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
Český Krumlov is a picturesque town in the South Bohemian Region of the Czech Republic, famous for its historic center and castle. The Vltava River flows right through the town, winding gently around its medieval streets. In the area of Český Krumlov, the river is relatively calm in some sections, and during the summer months, especially July and August, water temperatures typically reach around 20–23 °C. This makes swimming possible, though the river here is more often enjoyed for canoeing, kayaking, or riverside relaxation rather than extensive bathing.
Swimming in Český Krumlov itself tends to be informal and limited to quieter spots away from the town’s main tourist areas. The riverbanks can be steep in places, so finding safe entry points is important. Locals and adventurous visitors sometimes take short dips in the Vltava, combining it with a break from sightseeing or a picnic along the river. The calm sections of the river near the town outskirts are generally the safest for this kind of activity.
Outside the peak summer months, water temperatures drop noticeably. In May or September, the Vltava near Český Krumlov usually stays around 15–17 °C, which is cool for swimming but still suitable for brief wading or simply enjoying the riverside scenery. Even when the water is too cold to swim, the river adds a beautiful natural element to the town, making it perfect for relaxing walks, photography, and soaking in the charm of the historic landscape.
