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
Reni is a small port city in the far southwest of Odesa Oblast, located right on the bank of the Danube River, near the meeting point of Ukraine, Romania, and Moldova. In this section, the Danube is wide and slow-flowing, which allows the water to warm up fairly well during summer. From late May to early September, the water temperature usually stays between 21–26°C, and on especially hot days it can rise even higher, making short swims refreshing and comfortable.
However, swimming in the Danube at Reni is not without caution. The river here is part of a busy navigation route with occasional cargo and border patrol vessels, so swimming directly near the port or in shipping zones is unsafe and not allowed. Locals who swim usually choose calmer spots slightly away from the main current or near small inlets and sandy banks outside the urban area. The water quality varies — during high flow periods it can become muddy, but on quiet days it’s relatively clean and pleasant for bathing.
