*** 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
Athlone, a vibrant town in the heart of Ireland, sits on the banks of the River Shannon, where the wide, steady waters flow south from Lough Ree. The river’s temperature in this area reflects Ireland’s mild inland climate. During winter, the water usually stays between 4–6°C (39–43°F), while in summer it warms to around 15–18°C (59–64°F). On warm, sunny days in July or August, shallow stretches and sheltered areas can briefly reach 19°C (66°F), though the main channel remains cooler. These moderate temperatures make the water refreshing but suitable for swimming during the warmer months, particularly from late May through early September, when air temperatures are also comfortable.
Swimming in the River Shannon at Athlone is allowed and increasingly popular, especially near supervised or recognized entry points. Local open-water groups often swim in the town stretch during summer, taking advantage of the calm, clean water. Safety precautions are important, as currents can vary and boats frequently use the navigation channel. Many swimmers wear wetsuits to extend their season beyond midsummer. Beyond the river, Athlone offers rich attractions including Athlone Castle, scenic riverside walks, and the nearby Lough Ree, known for boating and fishing. Together, they make Athlone an appealing destination for both recreation and culture.
