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.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Omiš sits where the Cetina river meets the Adriatic, creating a coastal town with clear water and varied local conditions. Sea surface temperatures off Omiš follow the typical Dalmatian pattern: in winter (December–February) waters average around 13–16 °C, spring (March–May) warms from roughly 15 up to 20 °C, and summer (June–August) brings the warmest readings typically between 22 and 26 °C, with August often the peak month. Autumn (September–November) sees a gradual cooling, with sea temperatures commonly ranging from 18 to 23 °C. Close to the river mouth temperatures can be slightly lower, particularly after heavy runoff or in cooler months, so short-term local variation is normal.

Swimming Conditions
Swimming and beach opportunities in and around Omiš are good for a range of visitors, from families to active water-sport enthusiasts. The town offers pebble and small sandy stretches with convenient access to the sea, sheltered bays that warm quickly in summer, and rocky headlands popular for snorkeling and jumping. Boat trips and coastal swims reveal clear water and good visibility in summer when sea temperatures are typically 22–26 °C.
