Latest Outlook

Period: From July 2025

Issued on 09.07.2025 using data to the end of June 2025

The river flow outlook for July indicates below normal to low flows across eastern Scotland and central and eastern England, with some catchments expected to experience notably or exceptionally low flows. In contrast, western areas are likely to see normal to above normal flows. The July to September outlook suggests a continuation of this east-west contrast, with flows remaining below normal to low in central and eastern areas, whilst western regions are expected to be in the normal range. Groundwater levels for both July and the July to September period are anticipated to be normal to below normal across the country.
