A cliff collapses at Hastings, ending its role as a trade harbor and demolishing a part of Hastings Castle. New Winchelsea is established on higher ground.

* December – Parts of Norfolk are flooded, the port of Dunwich in Suffolk is further devastated, and in The Fens through the storm and the violence of the sea, the monastery of Spalding and many churches are overthrown and destroyed: "The whole country in the parts of Holland was, for the most part, turned into a standing pool so that an intolerable multitude of men, women and children were overwhelmed with the water, especially in the town of Boston, a great part thereof was destroyed."

* Winter – Two unidentified 'merchants' travel from Alexandria to Cairo to warn Qalawun of the economic dangers posed by Genoese domination in the eastern Mediterranean, which leaves the Mamluk trade at their mercy. Qalawun accepts the invitation to intervene, and breaks the truce with Tripoli.
