The Night of the Big Wind (Irish: Oíche na Gaoithe Móire) was a powerful European windstorm which swept without warning across Ireland beginning in the afternoon of 6 January 1839, causing severe damage to property and several hundred deaths; 20% to 25% of houses in north Dublin were damaged or destroyed, and 42 ships were wrecked. The storm attained a very low barometric pressure of 918 hectopascals (27.1 inHg) and tracked eastwards to the north of Ireland, bringing winds gusts of over 100 knots (185 km/h, 115 mph) to the south before moving across the north of England and onto the European continent where it eventually died out. At the time, it was the most damaging Irish storm for 300 years.^[2][3]
