*** 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.
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
Orkney, an archipelago off the northeastern coast of Scotland, experiences cool sea temperatures year-round due to its northern North Atlantic location and strong maritime influences. Sea surface temperatures typically fall to around 4–7 °C in the coldest months of winter, rise through spring to roughly 6–9 °C, and reach their warmest in late summer when coastal waters are commonly between 11–14 °C. Autumn temperatures generally cool back to around 8–10 °C. Local conditions vary with exposure, tides and currents: sheltered bays and shallow inlets warm slightly more than open, exposed shores, while strong currents and frequent winds can make the felt temperature lower than the measured water temperature.

Swimming Conditions
Swimming around Orkney appeals to people seeking wild, coastal experiences rather than traditional warm beach holidays. Summer dips are possible and invigorating, with many swimmers and sea swimmers using wetsuits even in the warmest months to extend time in the water and reduce risk of cold shock. Several sandy bays and sheltered coves provide accessible entry points, and calmer days allow comfortable short swims and snorkeling. However, swimmers should be aware of sudden weather changes, tidal streams, and cold-water conditions; local advice, appropriate gear such as wetsuits or drysuits, and informed entry and exit plans are recommended. For those prepared for cooler waters, Orkney offers dramatic scenery and a unique shoreline for bathing and wild-swimming experiences.
