*** Forecast - Our water temperature forecast
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 city of Celje lies along the Savinja River in central Slovenia, where the river flows through urban and park areas. In this part of the river, the water tends to be warmer than in the upper alpine stretches, especially during summer. From June to August, surface temperatures near Celje usually reach 20–24°C in slower, shallower sections, which can make swimming refreshing on hot days. In spring and autumn, the water is cooler, typically around 12–16°C, and in winter it drops to 4–6°C.
Swimming directly in the Savinja within Celje is limited due to urban infrastructure and varying currents. Some calmer, shallow areas near green spaces or riverbanks can be used for a quick dip, though swimming is mostly informal and at one’s own risk. Locals often prefer the river for relaxing by the water, wading, or paddling rather than full swimming.
During the warmer months, the river near Celje becomes a popular spot for enjoying the natural setting within the city. Outside summer, swimming is uncommon because of lower water temperatures, but the riverbanks remain attractive for walking, cycling, or picnicking. Even a short dip in summer can provide a refreshing break from the heat.
