Waves as high as four metres have been crashing against beach huts and flooding onto roads on the Felixstowe seafront.
One eyewitness reported seeing water hitting the huts with such force that they moved backwards towards the road running behind the beach.
The increase in wave height correlates with the exceptionally high winds seen across the county over the past couple of days.
Weather forecaster Adam Dury said, at their biggest, waves have reached three or four metres high. This is compared to the ordinary height of roughly one metre.
He said the wave height increase was to be expected as winds as high as 40mph have blown across Suffolk’s coastal areas.
Fortunately, sea swells are looking to decrease this afternoon as the winds die down and change to a south easterly direction.
Mr Dury added that increased wave heights were normal during periods of high easterly winds.
