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 Split are popular because of those long warm-season waters and a variety of coastal settings. The city has rocky and pebbly beaches directly accessible from the promenade and Marjan peninsula, where clear water and numerous small coves make swimming and snorkeling attractive when temperatures are above 20 °C from late May into October. Ferries and day trips to nearby islands such as Brač and Hvar open access to sandy spots and more sheltered bays that often feel warmer and calmer. For visitors seeking organized beach facilities, family-friendly swimming areas, or more secluded rocky coves, the sea temperatures in summer offer comfortable conditions for long swims, water sports, and regular beach activity.
