The largest waves are set to hit from late Friday night and through Saturday Morning, reaching a peak just before high tide along the south Cornwall coast at approx 10.30am.
With the swell changing tack slightly as it approaches, the south coast remains at most risk, however smaller tides than recent days may help.
