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 Fergus is a major waterway in County Clare, Ireland, renowned for its clarity and for flowing through the county town of Ennis before reaching the Shannon Estuary. As a freshwater river in the temperate Irish climate, its water temperature remains quite cool throughout the year. Typically, seasonal ranges fall between 8∘C to 17∘C (46∘F to 63∘F), with the warmest period occurring in late summer and the lowest temperatures recorded in winter. These temperatures mean that the water is always cold and usually necessitates a wetsuit for any prolonged period of immersion, even in the milder months.
Swimming in the River Fergus is generally not officially designated or promoted in many urban sections, primarily due to safety concerns regarding currents and boat traffic, as well as fluctuating water quality, though this can vary locally. While no blanket law strictly prohibits swimming in Irish rivers, it's advised to stick to designated and monitored areas. However, its connecting body of water, the Shannon Estuary, and nearby freshwater attractions like Lough Derg on the River Shannon, offer dedicated blue-flag bathing spots. Those visiting the area can also explore the historic Ennis Friary, the narrow medieval streets of Ennis town, or the famous Cliffs of Moher and the unique landscape of The Burren which are all within a short distance.
