The Night of the Big Wind was a powerful European windstorm that swept 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 and tracked eastwards to the north of Ireland, with gusts of over 100 knots (185 km/h; 115 mph), before moving across the north of England to continental Europe, where it eventually dissipated. At the time, it was the worst storm to hit Ireland for 300 years.
