*** 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
The River Shannon flows directly through Limerick city, and its temperature is highly influenced by the seasons. In the winter months, the water can be quite cold, typically ranging from approximately 6∘C to 10∘C (43∘F to 50∘F). As summer progresses, the river warms up, with temperatures generally reaching between 15∘C and 18∘C (59∘F to 64∘F) in the city area, though this can occasionally be slightly warmer in prolonged heat.
Swimming in the River Shannon in Limerick is not widely practiced or officially promoted due to safety concerns, primarily related to strong currents, tides in the lower, tidal sections, and potential water quality issues. While official public bathing areas are rare, organized open-water swimming events, such as the annual Limerick Island Swim, do take place with extensive safety measures. For visitors, the city offers land-based attractions like the historic King John's Castle overlooking the river and the culture-rich Hunt Museum in the city centre.
