The biggest wave ever to hit Irish shores has been recorded, weather experts have revealed today.

The monster 67-footer was measured at a special buoy off the Donegal coast today as a force-10 storm raged across the north coast.

Meteorologists at Met Éireann said data from the sea conditions about 60 miles to sea were the most severe it has encountered that distance offshore.

“At 14.00 today the M4 weather buoy off the Donegal coast recorded a maximum wave height of 20.4 metres which is the highest maximum wave recorded in Irish waters,” Met Éireann reported.

At Malin Head, the northerly most tip of Ireland, wind gusting to 140km/h was recorded.

Elsewhere, the Irish Coast Guard has urged people to stay off exposed coasts, cliffs, piers, harbour walls, beaches, promenades during this week’s forecast stormy weather.

Winds and stormy conditions will ease tonight before freezing conditions hit Ireland on Thursday and there is a risk of a second storm hitting the south and midlands.

Forecasters, however, said there is a chance the storm may miss Ireland to the south.

The Weather Buoy project is a collaborative project between the Department of Transport, Marine Institute, Met Éireann and the UK Met Office.

Monster Waves

As a slight drift!, wave rider buoys are all over the world, usually called 'odas' buoys on the charts. We have several off the Portuguese coast, which can be accessed on line to display live swell data, sea temperature, graphs, and historical data.

I have just looked at our 'local' buoy data on line - we have about 10m now, and it was up to 12m earlier today - not up to Irish standards!

Additionally, the site linked above gives all the usual hydrographic data, such as tide times, local notices to mariners and much more. It is in Portuguese but not difficult to understand.

Cheers,

Michael.

Once upon I time I read that the theoretical limit for the height of a sea wave is around 100ft.... BUT..... I also read that in the Southern Ocean , when waves going in opposite directions collide , the "handclap" wave can exceed that.....eeeeeeeK!
Sweet dreams!!
