The Environment Agency declared official drought conditions across seven regions covering large areas of central, eastern, and southern England on July 29, 2026.
Persistent dry weather has severely depleted water reserves.
Official records show July brought just 7% of expected rainfall across England, with levels plunging to 1% in southern regions.
River flows dropped significantly at 84% of monitored sites, while nationwide reservoir storage fell to 75.3%.
"The hot and dry weather means we are currently using water faster than nature can replenish it," said Helen Wakeham, director of water at the Environment Agency and chair of the National Drought Group.
Widespread water use restrictions now affect nearly 40% of England's population.
Temporary use bans were expanded by major utility providers, including Thames Water and South East Water, while the Environment Agency manages growing environmental incidents and wildfire risks.
Agricultural Impacts Severe
Agricultural impacts remain severe across southern regions, where early cereal harvesting, livestock feed shortages, and crop failures are worsening.
Agronomist advice indicates UK crop yields have dropped by an average of 25% this season.
"We think the River Parrett was lower in 1976, but I would say this is the worst drought since," said Duncan Palmer, a farmer from Bower Hinton in Somerset.
Drought conditions followed an extended dry spell through mid-July, during which weekly rainfall stayed under 1 millimeter across the country, driving soil moisture deficits to record highs in multiple regions.
"This year, it's not good at all - not for the crops, not for the livestock," Palmer said.
In Somerset, Met Office data indicates this summer is tracking as the fourth driest since records began, trailing only the historic dry spells of 1995, 1976, and prior benchmarks.
Farmers report substantial heat damage to field vegetables and brassica crops planted earlier in the month.
"We do seem to have these long dry spells now, we used to say in this country that if you don't like the weather then wait a minute but that doesn't apply anymore," Palmer said.
Irrigation infrastructure is under severe pressure as farm reservoirs run dry and 1,353 abstraction licence restrictions take effect across river catchments.
"You just have to work with it and not let it get to you," Palmer added.
Extreme heat accelerated crop losses before growers could supply adequate irrigation water to vulnerable fields.
"It's not just the lack of rain it's the temperature - some crops died from the heat before we got water onto them," said Richard Plowright, an organic farmer at Over Stowey in the Quantock Hills.
Multiple growers reported the total loss of parsnip and celeriac crops, alongside stunted development in early brassica varieties.
"We're desperate for rain and we hope there's enough time, light and temperature left in the year to bring these plants on, so we can all have sprouts for Christmas," Plowright said.
Agricultural advisers warn that compounding global factors could influence local food pricing structures.
"We are looking at different planting systems in the future which will protect the soil from high temperatures," Plowright said.
The combination of climate patterns and international supply strains presents rare market conditions for British agriculture.
"This is the first year I've known where things not just here in the UK but elsewhere in the world, [with] geopolitical issues or weather patterns like El Nino, where we could actually see a big impact on prices locally," said Sam Pociecha, an agronomist who advises farmers.
Drought conditions were previously declared in North Wales and the Upper Severn basin, while parts of eastern Scotland remain monitored under significant water scarcity classifications.
"They are amazingly resilient," Pociecha said.
The National Drought Group continues to coordinate regional responses and monthly monitoring across affected catchments.
