Water Temperature: Daily Trends, Historical Records, and Forecast
⚠️ As of today, the minimum water temperature ranges from 60°F (15°C) to 65°F (18°C). The water is comfortable for most people, making it an ideal range for water sports enthusiasts. The temperature does not cause significant discomfort, and swimming will be pleasant for the majority. However, it's important to remember that prolonged exposure to the water can still lead to cooling, so it's essential to monitor the time spent in the water, especially for children or elderly people. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

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.

The Yeşilırmak Nehri (Yeşilırmak) runs through Samsun province to the Black Sea and shows marked seasonal shifts in water temperature. In winter the river commonly cools to roughly 4–8 °C (39–46 °F), spring warming moves temperatures into the neighborhood of 8–15 °C (46–59 °F), summer surface temperatures in calmer stretches often reach about 18–24 °C (64–75 °F), and autumn sees cooling to approximately 10–16 °C (50–61 °F). These figures vary with depth, flow rate, recent precipitation and upstream snowmelt; shallower and slower side channels heat more in summer, while fast main-channel currents stay cooler.
Swimming opportunities on the Yeşilırmak in and around Samsun are limited and conditional. In urban and lower reaches swimming is generally not recommended because of variable water quality, agricultural and municipal runoff, strong currents in places, and boat traffic; local regulations or signage may prohibit bathing for safety and public-health reasons. In upstream or sheltered backwater areas, where water is clearer and flow is gentler, locals sometimes swim during the warmest months when temperatures approach the higher summer range. Anyone considering swimming should check current water-quality reports, heed local rules, and be cautious about currents and underwater hazards.
