The British weather has always been a national preoccupation, but the conversations are changing. The question is no longer just whether it will rain at the weekend — it is whether the flooding that devastated parts of Yorkshire and the Somerset Levels will become an annual event rather than a once-in-a-generation occurrence.
What the Data Shows
The ten warmest years in the UK's recorded weather history have all occurred since 2003. The five years 2019–2023 are the warmest five-year period on record. Rainfall patterns are shifting: average summer rainfall in southern England is declining, while extreme rainfall events — heavy downpours that overwhelm drainage systems — are becoming more frequent nationally.
Flooding: A Growing Emergency
The number of English homes at significant risk of flooding has risen to 5.2 million, up from 4.4 million a decade ago. The Environment Agency's flood defence programme protects more homes than before, but so-called "residual risk" — the chance of flooding even behind defences — is increasing as climate extremes intensify.
Agriculture
British farming is being reshaped by changing weather patterns. Longer growing seasons benefit some crops; drought stress is increasingly affecting others. The potato harvest in southern England has been affected by summer drought in three of the last five years.
What Households Can Do
The government's flood risk map (check-long-term-flood-risk.service.gov.uk) allows anyone to check whether their property is at risk. Flood resilience measures — air brick covers, flood doors, resilient flooring materials — can significantly reduce damage when flooding does occur.
