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.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Salthill sits on the shores of Galway Bay in the west of Ireland, where the coastal waters are cool year-round and influenced by Atlantic currents and tidal flows. Typical seasonal water temperatures in the area vary from around 8–10 °C in winter (December–February), rising through spring to roughly 9–12 °C (March–May). Summer months (June–August) bring the warmest conditions, with surface temperatures commonly between 13–16 °C on milder days, and early autumn (September–November) generally cooling to about 11–14 °C. Shallow and sheltered spots near the promenade can feel slightly warmer in calm weather, while open stretches and deeper channels remain colder. Short-term variations occur with weather, sea state and tidal movements, so actual readings can differ from these averages.
