*** 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 Ramor, located near Virginia in County Cavan, is a large, shallow lake that forms part of the upper River Blackwater system. Its water temperature changes gently with the seasons, averaging around 4–6°C (39–43°F) in winter and warming to about 15–18°C (59–64°F) in summer. On particularly sunny days, shallow bays can briefly reach 19°C (66°F), though cooler currents remain beneath the surface. Because of its relatively shallow depth, the lake warms a little faster than deeper western lakes, making it suitable for swimming during late spring and summer. The most comfortable swimming period is usually from June through early September, when both air and water temperatures are at their mildest.
Swimming is allowed in Lough Ramor, and it is popular among locals and visitors seeking calm, open-water conditions. Designated access points near Virginia are considered safe for swimming, and wetsuits are often worn outside the warmest weeks. The lake’s clean water also supports boating, paddleboarding, and fishing, adding to its recreational appeal. Beyond swimming, the surrounding area offers woodland walks, picnic spots, and views of the Cavan countryside. The nearby town of Virginia provides accommodation and dining options, making Lough Ramor a pleasant destination for both outdoor activity and quiet relaxation.
