*** 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 Mask is a vast freshwater lake in County Mayo, renowned for its challenging fishing, which influences its recreational use. The water temperature of this Irish lough is generally cold year-round, reflecting its inland location and depth. In the depths of winter and early spring, temperatures can drop to around 8∘C to 10∘C (46∘F to 50∘F). Even during the summer months, the water only warms up modestly, typically peaking between 13∘C and 16∘C (55∘F to 61∘F), making any unassisted swim a bracing experience.
While there are no official Blue Flag bathing beaches, swimming is permitted and practiced, particularly in sheltered bays and accessible points like Tourmakeady Pier, where locals often take a dip. However, due to the cold temperatures, the lack of official lifeguard cover, and the presence of hidden underwater hazards like rocks, swimming is largely considered a form of wild swimming and requires caution. Visitors to the area often explore the nearby picturesque village of Cong, famous for the film The Quiet Man, the ruins of Cong Abbey, and the magnificent Ashford Castle.
