Flows in the Lower River Itchen are high and increasing. In the last 24 hours, 35mm of rain has been recorded at Portswood. Monday's early morning tide at 03:15 on 06/01/2025 and 04:30 on 06/01/2025 is higher than normal due to unsettled weather, with strong Southerly Force 6 winds. The weather increases tide table values by 0.88 m. The total forecast tide is 5.27 metres Chart Datum (2.53 mAOD) at Southampton. For 2 hours either side of high water, levels in the Lower River Itchen will rise as the incoming tide prevents water flowing out to sea. At Mansbridge, the pub car park will flood. Footpaths will flood throughout Riverside Park. In some places, it will be very difficult to see the edge of the river bank.
