*** 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 Slaney as it flows past Wexford town opens into the large, sheltered Wexford Harbour, a tidal estuary where river water mixes with the cooler Irish Sea. Water temperatures in the estuary reflect a blend of these influences, typically ranging from 6∘C (43∘F) during the coldest winter months to around 16∘C (61∘F) in late summer. This temperature profile means the water is generally quite chilly for swimming, making it uncomfortable without a wetsuit, even in peak summer.
Direct, casual swimming in the River Slaney and Wexford Harbour is not formally prohibited, but it is discouraged due to strong tidal currents, cold temperatures, boat traffic, and historical water quality concerns, which are monitored by local authorities. Instead of river swimming, visitors to Wexford often enjoy water activities like boating, kayaking, and seal watching in the estuary, or they head to the coast for safer, monitored seaside bathing beaches such as Curracloe. Beyond the water, nearby attractions include the Irish National Heritage Park, the beautiful Johnstown Castle and gardens, and the iconic Hook Lighthouse on the Hook Peninsula.
