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
Kostopil, located in Rivne Oblast, is crossed by the small Zamchys’ko River, which flows quietly through the town’s green areas and outskirts. The river is shallow and narrow, so during summer it warms up quickly — temperatures often range between 21 and 25°C. Because of its modest size and slow current, the water feels pleasantly mild on hot days, though after rains it can become slightly muddy. In dry and sunny periods, the river stays clean and clear enough for brief swimming or wading.
Swimming in the Zamchys’ko within Kostopil is limited but possible in several natural spots where the banks are low and the water a bit deeper. Locals, especially children and young people, often cool off there in summer. It’s not a large or developed recreational river, but it offers a quiet, natural setting for a refreshing dip. For residents of Kostopil, the Zamchys’ko remains more of a peaceful local retreat than a formal swimming place.
