 25 June, and at Winter Hill on 28 June, the former being England's largest in living memory. As of September 2018, arrests have been made on the charge of arson, yet the cause of these fires is undetermined. However, the factor that allowed the fires to establish was the persistently hot and breezy weather conditions. This dried out vegetation and the underlying peat, allowing it to easily burn.
