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
Hatvan lies on the banks of the Zagyva River, which flows quietly through the city. While the river adds a natural charm to the town, it is not considered a safe or popular place for swimming. In the summer, the Zagyva’s water temperature can rise to about 20–22°C, but the river is relatively shallow with a changing flow, and water quality is not always reliable. Because of this, locals generally avoid bathing in it, and it serves more as a scenic feature than a recreational one.
For those looking to swim in Hatvan, the focus is on managed facilities such as pools and nearby lakes, where the conditions are cleaner and more suitable for bathing. In summer, outdoor pools typically warm up to 24–27°C, offering a more comfortable and safe experience than the river itself. As a result, the Zagyva enriches the landscape of Hatvan, while swimming opportunities are centered on organized water complexes.
