Brit.

/ˈsəːf biːt/, U.S.

/ˈsərf ˌbit/

Origin: Formed within English, by compounding. Etymons: surf n., beat n.¹

Etymology: < surf n. + beat n.¹ Compare earlier surf-beat adj., surf-beaten adj. at surf n. Compounds 1a(c).

1. The beating of surf on a shore; an instance of this. Chiefly literary and poetic. Now rare.

ΚΠ

1857 N. Amer. Rev. Jan. 106 The open sea around the Pole, whose surf-beat upon its icy shores was witnessed and heard by our American sailors.

1873 ‘M. Twain’ & C. D. Warner Gilded Age lx. 543 A receding of tides, a quieting of the storm-wash to a murmurous surf-beat.

1918 C. Y. Rice Wraiths & Realities 166 Like the sea's are His mysteries, not to be learned from a single surf-beat.

1927 C. F. Dole My Eighty Years ii. 15 Strange bits of coral and lava and pretty shells, ringing still with the surf-beat of the Pacific.

1944 Life 26 June 41/1 I've heard the endless surf beat of attacks that roll in and smash at a beachhead again and again.

2. Oceanography. The slow rise and fall of sea level at a shoreline at a frequency lower than that of ordinary wind waves, attributed to the interaction of waves of different wavelength.

1949 W. H. Munk in Trans. Amer. Geophysical Union 30 853 The two- to three-minute oscillations shown by the tsunami recorder appear to be caused by the variability of water transport into the surf zone, and are therefore termed ‘surf beat’.

1955 Science 25 Nov. 1006/2 Surf beat associated with the irregularity of the net shoreward transport of water by ordinary surface waves and swell in the surf zone.

1991 P. D. Kovalev et al. in E. N. Bernard Tsunami Hazard 143 These instruments allowed the collection of real-time oceanographic data over a broad frequency band, including tides, surges, tsunamis, seiches, and surf beats.

2007 T. Garrison Oceanography (ed. 6) x. 276/1 The characteristics of surf beat explain why in some instances every ninth wave might be quite large.
