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.

Swimming Conditions
Swimming at Shelly Beach suits a wide range of visitors, from families seeking gentle paddles to more confident swimmers and surfers enjoying larger swells. The main sandy stretch is patrolled during peak holiday periods and marked swimming zones should be used for safest conditions; tidal pools and sheltered bays offer calmer options on rough days. Rip currents can occur, particularly after storms or along channels, so awareness of flag systems and local advice is important. Water quality is generally good but can be impacted by heavy rain runoff. Because water temperatures are relatively mild, wetsuits are rarely required for casual beach swimming, though some swimmers prefer light thermal wear during the coolest months for longer sessions.
