Period: From May 2025
Issued on 14.05.2025 using data to the end of April 2025
The outlook for May is for below normal river flows across most of the UK, except southern Wales and south-west England, where flows are likely to be normal. Groundwater levels are expected to continue to decline in most areas, although above normal levels are likely to persist in parts of the southern chalk. Over the period May-July, river flows in most areas are likely to continue to be below normal, with the potential for current low to exceptionally low flows to persist in some catchments. Flows in western Scotland and Northern Ireland are likely to be normal.
