Groundwater flooding in Patcham

Flooding possible. Be prepared.

Flood alert

Groundwater is high but stable at Ladies Mile borehole. A small amount of water could appear in a few basements. Previous events suggest impacts may initially affect Old London Road, Patcham and Peacock Lane, Withdean. A small amount of water may appear on roads. Isolated showers are forecast Tuesday, with the potential of another 10-20mm of rain Wednesday evening. Followed by showers through the second half of the week. Groundwater may slowly rise again at Ladies Mile borehole from Thursday evening, through to Monday (16/02/2026), but probably not far, and may instead remain stable or fall. The weather outlook remains unsettled. More rain is predicted on Sunday and Monday (16/02/2026). It is possible that groundwater at Ladies Mile will rise again next week, through to 22/02/2026, but depends on amounts and intensity of rain, which is uncertain. In Patcham village, groundwater will probably continue to steadily rise through to at least the last week of February. Ensure pumps work. We are liaising with Brighton and Hove City Council. We will update this message by 18:00 14/02/2026.
