The 10th of  March saw one of the largest Spring Tides of  2008. This was combined with very low atmospheric pressure (around 960mb) and a severe gale (SSW early, becoming WNW by afternoon). These conditions combined to generate a very big sea, the swell exceeded 35’ at Sevenstones off  Land’s End,  and an actual tide which exceeded predicted levels by > 1 metre.

There was some damage done by the wind, but the gusts were not that exceptional, typical of a severe winter gale. Maximum gusts in west Cornwall generally in the range 70-85mph. However the size of  the swell, combined with the exceptionally high sea level, created some spectacular and dangerous  conditions along the coast, together with some flooding along various parts of the north Cornwall coast.

height was not exceptional. The peak significant wave height at Sevenstones off Lands End was 8 metres. 11 metres has a         
5 year return period. The swell might have been unexceptional, but the wind was damaging. Peak gusts were 82mph at Lands End,  
93mph at Tol Pedn on Gwennap Head.
