If you still think the UK is a perpetually rainy island where water shortages are a myth, October 2026 just proved you wrong. A severe drought has officially been declared across parts of southern England, hitting regions in Cornwall, Devon, Dorset, Somerset, East Sussex, and West Sussex. Reservoirs are dropping to alarming lows. Public supplies are under immense pressure.
Met Office data paints a brutal picture. Weather stations across these affected counties recorded nearly 40% less rain between April and September compared to a typical year. The average total hit 232mm, officially beating the previous record low of 239mm set back in 1976. That makes this the driest April-to-September period in at least a century.
Let that sink in. We are dealing with weather extremes not seen for decades.
Where Did All the Water Go?
The numbers behind this drought are staggering. Dorset weather stations received about half their normal rainfall during that crucial six-month stretch. Things were even worse during a brutal two-month dry spell from June 15 to August 15.
Take the Hurn weather station near Bournemouth Airport. It saw a pathetic 1.4mm of rain in total during those two months—just 1% of its typical 100mm summer average. Stations in Bognor Regis and Thorney Island in West Sussex suffered a similar fate, pulling in less than 2% of their normal mid-summer rainfall.
When you combine those kinds of evaporation rates with relentless summer heatwaves, the ground simply bakes solid. Rivers drop, soil cracks, and reservoirs empty out. For instance, the Ardingly reservoir serving roughly 95,000 properties dropped to a chilling 19% capacity. In the South West, smaller reservoirs like Drift and Stithians in Cornwall and Tottiford in Devon are sitting at critical thresholds.
The Friction Between Public Supply and Business Use
When a severe drought hits, the bureaucratic gears start grinding. Environment Agency boss Philip Duffy pointed out that water companies must activate their emergency drought plans immediately. They can't hide behind the weather.
Yet, friction is already brewing at the government level. Environment Secretary Dame Angela Eagle has faced heavy requests from water companies to extend strict prohibitions to commercial users, like golf clubs, private schools, and commercial car washes. While South East Water and South West Water already enforce hosepipe bans for everyday citizens, broad non-essential business restrictions have hit delays.
Water Minister Emma Hardy recently instructed regulators to prioritize public drinking water where trade-offs between environmental rules and consumer taps become unavoidable. But nature is paying the price. Rivers are running low, aquatic life is suffocating, and ecosystems across the south will take years to bounce back.
What This Means for You
If you live in the affected counties, you're likely already tired of hearing about hosepipe bans. But the reality is that waiting for a sudden downpour won't fix structural water stress. Recovery depends entirely on two things: actual rainfall and how much water households choose to burn through day-to-day.
Governments are talking about long-term fixes—like a £65m package for drought-hit farmers and plans to build nine new reservoirs by 2050. That's fine for the history books, but it doesn't help your garden or local reservoir today.
Stop wasting water out of habit. Fix leaking taps, ditch the garden hose for a watering can, and pay attention to local utility alerts. The dry spell is rewriting our weather baselines, and adaptation isn't optional anymore.
