The highest wave ever recorded in Irish waters was recorded off the coast of Donegal yesterday afternoon, according to Met Eireann.
The M4 weather buoy, positioned approximately 16km west of Rossan Point, recorded a maximum wave height of 20.4 metres or 67 feet.
The maximum wave height, recorded just after 2 o clock yesterday afternoon, was the highest ever recorded in Irish waters, Met Eireann said on their website.
The new record toppled an earlier record wave which was also recorded at the bouy yesterday morning.
Just after 11 o clock yesterday morning a record wave of 20.2 metres was recorded.
Met Éireann said a storm passing to the North of Ireland coupled with westerly winds feeding in behind it were likely to have created the record wave.
