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
Ostrov, located in the Karlovy Vary Region at the foot of the Ore Mountains, is surrounded by small ponds and streams that reflect the cooler climate of this part of the Czech Republic. Because of the higher elevation and forested surroundings, water in local ponds usually warms up more slowly than in lowland areas. In June, temperatures often range between 17–19 °C, while in July and August they can rise to 21–23 °C, with the warmest stretches of summer occasionally bringing the water close to 24 °C. Even so, the nights here are often cool, which keeps the water fresh and never too hot.
Swimming opportunities around Ostrov are mainly tied to these smaller ponds and natural spots along streams. Locals often use them for casual bathing during warm days, enjoying the quieter and more natural setting compared to larger reservoirs. Access is usually simple, with grassy banks or small clearings by the water, making it easy to take a refreshing dip. For visitors, the experience is less about long hours on a beach and more about short swims in pleasantly cool waters surrounded by greenery and calm landscapes.
