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
Navan, the county town of Meath, sits at the confluence of the River Boyne and the River Blackwater. The River Boyne is generally a cold-water environment, with temperatures fluctuating across the seasons. Based on data near Navan, the water typically ranges from about 4∘C (39∘F) in the winter months to peak around 15∘C (59∘F) during the warmest part of late summer, which is typical for a major Irish river. This low temperature range means the water remains cold enough throughout the year to pose a risk of cold shock to unprepared swimmers.
While the River Boyne is not designated as a bathing water area near Navan and official swimming is not encouraged due to currents, potential hazards like weirs, and water quality issues which can be subject to change, recreational activities are very popular. Locals and visitors often use the river for kayaking and angling, which are popular pursuits along the river's extensive stretches and towpaths, such as the Boyne Ramparts Walk. The Navan area is also a fantastic base for exploring the rich historical heritage of the Boyne Valley, including the ancient Neolithic tombs of Brú na Bóinne (Newgrange and Knowth) and the legendary Hill of Tara.
