*** 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.

Swimming Conditions
Swimming and beach holidays in the Rustington area suit visitors prepared for cooler British coastal waters rather than warm Mediterranean bathing. The immediate shoreline is a mix of shingle and small patches of sand, with more sheltered sandy stretches and family-friendly beaches a short drive away. Popular summer months offer the most comfortable bathing conditions and some nearby beaches are lifeguarded during the main season; water-based activities such as paddleboarding, kayaking and shoreline swimming are common. Many swimmers use wetsuits outside the peak weeks, especially in spring and autumn. Visitors should be aware of changing tides and occasional currents, observe local safety signage and check for lifeguard coverage before entering the water. Onshore facilities, cafes and accommodation make Rustington a convenient base for a modest beach holiday focused on coastal walks and active, seasonal water recreation.
