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.

Location & Local Information
The Sutla River, also known as Sotla in Slovenia, forms part of the natural border between Slovenia and Croatia. It flows through a mostly hilly and rural landscape, with a calm character in many sections. Being a lowland river, its water warms up more quickly in summer than alpine streams, often reaching pleasantly mild temperatures during hot weather. After heavy rains, however, the river can cool down and its flow may become stronger.
Swimming in the Sutla is possible in some calmer stretches, though it is not a typical recreational river. The depth varies, and in many areas the river is shallow or has muddy banks, making it less convenient for bathing. Locals may sometimes cool off in deeper pools or quieter bends of the river, but overall it is better suited for brief refreshment and relaxation by the water rather than organized swimming.
