*** Forecast - Our water temperature forecast
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
The Voynishka River (Войнишка) typically shows marked seasonal variation in water temperature because it is a relatively small, often shaded watercourse influenced by rainfall, snowmelt and local topography. In winter months temperatures commonly hover near freezing, roughly 0–4 °C (32–39 °F), while spring brings gradual warming as snowmelt and higher air temperatures raise the flow to about 5–12 °C (41–54 °F). In summer, the warmest period, slower, pooled sections can reach approximately 15–22 °C (59–72 °F), though faster or deeper stretches remain noticeably cooler. Autumn cooling is gradual, with temperatures typically falling to the range of 8–14 °C (46–57 °F). Local microclimates, sun exposure and recent weather can shift these values up or down by a few degrees.
Swimming in the Voynishka is possible in many accessible, calmer stretches, but it is not universally recommended without checking local conditions. There are no blanket national bans on swimming in most rural Bulgarian rivers, yet safety and water quality concerns—strong currents after rain, hidden rocks, cold temperatures outside midsummer, and occasional restrictions in protected or managed areas—can make particular spots unsafe. Visitors should look for posted signs, heed local advice, avoid swimming after heavy rains, and be aware that even in summer the water can remain cool enough to cause cold-water shock for unprepared swimmers.
