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
#Northumberland
Little Swinburne Reservoir is a small upland water body in Northumberland whose surface temperatures are typically cool year-round. In winter the water often sits around 4–6 °C (39–43 °F), rising through spring to roughly 6–12 °C (43–54 °F). In summer surface temperatures may reach approximately 12–18 °C (54–64 °F) on warm days, while autumn sees a steady decline back to single figures, about 8–12 °C (46–54 °F). These figures are approximate and can vary with weather, depth and inflow, so the reservoir usually feels colder than lowland lakes at the same time of year.
Swimming at Little Swinburne is generally not recommended and is often restricted because the reservoir functions as a drinking-water supply with steep banks, cold deep water and underwater hazards that pose safety and water-quality concerns. Visitors commonly use the surrounding area for walking, birdwatching and photography instead. Nearby attractions include the Coquet Valley landscape and upland walking routes such as the Simonside Hills, with market towns like Rothbury offering local amenities a short drive away.
