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 Nore flows through the scenic heart of southeastern Ireland, passing through Counties Laois, Kilkenny, and Waterford before joining the River Barrow near New Ross. Its water temperature varies with the seasons, reflecting the mild inland climate and steady flow typical of Irish rivers. In winter, surface temperatures usually range between 4–6°C (39–43°F), while in summer they rise to around 15–18°C (59–64°F). On calm, sunny days in July or August, sheltered sections of the river may briefly reach 19°C (66°F), though deeper areas stay cooler. These moderate temperatures, combined with good water quality in many stretches, make the Nore pleasant for outdoor activities during the warmer months.
Swimming in the River Nore is allowed in suitable areas and has become more popular, especially near Kilkenny city and Thomastown. The river’s flow is gentle in some stretches but can be strong near weirs or after rain, so local knowledge and caution are advised. During summer, swimmers often enjoy short dips or open-water sessions, with wetsuits useful outside peak season. Beyond swimming, the River Nore is valued for kayaking, fishing, and riverside walking trails. Kilkenny’s medieval architecture, bridges, and castle overlook the water, creating a setting where history and nature blend harmoniously.
