The alert states that large and powerful waves are expected due to spring tides, low pressure and strong winds.
High tide will be between 2.45am and 7.30am on Thursday, November 28. Conditions may apply two to four hours either side of high tide.
Areas most at risk are beaches, promenades, coastal footpaths and roads which may experience minor overtopping and wind-blown spray.
Areas likely to see this are King Edwards Bay, Cullercoats Bay, Whitley Sands Promenade, Seaburn Lower Prom, Port of Sunderland, Hendon Prom and Seaham Harbour.
The Environment Agency has said: “Please be careful along beaches, promenades, coastal footpaths and roads as large waves and sea spray could be dangerous. We are closely monitoring the situation.”
