In 2004, fish rained down on the Welsh town of Knighton, as reported by the BBC, startling residents and adding to the long history of animal rain in the British Isles. The fish were likely swept up by a waterspout from a nearby river or body of water. The event was documented in local and national news, reigniting interest in the phenomenon.

The Knighton fish rain was noted by contemporary Welsh poets, who saw in it a continuation of the Celtic tradition of marvels and portents. The event inspired poems and creative works exploring the relationship between the ordinary and the extraordinary in the Welsh landscape, echoing the work of poets like Dylan Thomas and R.S. Thomas.
