Sussex prolonged dry weather status and hosepipe ban

When you hear the phrase "prolonged dry weather", it can sound like a vague forecast. In fact, it is a formal step in England’s drought system. On 21 July 2026, the Environment Agency said Sussex had moved into that category, joining Hampshire and the Isle of Wight after similar action there on 10 July. South East Water also said temporary use bans, often called hosepipe bans, would begin in Hampshire, Sussex, Surrey and Berkshire on Saturday 25 July 2026, alongside restrictions already in Kent. (gov.uk) If you live in the South East, the important point is this: the story is not only about a run of hot days. According to the Environment Agency, river levels, reservoir pressure and household demand are all moving in the wrong direction at once. The agency said the Cuckmere River was too low for abstraction, which in turn was affecting Arlington reservoir in Sussex. (gov.uk)

Here is the distinction that matters. Prolonged dry weather is the stage before an official drought declaration. It does not mean taps are about to stop running, but it does mean regulators are preparing for extra pressure, watching environmental damage more closely and getting ready to judge requests about water use. In its 21 July 2026 update, the National Drought Group said no areas were yet officially in drought, even though eight areas of England were already in prolonged dry weather. (gov.uk) **What this means:** officials are trying to protect two things at once. They need enough water for homes, farms and businesses, but they also need enough left in rivers and wetlands for wildlife and fragile habitats. Richard O’Callaghan of the Environment Agency put it plainly: "the more water we use, the less there is available for the environment." (gov.uk)

One of the trickiest parts of this story is that one wet month does not cancel out several dry ones. In the Environment Agency’s Solent and South Downs area, January and February 2026 were very wet at 186mm and 143mm, or 193% and 212% of the long-term average. Then the pattern flipped: March fell to 33mm, or 58% of average, April dropped to just 9.4mm, or 17%, and May reached 32mm, or 63%. June recovered to 75mm, or 136%, but the agency said that still did not make up for the earlier shortfall. (gov.uk) That helps explain why a place can look rainy for a few weeks and still face water stress. Rivers, soils and underground water stores respond over time, not instantly. So when spring has already been dry and demand climbs during hot weather, a wetter June can ease pressure without fully repairing the wider system. That is an inference from the rainfall pattern the Environment Agency published, and it fits the agency’s decision to extend prolonged dry weather status to Sussex. (gov.uk)

The environmental damage can be easy to miss unless you know where to look. In its wider 21 July briefing, the National Drought Group said the third heatwave of 2026 had dried out ponds and wetlands, left some rivers dry in places and forced fish rescues as oxygen levels dropped in shrinking waterways. It also warned that farm harvests had started early and cereal yields were expected to be lower than usual. (gov.uk) This is why the line "Everything relies on water" matters. Water policy is not only about whether your shower still works. It is also about chalk streams, bird breeding, food production, river life and the health of the wider environment. When regulators talk about balancing human need with environmental need, this is what they are talking about. (gov.uk)

The decision-making chain can sound bureaucratic, so it helps to separate who does what. Water companies decide whether to bring in temporary use bans. The Environment Agency, as regulator, decides drought permit requests. If the situation worsens and a drought order is sought, Defra and the Secretary of State make that decision, using technical advice from the Environment Agency on the needs of both people and the environment. (gov.uk) Behind that, the National Drought Group acts as a co-ordination point. The Environment Agency says it brings together the Met Office, government, regulators, water companies, the National Farmers’ Union, Canal & River Trust, anglers and conservation experts. That matters because drought is not one single problem; it is weather, infrastructure, farming, ecosystems and public behaviour all at the same time. (gov.uk)

This is where your daily habits stop being a side issue and become part of the story. The Environment Agency-backed Let’s Save Water campaign points to practical changes that are simple rather than dramatic: fitting low-flow showerheads, running washing machines only with the recommended load and skipping the pre-rinse before dishes go into the sink or dishwasher. (gov.uk) The focus on hosepipes is not random. The National Drought Group said a hosepipe can use around 1,000 litres in an hour, which is more than a family of four typically uses in a full day, and that demand for water had risen by as much as 30% on the hottest days. **What this means:** small choices made by lots of households at once can take real pressure off the system during a heatwave. (gov.uk)

Put together, these updates tell a clear story about a fast-changing summer. Hampshire and the Isle of Wight moved into prolonged dry weather on 10 July 2026. Sussex followed on 21 July 2026. On the same date, the National Drought Group said prolonged dry weather status was already in place across eight areas of England, stretching well beyond the South East. (gov.uk) If you want to know what happens next, watch three things. First, whether late July and early August bring enough rain to lift river and reservoir levels in a meaningful way. Second, whether more water companies tighten restrictions. Third, whether any area moves from prolonged dry weather into official drought. The Met Office told the National Drought Group that some rain was possible into early August, but that southern England was still likely to stay mostly dry for the next few weeks. (gov.uk)
