Direct answer: the last UK hurricane
The most recent storm that met the UK Met Office definition of a hurricane was Storm Eunice on 18 February 2022, with sustained winds of 122 km/h (66 kt) measured at The Needles and a gust of 127 mph (204 km/h) recorded on the Isle of Wight. The preceding UK hurricane was Storm Dennis on 15–16 February 2020, which brought a gust of 124 mph (200 km/h) at Gwennap Head in Cornwall. Both events were named, tracked closely, and caused widespread disruption, yet true hurricane-force conditions remain rare in the UK.
Why the UK very rarely sees hurricanes
UK hurricanes are uncommon because sea surface temperatures around Britain are usually too cool to sustain the deep convection and warm-core structure that define hurricanes, and the prevailing wind patterns steer most tropical systems away or disperse their energy. When storms do track into the North Atlantic and UK area, they are often extratropical or transition into hybrid systems that still produce damaging winds but do not meet the strict thermal definition of a hurricane used by forecasters.
Key ingredients needed for a UK hurricane
- Very warm sea surface temperatures, typically above 26–28°C through a deep layer.
- Low vertical wind shear to allow the storm’s core to remain organized.
- A pre-existing disturbance that can draw in sufficient moisture and spin.
- Favorable large-scale steering flows to steer the system northward into the UK sector.
Recent storms that affected the UK and how they were classified
Several impactful European windstorms have struck the UK in the last decade. The table below distinguishes which were officially classified as hurricanes at landfall in the UK and which were strong extratropical storms or remnants of tropical systems.
| Storm | Date | Max UK gust | Met Office classification at UK landfall | Notes |
|---|---|---|---|---|
| Storm Eunice | 18 February 2022 | 127 mph (204 km/h) on the Isle of Wight | Hurricane | Named by the Met Office; caused widespread damage and travel disruption. |
| Storm Dennis | 15–16 February 2020 | 124 mph (200 km/h) at Gwennap Head, Cornwall | Hurricane | Triggered severe weather warnings and flooding across parts of the UK. |
| Storm Dagmar | 105 mph (169 km/h) at Needles Old Battery, Isle of Wight | Storm | Strong extratropical system, not classified as a hurricane. | |
| Storm Franklin | 21–22 July 2021 | 87 mph (140 km/h) at Capel-le-Ferne, Kent | Storm | Post-tropical cyclone remnants; heavy rain and gales but not hurricane-force. |
What defines a hurricane in the UK context
The Met Office uses a practical operational definition aligned with the World Meteorological Organization guidance: to be called a hurricane at landfall in the UK, a storm must have sustained winds over 64 knots (119 km/h) and a warm-core tropical structure at the surface, typically evidenced by a clear central eye or tight spiral burst near the centre. Many storms that reach the UK have hurricane-force gusts but are classified as strong extratropical cyclones because their structure and energy source differ from tropical systems.
National thresholds used by the Met Office
- Hurricane-force: Sustained winds exceeding 64 knots (119 km/h).
- Storm-force: Sustained winds between 48 and 63 knots (89–118 km/h).
- Gale-force: Sustained winds between 34 and 47 knots (63–88 km/h).
Seasonality and return periods
Tropical cyclones in the North Atlantic peak from August through October, but by the time they reach the latitude of the UK—often after interacting with the jet stream and mid-latitude westerlies—they have usually lost tropical characteristics. Storms that retain enough warmth to qualify as hurricanes at landfall are rare; on average, the UK experiences a named storm with hurricane-force winds every 5–10 years, while direct hits with clear hurricane-force gusts are less common. Most impacts arise from the remnants of Atlantic hurricanes or from intense extra-tropical systems that draw energy from steep temperature gradients rather than latent heat release.
Practical impacts and preparation tips
When a storm does reach UK shores with hurricane-force winds, the risks include travel disruption, power outages, and damage to property. Preparing for severe weather can reduce harm and speed recovery. Follow official guidance from the Met Office and local authorities, and take sensible precautions ahead of high winds.
Recommended preparations before a severe windstorm
- Secure loose outdoor items such as bins, garden furniture, and signage.
- Trim trees and check for damaged branches that could fall.
- Check your insurance and keep emergency contacts handy.
- Charge devices, have torches and batteries ready, and avoid unnecessary travel during peak gusts.
Looking ahead: climate influences and monitoring
There is ongoing research into how climate change may affect the intensity and tracks of North Atlantic hurricanes and their likelihood of reaching the UK. While no definitive conclusion exists, a warmer atmosphere can hold more moisture, which may increase rainfall rates if a tropical system remains energetic near the UK. Continuous monitoring by the Met Office, ECMWF, and other centres helps ensure timely warnings and accurate classification when storms approach.
Summary and key takeaways
- The last UK hurricane was Storm Eunice on 18 February 2022, with a gust of 127 mph recorded on the Isle of Wight.
- The previous UK hurricane was Storm Dennis on 15–16 February 2020.
- UK hurricanes are rare due to cooler SSTs and prevailing wind patterns that generally steer or weaken tropical systems.
- Notable UK windstorms are often extratropical remnants of Atlantic hurricanes rather than tropical hurricanes at landfall.
- Preparation and staying informed via the Met Office are the best ways to reduce risk during severe wind events.
