Night of the Big Wind

Date: January 6, 1839 • Location: Dublin City, Ireland

The worst storm to impact Ireland in 300 years damaged or destroyed more than 20 per cent of houses in Dublin with 100-knot (190 km/h) winds.

The Night of the Big Wind was a powerful European windstorm that swept across what was then the United Kingdom of Great Britain and Ireland, beginning on 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 918–922 hPa (27.1–27.2 inHg) and tracked eastwards to the north of Ireland, with gusts of over 100 knots before moving across the north of England to continental Europe, where it eventually dissipated. It has been described as probably worst storm to hit Ireland in the last 300 years. Liverpool also suffered severely, with many shipwrecks and much structural damage. 120 people died as a result of such accidents in the city alone. Two major shipwrecks resulted in damage of at least £500,000, equivalent to £45,000,000 in 2025.
