*** 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
Lake Arin (Arin Gölü) in Bitlis is a highland freshwater lake whose surface temperatures reflect the cool eastern Anatolian climate. Seasonal surface temperatures typically range from near freezing in winter—about 0 to 4 °C (32 to 39 °F)—to modestly temperate in summer, roughly 15 to 22 °C (59 to 72 °F). Spring and autumn are transitional, with water commonly between 4 and 12 °C (39 to 54 °F) in spring and 8 to 14 °C (46 to 57 °F) in autumn. These values vary with year-to-year weather, wind, depth and sunlight; shallower bays warm fastest in summer, while deeper areas remain noticeably cooler.
Swimming is technically possible during the brief warm season but is not widespread: the lake’s summer surface temperatures are only comfortably water-swimmable for some swimmers, while spring, autumn and winter are generally too cold for safe, comfortable recreational swimming. In addition to low temperatures, limited infrastructure, remote access and occasional conservation or local-use restrictions make swimming uncommon. For anyone considering entering the water, the main considerations are cold-shock risk, limited rescue resources and respect for any local protections, so many visitors opt for short dips only during the warmest weeks or choose alternative activities.
