⚠️ 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.

*** 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 Allua, a picturesque ribbon lake in County Cork that forms part of the River Lee, is primarily known as an excellent spot for coarse fishing. Due to the lack of official monitoring and its inland location, precise seasonal water temperature figures are difficult to obtain. However, as a large, deep freshwater lake in the south-west of Ireland, its waters are typically very cool, even in summer. Estimated temperatures would likely range from a winter low of around 4∘C to 8∘C (39∘F to 46∘F), peaking in summer at approximately 14∘C to 18∘C (57∘F to 64∘F).

Swimming is generally allowed in Lough Allua, as public access to open water is rarely restricted in Ireland. The lake is, in fact, the location for an annual open water charity swim event, which confirms its suitability for bathing. Nevertheless, as there are no designated bathing areas, no lifeguards, and the water is deep in sections, caution and local knowledge are essential for safety. The lough is situated close to the Gougane Barra Forest Park, a beautiful area famous for its scenic drive, walking trails, and the tiny St. Finbarr’s Oratory on an island in a nearby lake.
