Kent groundwater situation: February 2025

Updated 20 February 2025

Applies to England

Current situation

The first half of February has recorded some widespread rainfall, which maintained the upward trend in groundwater levels. However, the rise has slowed down due to the lack of consistent rainfall.

Groundwater levels are still normal for this time of year in the eastern Kent area.

Short term forecast 

The slowdown of the initial rise in groundwater levels is expected to continue until the end of February. Some spells of rain are predicted, but no heavy rainfall is currently expected in the south east.

Longer term forecast 

Some unsettled weather and spells of rain are predicted for the first half of March. However, drier and brighter periods are also expected to occur in between wetter days.

The levels are not currently predicted to get high enough to cause any flooding. The likelihood of flooding to occur in March and possibly April is dependent on the amount and intensity of rainfall we receive. In addition to the rainfall, the onset and frequency of spring-like (that is, bright) conditions can also influence the likelihood of flooding. If we receive higher than average rainfall from the latter end of February onwards, groundwater flooding of basements and low-lying land could still occur. This may also result in winterbournes such as the Nailbourne, Alkham Bourne and Petham Bourne flowing more extensively. Winterbournes are rivers which flow in winter because of high groundwater levels.

What the Environment Agency is doing 

We will continue to monitor groundwater levels across Kent and provide situation report updates throughout the remainder of this winter. The next report will be published next month unless the situation changes significantly. 

We will take evidence-based decisions. If conditions deteriorate, we will notify our partners (including lead local flood authorities and water companies). We will also actively engage with our partners to help them prepare for incident response.

Actions and advice

There is practical advice on what to do before, during and after groundwater flooding, and further guidance about groundwater flooding, how it might affect you and what to do.

Next update

We will continue to monitor groundwater levels closely and we will provide a further update next month unless there are any significant changes.
