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 around Antonina is primarily experienced in sheltered bay areas and nearby coastal beaches, where calmer waters and gentler waves make for family-friendly bathing, especially in the warmer months when temperatures around 24 °C to 28 °C feel comfortable for prolonged swims. Cooler months with waters near 16 °C to 20 °C are less inviting for casual swimmers but still suitable for brisk dips and for swimmers equipped with wetsuits; spring and autumn offer a balance between comfortable conditions and fewer crowds.
