Wales Declares Drought in North Wales and Upper Severn Amid Record Heat

Core Event
On July 23 Natural Resources Wales (NRW) declared drought in North Wales and the Upper Severn, covering North Gwynedd, Ynys Môn, South Gwynedd, the Dee catchment, Clwyd and the Upper Severn. The agency cited exceptionally low river flows, falling groundwater levels and heightened wildfire risk.
Background & Context
The declaration follows three heatwaves and a dry spell that began in April. BBC reported Wales received only about 5 % of the average July rainfall, while the Guardian and Independent noted the catchments have received < 2 % of expected rainfall. On July 16 NRW moved North Wales from “normal” to “prolonged dry weather,” the stage preceding drought.
Data & Statistics
- Rainfall: < 2 % of expected monthly total in the drought-declared areas (NRW).
- River flows: Clwyd, Alwen, Alyn, Clywedog, Dyfi, Conwy and the Wye have recorded new monthly minima or are approaching record lows.
- Water temperature: The Wye and Usk have reached 28 °C.
- Groundwater: Continuous decline across the affected catchments.
- Agriculture: Early ripening of arable crops and projected lower yields; livestock under “excessive pressure.”
- Wildfires: Major blazes at Harlech (origin July 12), the Rhinogydd mountains, and a 5 km fire near Blaenavon covering roughly 200 ha.
- Water use controls: Welsh Water imposed a hose-pipe ban on 33 000 properties in west Wales.
Impact
Wildlife and Water Quality
Low flows and high temperatures have degraded water quality, killing fish and threatening aquatic species.
Farming
Livestock farmers report “excessive pressure on livestock” and need for additional shade and water. Arable growers face early harvesting and anticipate reduced cereal yields.
Wildfires
Dry vegetation has fueled a surge in wildfires, prompting the Welsh Government to activate crisis-management arrangements and seek aerial support. Smoke from the Blaenavon fire has travelled over 30 miles, affecting air quality in Cardiff and surrounding towns.
Official Statements & Responses
A Welsh Water spokesperson clarified that the drought classification differs from the company’s “temporary use ban,” which is driven by local drinking-water demand and reservoir capacity. The Welsh Government confirmed deployment of a specialist firefighting helicopter to the Rhinogydd area and warned conditions could worsen without rain.
On-the-Ground Reports
- “We’ve had really dry weather but also it’s been really hot – and those things combined if you’re a livestock farmer means excessive pressure on livestock,” said Abi Reader, president of NFU Cymru.
- North Wales Fire and Rescue Service reported a “high volume of calls” relating to a grass fire on Bangor Mountain, urging the public to avoid the area.
Conflicting Reports & Gaps
BBC cites 5 % of average July rainfall, whereas the Guardian and Independent cite < 2 % of expected monthly rainfall. No source provides definitive data on the drought’s impact on household drinking-water supplies.

- “The recent wildfires across north Wales and south-east Wales are one of the clearest and most visible signs of how dry our landscapes have become.” — Rhian Thomas
- “And then there are also little things that can be done, such as putting some water out in the garden for mammals and birds.” — Gail Davies-Walsh, chief executive of Afonydd Cymru
What’s Next
NRW warns that continued dry weather could push additional catchments into drought status. Forecasts suggest a chance of rain later in the week, but officials stress that any showers are unlikely to “top up water supplies” sufficiently to reverse the stresses. Monitoring of river flows, groundwater and wildfire activity will continue throughout the summer.
