Water Temperature: Daily Trends, Historical Records, and Forecast

⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast

Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.

Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information

Upper Lough Erne, an extensive and island-dotted freshwater lake in County Fermanagh, Northern Ireland, is characterized by its typically cold waters. While temperatures fluctuate seasonally, the lake remains cool throughout the year. In the depths of winter, the water temperature commonly settles in the range of 7∘C to 10∘C (45∘F to 50∘F). During the height of summer, the surface waters warm up to their peak, generally reaching about 15∘C to 18∘C (59∘F to 64∘F), though deeper sections remain colder.

Swimming is generally allowed in Upper Lough Erne, forming part of a popular wild swimming culture in the Fermanagh Lakelands. However, swimmers must exercise caution, as the lough is not a designated bathing area and lacks lifeguard patrols. Hazards include boat traffic, cold shock, and underwater obstacles, making wetsuits and swimming with a buddy highly advisable. The lough is a central feature of the Fermanagh Lakelands, and nearby attractions include the magnificent Crom Estate, the natural wonder of the Marble Arch Caves, and the historic town of Enniskillen.
