An interactive map shows that parts of Suffolk could be underwater by 2030, including the towns of Ipswich and Felixstowe.
The sea level rise and coastal flood map created by Climate Central show how much of the county will be flooded in the next seven years and more.
Parts of Felixstowe and Ipswich could be completely underwater.
As shown in the map above, key areas of Felixstowe could be underwater within the next seven years.
This includes the Port of Felixstowe and Felixstowe Ferry.
In Ipswich areas along the River Orwell will be affected first, including Ipswich Waterfront and Portman Road stadium.
Most of the Suffolk coastline including Aldeburgh and Southwold will also be underwater by 2030.
Lowestoft will not see as much damage compared to the rest of east Suffolk but nearby Beccles and Oulten Broad will be flooded by the River Waveney.
West Suffolk does not have as high of a risk as the Suffolk coast.
Data for the map is based on global datasets for elevation and tides in addition to sea level rise projections.
Climate Central does stress that the map includes big datasets "which always include some error".
The Evironment Agency are also concerned about the accuracy of the data.
A spokesperson said: "The prediction does not take into account extensive efforts taken to prevent such severe incidents in the future, including the presence of sea defences, which protect communities from flooding".
"There may also be discrepancies between the climate change scenarios shown on the maps and those we currently advocate as being the most appropriate".
The Environment Agency is investing £5.2 billion between 2021 and 2027 to create around 2,000 news flood and coastal risk management schemes across England.
These schemes will help reduce the nation flood risk by up to 11 percent and reduce the risk of considerable distruption to the lives of over four million people caused by potential future flooding.
