With the impact of climate change leading to rising sea levels and an increase in the number of and intensity of storms, the risk of flooding in Weymouth will greatly increase. The existing harbour walls are already too low to protect Weymouth from major flood events and the sea level in Weymouth is expected to rise a further 1.3m over the next 100 years. For example, it has been estimated that by 2115, 1,600 properties will be at risk of tidal flooding around the harbour alone.
