*** 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
In the Bartın area, surface temperatures of local lakes vary substantially through the year because of the temperate Black Sea climate. In winter months the water typically cools to around 2–6 °C (36–43 °F), though occasional cold snaps can push temperatures a degree or two lower. Spring brings a steady rise, with lakes commonly measuring 8–15 °C (46–59 °F) as air temperatures moderate. Peak summer surface temperatures are usually reached between July and August, often sitting in the 20–25 °C range (68–77 °F) on sunny days, which is warmest for recreational use. In autumn the waters cool again to roughly 10–16 °C (50–61 °F), transitioning back toward winter lows.
Swimming in Bartın’s lakes is seasonally dependent and generally most feasible in mid to late summer when surface temperatures exceed about 20 °C (68 °F). Outside that period, colder water increases the risk of hypothermia and makes prolonged swimming uncomfortable. Whether swimming is officially allowed depends on specific sites: some lakes and designated recreational areas permit swimming and have facilities or lifeguards, while others restrict access for conservation, water quality, or safety reasons. Visitors should check local signage and conditions, assess water clarity and currents, and follow regulations to ensure safe use of the lakes.
