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
Port William sits on the sheltered shore of Luce Bay in the Machars peninsula of south-west Scotland, facing the Irish Sea. The coastal waters here are noticeably cool year-round compared with southerly bathing spots. Typical seasonal surface temperatures are about 5–8 °C in winter, 7–12 °C in spring, 12–16 °C in summer, and 9–13 °C in autumn; late summer often gives the warmest readings, while prolonged onshore winds or northerly weather can depress temperatures quickly. Because the bay is relatively shallow and open to tidal flows, local conditions can vary from day to day, with clearer, warmer water on calm, sunny stretches and colder, more turbulent water when winds or tides are strong.

Swimming Conditions
Swimming and beach holidays at Port William are shaped by those cool temperatures and the village’s low-key character. The sandy beaches and gentle slopes make for pleasant paddling and family days out in settled weather, and open-water swimmers frequently use wetsuits to extend the season into spring and autumn. Lifeguard provision is limited, so visitors should check local advice on tides and sea conditions before entering the water; currents and sudden changes in temperature are the main risks. Beyond bathing, the area offers good opportunities for sea kayaking, coastal walks and wildlife watching, and the village provides basic amenities and accommodation for a quiet beach-based break where waters are best enjoyed with appropriate clothing and caution.
