Sussex has entered a state of prolonged dry weather, joining Hampshire and the Isle of Wight as pressure builds across the South East. The Environment Agency says the shift reflects a familiar mix of hot weather, limited rainfall and rising demand for water. Hampshire and the Isle of Wight were moved into this category 11 days earlier, and Sussex is now feeling the same strain. South East Water has said temporary use bans are due to come into effect on Saturday 25 July in Hampshire, Sussex, Surrey and Berkshire, adding to restrictions already affecting Kent. For residents, that turns a dry summer into something more immediate: a reminder that water stress is no longer abstract, and that daily habits now matter.

A prolonged dry weather declaration is not the same as a full drought, but it does mark a tighter phase of management. The Environment Agency says it is ready to consider requests around water use and respond to environmental incidents linked to heat and reduced water availability. Richard O’Callaghan, the agency’s environment planning and engagement manager, said the pattern now stretches from Cornwall to Sussex and into other parts of England. His message was straightforward: everything depends on water, and higher use by people leaves less available for rivers, wildlife and the wider environment.

One of the clearest local warning signs is the Cuckmere River. South East Water says levels are now too low for abstraction, affecting Arlington reservoir in Sussex. In plain terms, there is less water that can be taken from the river without adding to ecological pressure. That matters because rivers are not simply pipes feeding reservoirs. When flows fall, fish habitats shrink, water temperatures rise and the margin for safe extraction narrows. Sussex’s dry weather status is therefore not only about supply for homes; it is also about how much strain local waterways can take.

Environment Agency rainfall figures for the Solent and South Downs show why a wetter June has not solved the problem. January was exceptionally wet at 186mm, or 193 per cent of the long-term average, and February reached 143mm, or 212 per cent. The pattern then changed sharply, with March dropping to 33mm, April to just 9.4mm and May to 32mm. June improved to 75mm, or 136 per cent of average, but that rebound came after three notably dry months. This is the part of drought management that often gets missed. One wetter month can freshen the surface, but it does not fully repair the deficit left in soils, streams and stored water. The data points to a stop-start year in which heavy rain early on gave way to a much drier spring, leaving catchments exposed when summer heat arrived.

The response is now being handled at both regional and national level. The National Drought Group, which includes the Met Office, government departments, regulators, water companies, the National Farmers’ Union, the Canal & River Trust, anglers and conservation specialists, is monitoring how conditions develop. If the situation worsens, the decision route is already set out. The Environment Agency will rule on drought permit requests, while Defra and the Secretary of State will decide on any drought orders using technical advice from the agency. That process may sound procedural, but it shapes how water is shared between homes, farming, business and the natural environment when supplies tighten.

For Eco Current readers, the most useful part of this story is also the most practical. The Environment Agency is backing the Let’s Save Water campaign, and its advice is focused on actions that can cut demand quickly without drama. Low-flow showerheads, using washing machines only with a proper load and skipping the pre-rinse on dishes are all simple moves with real value when pressure is building. None of those steps replaces the need for long-term investment in water security, but they do buy time for rivers and reservoirs when every reduction counts. In a densely populated and water-stressed region, small cuts made across thousands of homes add up fast.

Sussex joining prolonged dry weather should be read as an early warning rather than a final stage. The immediate task is to steady demand, protect vulnerable rivers and make sure water companies stick closely to their drought plans. The wider lesson is that hotter periods, uneven rainfall and rising demand are no longer rare planning problems for the South East. A more resilient response means acting on two tracks at once: using less water now, while also pushing harder on leakage, storage, catchment health and public honesty about what summer water use costs. There is still room for steady, sensible action. But the signal from Sussex is clear: managing drought starts well before taps run dry.
