*** 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.

The River Annalee, flowing through County Cavan, is a typical inland Irish river, meaning its water temperatures are considerably colder than coastal waters. During winter, the temperature generally ranges from 4∘C to 8∘C (39∘F to 46∘F). Even in summer, river temperatures are bracing, peaking at about 14∘C to 17∘C (57∘F to 63∘F), which can cause thermal shock.
While no specific official bathing areas are monitored along the Annalee itself, swimming is generally permitted in Irish rivers unless otherwise signposted, with safety being the primary concern due to currents, depth changes, and water quality that can fluctuate. Wild swimming is enjoyed locally in some quieter stretches, but it is not officially supervised. The Annalee and its tributaries are better known for fishing, particularly for trout and pike. Nearby attractions in the Lakeland County of Cavan include Killykeen Forest Park and the historic Clough Oughter Castle on Lough Oughter.
