The largest wave ever recorded off the Irish coast surged on Monday during Storm Ophelia.
A wave of 85.6 feet (26.1m) surged over a gas platform of Kinsale Energy off the Cork coast.
That same gas platform had been the site of Ireland's previous record-setting wave of 82 feet, during Hurricane Darwin in 2014. Another record-breaking wave was reported in 2016.
To put it in context, 85.6 feet is approximately the size of a six-story building.
A wave of that height is fitting for what meteorologists and climatologists have concluded was the strongest eastern Atlantic storm on record, dating back to the 1800s, as Dr. Kieran Hickey of Universty College Cork told the Irish Times.
He also said that the fastest wind of Ophelia was recorded at 119 miles per hour, at the Fastnet lighthouse off the south-east coast.
