Ahead of tomorrow’s expected wavefest [graphic above].

Right in the path of tomorrow’s swell we have one of the longest running monitoring stations providing wave data, the Sevenstones Light Vessel.
For this it’s typical to calculate what’s called a 50 or 100-year return period. This is simply the size of the largest waves you could expect will definitely occur at least once in that timeframe.
For the Sevenstones Light Vessel, with our long historic record, we can do this with some accuracy. In fact, analysis as early as the 1970s had already identified these values in the 36-40ft range.
Tomorrow’s storm is currently forecast to peak at 37ft in deep water around Western Cornwall. If these values are confirmed by the wave buoy tomorrow then we are looking at an event near that 50 year return period range – that is to say ‘infrequent’ but not necessarily ‘unusual’.
How BIG will they be in Ireland anyone?
