Enniskillen, located in County Fermanagh, is known for its picturesque lakes, rolling landscapes, and of course its frequent rainfall. But why does it rain so much in this part of Northern Ireland?
Suppose you’ve ever wondered why the skies seem to stay grey and the drizzle feels endless. In that case, this article explains the climate patterns, geographical influences, and weather systems that make Enniskillen one of the wettest towns in the UK.
The Climate of Enniskillen: A Wet & Mild Region
Enniskillen experiences an oceanic climate (Cfb in the Köppen classification), which means mild temperatures, high humidity, and frequent rainfall throughout the year. Unlike some parts of the UK that have distinct wet and dry seasons, County Fermanagh sees relatively consistent rainfall across all months.
Key Facts About Enniskillen’s Rainfall:
- Average annual rainfall: 1,600mm – 2,000mm
- Rainy days per year: 200+ days
- Wettest months: October – January
- Driest months: April – June (but still wet by UK standards!)
The Role of the Atlantic Ocean & Gulf Stream
One of the main reasons Enniskillen gets so much rain is its proximity to the Atlantic Ocean. Warm air currents from the Gulf Stream sweep across the ocean, carrying moisture toward the UK and Ireland. When this moist air meets the cooler landmasses of Northern Ireland, it condenses, forming persistent clouds and frequent showers.
Key Weather Patterns Affecting Rainfall in Enniskillen:
Southwesterly Winds – Moist air moves from the Atlantic, bringing frequent rain showers.
Jet Stream – This fast-moving air current can influence storms and prolonged wet periods.
Low-Pressure Systems – These dominate much of the year, pulling in moisture-heavy clouds.
The Effect of Fermanagh’s Landscape on Rainfall
Enniskillen is situated in a relatively low-lying area, but it’s surrounded by hills and uplands that contribute to orographic rainfall.
How Local Geography Increases Rainfall:
- The Sperrin & Cuilcagh Mountains – These upland areas to the west and north force moisture-laden air upwards, cooling it and causing rain.
- Lough Erne’s Influence – Large bodies of water like Lower & Upper Lough Erne help retain moisture, contributing to mist, fog, and increased humidity, which can lead to drizzle.
- Funnel Effect – The wind and rain clouds are often funneled through Fermanagh due to its position in the Atlantic storm path, leading to prolonged wet spells.
Did you know? The wettest recorded year in Fermanagh was 2009, with over 2,100mm of rain!
Why Doesn’t Enniskillen Have a Dry Season?
Unlike Mediterranean climates where rain is seasonal, Enniskillen’s rainfall is relatively constant throughout the year. Here’s why:
Persistent Low Pressure – Ireland and the UK frequently experience low-pressure systems, which encourage rainfall rather than dry conditions.
Limited Continental Influence – Unlike inland European locations, Enniskillen doesn’t benefit from dry air masses that reduce rain.
North Atlantic Oscillation (NAO) – This climatic phenomenon shifts between positive and negative phases, influencing storm activity and wet periods in Northern Ireland.
Even in “dry” months like April or June, showers are still frequent, making truly rain-free periods rare!
Rainfall Comparison: Enniskillen vs. Other UK Locations
To put Enniskillen’s rainfall into perspective, here’s how it compares to other wet locations in the UK:
Location | Annual Rainfall (mm) | Rainy Days per Year |
---|---|---|
Enniskillen, NI | 1,600 – 2,000mm | 200+ |
Manchester, England | 850 – 1,200mm | 140 – 160 |
London, England | 600 – 800mm | 110 – 130 |
Glasgow, Scotland | 1,200 – 1,400mm | 170 – 190 |
Fort William, Scotland | 3,000mm+ | 250+ |
Conclusion: Enniskillen is among the wettest towns in the UK, but it still doesn’t reach the extreme levels of Fort William in Scotland!
Will Enniskillen’s Rainfall Change in the Future?
With climate change, scientists predict that:
- Winters may become wetter, with heavier downpours and flooding risks.
- Summers may see more variability, with occasional dry spells but also intense rainfall events.
- Storms may become stronger, influenced by shifting jet streams and global warming.
However, Enniskillen is likely to remain one of Northern Ireland’s rainiest towns for the foreseeable future!
How to Make the Most of Enniskillen’s Rainy Weather
Even though rain is part of life in Fermanagh, it doesn’t have to ruin your plans! Here are some rain-friendly activities:
- Explore Indoor Attractions – Visit Enniskillen Castle or the Marble Arch Caves.

Pro Tip: The best time to see a rainbow in Fermanagh is just after a shower when the sun peeks through!
Final Thoughts: Why Is Enniskillen So Rainy?
- Proximity to the Atlantic brings constant moisture.
- Southwesterly winds & jet stream patterns push rain clouds inland.
- Surrounding hills & Lough Erne increase rainfall and humidity.
- No real dry season, thanks to persistent low-pressure systems.
While the rain may be frequent, it’s also what makes Enniskillen and County Fermanagh so lush, green, and beautiful!
