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
In Znojmo, the river Thaya flows through a deep valley just below the historic old town, giving the city a unique riverside atmosphere. The water here tends to be cooler compared to lowland stretches, with summer temperatures often ranging between 16°C and 21°C depending on recent weather. The shaded cliffs and forested slopes along the river mean that the water does not warm up as quickly as in open countryside, so swimming here feels refreshing, especially on hot July and August days.
Swimming in the Thaya at Znojmo is possible, though it is less of a structured beach environment and more of a natural riverside experience. Locals and visitors sometimes find quiet spots along the banks where access is easier, but currents can vary, and the riverbed is stony in places. Many people prefer wading, cooling off, or using the river for short swims rather than extended bathing. The combination of cooler water, dramatic scenery, and relative tranquility makes a dip in the Thaya near Znojmo memorable, especially if you enjoy natural swimming rather than developed bathing areas.
