*** 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
Maumwee Lough lies just north of Maam Cross in County Galway, nestled in the Connemara countryside and part of the Corrib catchment. While no detailed long-term temperature dataset is publicly available for the lake, its modest size and typical conditions allow a reasoned estimate of its annual range. In winter the surface waters likely hover around 4–6 °C (39–43 °F), given the cool Atlantic-influenced climate and year-round fresh inflows. By midsummer, shallow edges may rise to about 14–17 °C (57–63 °F) and on particularly calm, sunny days perhaps even briefly touch 18 °C (64 °F). Its relatively small area and depth allow a bit more warming than some larger lakes, but the water remains fresh and cool at all times.
Swimming in Maumwee Lough is possible, but with caveats. Because the lake is small and less developed for recreation, swimmers should use caution—and perhaps favour short dips during the warmest months of July and August when surface temperatures are at their most inviting. Wetsuits may be wise outside those peak weeks. Access to gentle shorelines near Maam Cross offers the safest entries, but the terrain can be uneven and the lake less supervised. Nearby, the Connemara landscape provides a rich backdrop: historic Maumturk Mountains, quiet trails, and riverside walks offer a mix of outdoor recreation beyond the water itself. For those comfortable with cool-water swimming and well-aware of conditions, Maumwee Lough offers a peaceful, scenic spot in western Ireland.
