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 Altea benefit from a variety of shore types and generally clear Mediterranean water. The main beaches and nearby coves offer gentle entry for family swimming when waters are above 20 °C in late spring and summer, while rocky stretches and underwater cliffs provide good opportunities for snorkeling and casual diving when visibility is high. Sheltered bays can make for calmer swims and paddle sports, and promenades, local services and seasonal lifeguards support beachgoing in peak months. Visitors seeking warm-water swimming should plan for the summer months, though fit or acclimatised swimmers may enjoy cool, quieter swims outside the high season.
