*** 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
Lough Ennell, situated near the town of Mullingar in County Westmeath, is a large, shallow, natural lake popular for recreation. Like most inland lakes in Ireland, its temperature is typically cold, but the shallow nature of the lough allows the surface water to warm up more than deeper bodies. Expect winter temperatures to hover between 5∘C and 8∘C (41∘F to 46∘F), while in the summer, the surface can warm up considerably, often reaching 16∘C to 19∘C (61∘F to 66∘F), making it relatively welcoming for a quick dip.
Swimming is generally permitted and encouraged at Lough Ennell. Specifically, the site at Lilliput is a designated bathing water, meaning its water quality is regularly monitored by the Environmental Protection Agency and has been rated as Good. This official designation confirms its suitability for safe public bathing, although temporary restrictions may be put in place, usually due to heavy rainfall or the occasional detection of blue-green algae. Beyond swimming, visitors can explore the magnificent Belvedere House and Gardens estate, which sits on the lake’s eastern shore, or enjoy the boating and fishing opportunities available from the Lilliput shore.
