*** 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 Boderg, a lough on the River Shannon in County Leitrim, features water temperatures typical of an Irish inland lake, which fluctuate significantly with the seasons. During the height of summer, the water may reach its warmest range, roughly between 15∘C and 18∘C (59∘F to 64∘F). Conversely, winter temperatures are quite cold, generally falling between 6∘C and 9∘C (43∘F to 48∘F). Given its position on a major waterway, temperatures can also be influenced by the flow of the river.
Swimming in Lough Boderg is generally allowed as part of the wild swimming tradition in Ireland, with no strict laws prohibiting it, although no official facilities are usually present. Local knowledge suggests a jetty on the lake is popular with outdoor swimmers, allowing for an accessible dip, but swimmers must always exercise caution due to boat traffic on the Shannon Navigation and the cold temperatures outside of mid-summer. Close to the lough, visitors can explore Derrycarne Wood and its easy walking trails, or the charming town of Carrick-on-Shannon, a major hub for cruising and watersports on the River Shannon.
