Sussex Experiences Extended Dry Spell Alongside Hampshire and Isle of Wight

Parts of Hampshire and the Isle of Wight have entered a period of prolonged dry weather, commencing 11 days earlier than previously anticipated, due to increasing environmental pressures. This trend of elevated temperatures, insufficient rainfall, and heightened water demand is now also being felt in Sussex.

Water Use Restrictions Implemented Across the Region

South East Water has announced that temporary usage restrictions will be enforced in Hampshire, Sussex, Surrey, and Berkshire, effective from Saturday, 25 July, thereby extending similar measures already in place in Kent. The water utility has highlighted that the Cuckmere River’s water level is currently too low for abstraction, which is impacting the Arlington reservoir in Sussex.

The Environment Agency has indicated that the current state of prolonged dry weather allows it to consider requests regarding water usage and to respond to any environmental incidents stemming from the ongoing heatwave and its effects on water resources.

Richard O’Callaghan, the Environment Planning and Engagement Manager at the Environment Agency, remarked on the widespread impact of this dry weather, stating, “Prolonged dry weather is affecting a lot of England, now reaching from Cornwall to Sussex and beyond. Everything relies on water, and we must use it wisely. The more water we consume, the less will be available for the environment.” He assured that the agency is prepared to balance the demands for water with environmental needs and ensure that water companies adhere to their drought management plans.

Impact on Agriculture and Local Ecosystems

While June recorded above-average rainfall levels across the Solent and South Downs regions, it fell short of compensating for the three preceding months of dryness. The National Drought Group, which comprises representatives from the Met Office, government bodies, regulators, water companies, the National Farmers’ Union, the Canal & River Trust, angling organisations, and conservationists, is actively monitoring the situation.

As the regulatory body, the Environment Agency will evaluate any requests for drought permits. However, the final decisions on drought orders will rest with the Department for Environment, Food and Rural Affairs (Defra) and the Secretary of State, with the Environment Agency providing essential technical advice to assess the needs of both the populace and the environment.

Community Initiatives for Water Conservation

The Environment Agency is also championing the Water Efficiency Campaign, which was launched this month under the banner “Let’s Save Water.” This initiative, underpinned by scientific research and evidence, aims to promote water conservation practices among the public.

Individuals can contribute to water-saving efforts through simple measures such as installing low-flow showerheads, operating washing machines at full capacity, and avoiding the pre-rinsing of dishes. These small changes can collectively make a significant impact in alleviating the pressures on local water supplies.

Long-Term Rainfall Trends in the Region

In terms of the monthly rainfall figures for the Environment Agency’s Solent and South Downs operational area, the long-term averages for 2026 are as follows:

• January: 186mm (193%)
• February: 143mm (212%)
• March: 33mm (58%)
• April: 9.4mm (17%)
• May: 32mm (63%)
• June: 75mm (136%)
