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
Carbis Bay is a sheltered sandy cove on the north coast of Cornwall, England, just south of St Ives. The bay’s curved shape and sandbanks often produce gentler seas than nearby exposed headlands, though it remains influenced by the Atlantic swell. Seasonal surface water temperatures are typically cool: in winter (December–February) the sea is about 8–10 °C, in spring (March–May) it generally rises to around 9–12 °C, summer (June–August) brings the warmest conditions at roughly 13–17 °C, and autumn (September–November) usually sees temperatures of approximately 11–14 °C. Short-term variation occurs with weather, tides and sunshine, and shallow, sunlit areas can warm slightly on prolonged warm spells.

Swimming Conditions
Swimming at Carbis Bay is popular for families, casual paddlers and open-water enthusiasts, but should be approached with the water temperatures in mind. The gently shelving sand offers easy entry and makes the beach suitable for children and less confident swimmers, while the relatively calm bay is well suited to kayaking and stand-up paddleboarding. Because even summer water remains cool, many swimmers and triathletes prefer wetsuits for longer sessions; short dips and paddling are common for holiday visitors. As with any coastal spot, swimmers should heed local safety advice, watch for changing tides and weather, and select clothing and equipment appropriate to the temperature ranges above.
