Dry Spring, Low Flows: Drought Pressures Mount in South East England

The UK has experienced an exceptionally dry year so far, and the impact is being sharply felt in South East England. Following one of the driest springs in nearly 130 years, water resources across the region are under significant pressure — with groundwater, river flows, and reservoirs all dipping well below normal levels.

Driest Spring in Over a Century

Spring 2025 (March–May) was the sixth driest on record since 1836. In South East England, rainfall was especially scarce, with May in particular recording just 35% of the long-term average. Combined with a hot, dry June — one of the warmest since records began — this has pushed the region toward early-stage drought conditions.

Stressed Water Environments

Many rivers in the south and east of England are now experiencing “exceptionally low” flows, as classified by the Environment Agency. These low flows have knock-on effects: fish rescues are being undertaken in drying riverbeds, canal navigation is restricted due to low levels, and algal blooms are emerging in stagnant waters.

Groundwater levels are also declining, with recharge from winter and spring precipitation now effectively used up. Vegetation and soils, visible via satellite data, are showing signs of moisture stress similar to that seen during the 2022 drought.

Drought Preparedness and Response

In response to these conditions, the National Drought Group convened in June to assess the situation and coordinate a national response. Water companies have been asked to accelerate leak repairs, promote water efficiency, and prepare for potential restrictions if dry weather persists into late summer.

While a few short bursts of rain have offered slight relief, longer-term forecasts indicate a higher-than-average likelihood of further dry and hot conditions — increasing the risk of extended drought.

What This Means for the South East

For residents, businesses, farmers, and environmental managers in South East England, the message is clear: water stress is building. With summer demand peaking and recharge unlikely before autumn, every drop will count.
