*** 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
Kinsale is a picturesque harbour town where the River Bandon meets the Atlantic, forming a large estuary. The water temperature here is heavily influenced by the sea, remaining cool throughout the year. In the winter months, the estuarine water temperature typically hovers between 8∘C and 10∘C (46∘F to 50∘F). During the height of summer, the waters are at their warmest, ranging from approximately 15∘C to 18∘C (59∘F to 64∘F), which is considered cold for casual swimming.
While the inner river area itself is not designated for bathing, sea swimming is popular and safe nearby. The sheltered Dock Beach on the Castlepark peninsula is suitable for bathing, and local groups regularly swim around Sandycove Island, which is well-known in the open-water swimming community. Kinsale is renowned as Ireland's Gourmet Capital and is rich in history, boasting major attractions like the spectacular star-shaped Charles Fort and the Old Head of Kinsale, a dramatic cliff-top peninsula.
