In 1910, Ilfracombe was washed by a huge wave, one of a kind, they called it tidal wave. Witnesses say that it was up to 20 feet in height and it swept away almost everything that came into the way. There are several stories about the tidal wave, but the most detailed story comes from
Ilfracombe Gazette and Observer souvenir pamphlet containing eyewitness reports and photographs. At Ilfracombe,
a tremendous tidal wave swept over the Capstone Parade, and the Ropery Meadow, breaking upon the Promenade shops with terrific force. . . . Practically the whole of the damage was done by a huge tidal wave. . . . It is a rather remarkable fact that although this was nearly an hour after high tide comparatively little damage was done till then. The huge wave broke upon the shore with almost incredible force. It carried everything before it. The lampposts on the Parade were about the first to go. These were snapped off like fragile reeds. Heavy seats and big blocks of masonry were carried upon the crest of the wave, which swept over Ropery Meadow at a height estimated at from 15 to even 30 feet [approximately 4–9 meters] high, leaving ruin and wreckage in its path. The wall of Ropery Meadow yielded before it, and the masonry and the Parade seats were hurled with tremendous force against the Promenade shops. The Promenade was immediately a rushing torrent. Several people narrowly escaped injury. On seeing the huge wave approaching they turned and fled for their lives. Two or three were unable to reach a place of safety before the wave reached them, and were knocked over like ninepins. Others fell in their hurry to get out of danger. It seems remarkable that no one sustained serious injury. (IGO, 1910)
