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 Jirkov, the Bílina River flows quietly through the edge of the town, but it is not known as a place for recreational swimming. The river here is relatively narrow and often influenced by its industrial surroundings, which means that the water quality can vary and is not always ideal for safe bathing. During summer months, the water temperature typically follows the warm air, often rising into the low 20s °C, but this does not necessarily make the river inviting for swimmers.
Most locals and visitors do not use the Bílina in Jirkov for swimming. Instead, the river is more commonly enjoyed for short walks along its banks or as part of the natural landscape that frames the town. Those seeking a refreshing dip usually head to nearby ponds, lakes, or official swimming areas where water quality is monitored. As a result, while the Bílina contributes to the atmosphere of Jirkov, it is not considered a practical spot for bathing.
