A flood warning is in force for Bosham and West Itchenor ahead of Monday's 11am tide. Shore Road and Mill Lane, Sidlesham will flood; spray at Selsey.
The Environment Agency has issued a flood warning for Bosham and West Itchenor ahead of Monday morning’s high tide. Flooding is expected for an hour either side of the 11am tide on Monday 26 October.
A flood warning means flooding is expected and you should act now. It is one step up from a flood alert, which means flooding is possible. The agency issued the warning at 2.06pm on Sunday.
What the warning says will flood
The Bosham and West Itchenor flood warning covers the harbour shore including Chidham, Broadbridge and Bosham Hoe. It says:
- Shore Road will flood
- a small number of properties in Bosham High Street and Gloucester Terrace will be affected
- water will reach the top of the slipways in West Itchenor
The forecast tide is 5.42 metres above chart datum at Chichester Harbour. The weather is adding 0.48 metres to the tide table figure, with a strong southerly force 6 wind.
Tonight’s tide as well
An earlier flood alert for Thorney Island to West Itchenor, issued at 11.35am, covers Sunday night too. It says flooding is possible for an hour either side of the 10.30pm tide tonight. Shore Road will flood, and at Bosham High Street water will be near to or over front door steps.
Selsey, Sidlesham and the Witterings
Two more flood alerts cover the open coast for Monday’s 11am tide. Flooding is possible for two hours either side of it.
The Selsey Bill to Elmer alert says Mill Lane in Sidlesham will flood, making access more difficult for a while. Strong winds and large waves will throw spray over beach-top homes and nearby roads in Selsey and Pagham.
The West Wittering to Medmerry alert warns that the tide may reach the top of the beach at Bracklesham. Water could flow into the ditches behind it. Spray will reach beach-top properties at the end of West Sands Lane and at Medmerry. The agency’s advice there is plain: avoid Medmerry seafront at high tide.
| Area | Tide | What the Environment Agency expects |
|---|---|---|
| Bosham, West Itchenor | Sun 10.30pm | Flooding possible: Shore Road, Bosham High Street door steps |
| Bosham, West Itchenor | Mon 11am | Flood warning: Shore Road, High Street, Gloucester Terrace, Itchenor slipways |
| Selsey to Elmer | Mon 11am | Mill Lane, Sidlesham floods; spray on Selsey and Pagham seafront |
| West Wittering to Medmerry | Mon 11am | Tide to top of beach at Bracklesham; spray at West Sands Lane and Medmerry |
After Monday morning
The agency expects Monday night’s tide, around 11.15pm, to be about 34cm lower and to cause no flooding. Tuesday’s tides should be lower again.
It is watching Wednesday. The midday tide that day is predicted to reach 2.4 metres above ordnance datum, which the warning says may cause minor flooding of low-lying land around the harbour.
The agency will update all four messages by 6pm on Monday, or sooner if things change.
What it means for you
- Do not drive along Shore Road, Bosham around the 10.30pm tide tonight or between about 10am and noon on Monday, the window the warning gives.

- Sidlesham: allow for Mill Lane being under water around Monday’s late morning tide.
