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

Lough Cullin in County Mayo is part of a freshwater complex with the larger Lough Conn, to which it is joined by a narrow channel at Pontoon. The lake water temperature follows the general trend for Irish loughs. It is chilly during winter, typically ranging from 5∘C to 8∘C (41∘F to 46∘F), with the surface layer warming up in the summer months to a more accessible 14∘C to 18∘C (57∘F to 64∘F) on average.

Swimming is generally permitted and enjoyed as a form of wild swimming in Lough Cullin, as it is a natural lough and not a drinking water reservoir with prohibitive regulations. However, swimmers should exercise caution due to the large, deep nature of the water and the lack of official lifeguards or designated bathing areas. The lake and its surrounds are internationally renowned for brown trout and salmon fishing. Other nearby points of interest include the Foxford Woollen Mills in the nearby town of Foxford and the National Museum of Ireland – Country Life at Turlough House.
