Use the drought risk assessment tool to explore conditions through our interactive map. This tool shows the number of days that river flows have been very low and is used to help identify areas at greater risk of long-term ecological impacts. When river flows have been very low for 30 or more days, Significant Scarcity is reached. Data is updated daily at 0930 GMT / 1030 BST.

Conditions overview

  • Rainfall - Recent rainfall has largely been within the normal range for this time of year. More prolonged rainfall is needed to significantly improve conditions in eastern catchments.

  • River flows - Low to very low river flows persist across much of eastern Scotland, with several rivers falling below the low flow threshold again this week. The west continues to experience normal to high flows, with very high flows in parts of the northwest.

  • Soil/ground conditions - Ground conditions remain dry across parts of eastern Scotland.

  • Groundwater and loch levels - Across the east of the country levels remain very low for the time of year. In Dumfries and Northern Scotland levels are within the normal range for the time of year. Loch levels show a mixed picture, with most sites normal to high levels. However, Lochindorb, to the east of Inverness, has a low level.

Weather forecast

  • Mainly dry start to Thursday but rain will spread east through the afternoon and evening, turning heavy at times especially in the west. The rain will continue into the night and then turn showery on Friday morning. The showers will continue through the rest of Friday and Saturday, heavy at times and most frequent across the West Highlands, while the southeast should escape most of them. A drier day on Sunday then more rain crossing the country on Monday. © Crown copyright [2026], Met Office

Advice for water users

Everyone should plan to increase their resilience to the impacts of prolonged dry conditions. By taking the right steps now, it could help reduce the impact of water scarcity in the future. For further information visit Advice for abstractors and irrigators

Rainfall and river flows

These maps show rainfall and river flows relative to the long-term average, for this time of year, over 1 month, 3 months, and 6 months.

Recent rainfall conditions have been generally normal across the country. River flows have continued to be very low in parts of eastern Scotland, while the rest of the country has seen normal to very high flows.

Over the past three months, rainfall conditions have generally been dry to very dry across much of eastern and southern Scotland. In contrast, northern and parts of western Scotland have generally experienced normal to very wet conditions. River flows have remained very low across much of eastern Scotland, with a mixture of normal to low flows in the south-west. In the west and north, flows have generally ranged from normal to very high.

Over the past six months, rainfall conditions have been generally dry to very dry across much of the east of Scotland and in parts of the south-west and Central Belt, with isolated extremely dry conditions. In the north-west, as well as in Orkney and Shetland, rainfall conditions have been normal to very wet. River flows have been very low to extremely low across much of eastern Scotland and the Central Belt. Elsewhere, flows have generally ranged from normal to very high, with areas of quite low flows in the south-west.

Soil moisture deficit

This week's report

This map shows this week’s soil moisture deficit. This is obtained from the Met Office Rainfall and Evaporation Calculation System (MORECS). Ground conditions are generally quite dry to dry across parts of eastern Scotland. Elsewhere, conditions are normal.

Natural water storage – groundwater and loch levels

In each river catchment there is some degree of natural water storage, which can maintain river flows even when it is not raining. This natural water storage is mainly held in lochs and groundwater. When storage has been depleted it will take a lot of rainfall for levels to recover.

The maps below show recent groundwater and loch level compared to the long-term record at each individual station. Level is reported as high or low compared to the typical (‘normal’) level range for the time of year.

Level ranges are specific to each station and based on the long-term (minimum 10 years) record of mean monthly level values recorded at individual stations. 

Despite recent rainfall groundwater levels remain low across much of the country. Across the east of the country levels remain very low for the time of year. In central Fife, levels at the Newton of Falkland borehole for September have only been lower in 2006 and 2025. Monitoring boreholes in Aberdeenshire, Angus and East Lothian were also very low for September. In Dumfries and Northern Scotland levels are within the normal range for the time of year.

Loch levels show a mixed picture, with most sites normal to high levels. However, Lochindorb, to the east of Inverness, has a low level.
