*** 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
Kilkenny City is bisected by the River Nore, a beautiful waterway flowing through the heart of Ireland's Medieval Mile. The water temperature is typical of an inland Irish river, exhibiting a distinct seasonal range. In the cold winter months, the Nore can drop to around 2∘C (36∘F), while the summer sees it peak at roughly 15∘C (59∘F). This temperature profile is only suitable for experienced or very acclimatised swimmers, and a wetsuit is often advisable.
While not officially designated as a bathing water site along its entire length, specific spots on the river, such as The Weir and Bishops Meadows in Kilkenny City, are commonly used for swimming, and lifeguards may be on duty during the peak summer season. However, temporary swimming prohibitions are occasionally put in place due to fluctuating water quality and high bacteria levels, making it crucial to check local council warnings before entering the water. Beyond the river, visitors flock to Kilkenny Castle, St. Canice's Cathedral, and the numerous craft and design centres that define the area.
