Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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.

The River Tweed, famous for its salmon fishing and course through the Scottish Borders, maintains a consistently cool temperature reflective of its northern latitude. Throughout the year, water temperatures typically range from a chilling 4∘C (39∘F) in the depths of winter to a milder, yet still cool, 17∘C (63∘F) during the warmest summer months. Even at its peak, the water temperature is often considered cold for casual bathing, usually necessitating a wetsuit for longer periods of immersion.
While the River Tweed is a prominent destination for wild swimming, particularly around beauty spots like Peebles and sections near the coast, it is crucial to approach the activity with caution. There are no official lifeguards and the river is non-tidal for the majority of its length, but it features strong currents, deep pools, and hazards like weirs and submerged debris. Swimmers are encouraged to research local spots, never swim alone, and check for any temporary warnings related to water quality, which can occasionally be an issue. Beyond the river, visitors can explore historic sites such as Neidpath Castle and Abbotsford, the former home of Sir Walter Scott.
