Flooding expected. Take action now.
High river levels are expected to cause flooding over the next two days.
Flooding is expected on 20 February 2026 as a result of high tides and elevated river flow.
High tide is forecast at 00:30 and 02:00 on the 20/02/2026. The water level is expected to be 4.51 metres Chart Datum (1.77mAOD). The following high tide at 12:45 is forecast to be higher, at 4.74 metres Chart Datum (2.00mAOD). Flooding may affect the access road and car parking areas near the White Swan Pub and the car garage at Mansbridge. Parts of Riverside Park may also be flooded. Levels will be very high at Gaters Mill. Only a small amount of rain is forecast for the next five days. However, flood risk will remain high until flows in the River Itchen decrease.
We are checking rivers for blockages and liaising with Southampton City Council on operation of Woodmill.
Activate any flood protection products you may have , including defences around the White Swan pub.
