Answer:
The 2019 United Kingdom wildfires were a series of wildfires which began on 26 February 2019 and ended on 18 May 2019.[2] The series of wildfires was considered unusual due to the fact that they took place early in the year. Areas affected by the wildfires in 2019 included those that had already been burnt by wildfires during the summer of 2018. The fires have created many air pollution problems for the UK.[3] The causes of most of the fires have been attributed to much higher than average temperatures and drought conditions that have prevailed since the spring of 2018.[4][5] There were 137 wildfires larger than 25 hectares (250,000 m2) recorded in the United Kingdom in 2019.[6] This beats the previous record of 79 from 2018.[7]
