Flood Alert Active Warning

Raised: 25 Oct 2026 at 11:48am • Updated: 25 Oct 2026 at 11:48am
High tides on Sunday may lead to flooding.
Flooding is possible for 2 hours either side of Sunday evening's tide at 22:15 on 25/10/2026.
The weather increases tide table values by 0.49 m. Total forecast tide is 7.14 metres Chart Datum (3.62 mAOD) at Newhaven. Strong winds and large waves will generate a small amount of spray overtopping which will affect footpaths, sea front parking and the road at Marine Parade and the Esplanade. Monday morning’s tide at 11:00 on 26/10/2026 is forecast to be 15cm higher.
Similar, minor flood impacts are expected on Monday morning.
Monday evening’s tide at 23:00 will be significantly lower, but with strong winds and large waves a few minor flood impacts could again be possible.
We are checking flood defences .
Don't put yourself or others at risk.
This message will be updated by 6:00PM on Monday 26 October or as the situation changes.
