Anyone heading for Brighton beach tomorrow is being warned to watch out for bigger waves than usual and to steer clear of low-flying pebbles.
The warning comes as more than half an inch of rain – or more than 13mm – is expected to fall overnight from late tonight (Saturday 28 September) until mid-morning tomorrow.
And the Met Office has forecast winds gusting at more 50mph, with an especially high tide due at lunchtime.
Brighton and Hove City Council said: “Strong winds, large waves and beach shingle could cause injury. Please take care.
“A very high tide along Brighton and Hove beaches will be at its highest at 12.23pm on Sunday 29 September.
“This coincides with a Met Office weather warning of strong winds up to 45mph to 55mph along the coast, especially in exposed locations.
“The waves will be very high and strong and we’re expecting some ‘overtopping’ and shingle to blow off the beach.
“This can cause injury – and the waves also have the potential to also knock people over.
“Please be very careful if you’re planning to visit Brighton and Hove beaches on Sunday between 10am to 2pm.”
