Period: From July 2025      Issued on 09.07.2025 using data to the end of June 2025

Rainfall: 

June rainfall saw a marked east-west contrast. Western areas, particularly parts of north-west England and western Scotland, recorded above average totals. Meanwhile, much of central and eastern England experienced a dry month, with large areas in central England receiving less than half the average rainfall for June. The latest Met Office forecast (issued 30.06.2025) indicates that the chances of either wet or dry conditions for both July and the July-September period are evenly balanced.

River flows:

River flows in June were generally within the normal to above range across western catchments, with some exceptionally high flows recorded in north-west England. In contrast, flows were below normal across much of the rest of the UK, with notably or exceptionally low flows observed in many catchments in eastern Britain and central and eastern England, some receiving only around a third of their average June flows. The outlook for July reflects recent unsettled conditions in the west, with normal to above normal flows expected in western Britain. Elsewhere, below normal to low flows are the most likely outcome, with some catchments likely to continue experiencing notably or exceptionally low flows.  The July-September outlook suggests a continuation of this geographical contrast, with normal flows most likely in western Britain and below normal to low flows expected elsewhere. Some catchments may remain significantly below normal throughout the period.

Groundwater:

Groundwater levels in June were generally within the normal to below normal range across the UK, with notably low levels in Northern Ireland, east-central Scotland and south Wales. The outlook for July indicates that groundwater levels are likely to remain normal to below normal across most areas, with notably or exceptionally low levels expected to persist in some areas. Localised above normal levels may occur in slower-responding boreholes, such as those in the Chilterns. For the July-September period, normal to below normal levels are the most likely outcome across the country, although a gradual trend towards normal is possible in some areas.
