*** 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 Sfântu Gheorghe branch (Brațul Sfântu Gheorghe) of the Danube in south‑east Romania shows clear seasonal variation in water temperature. In winter the water typically hovers around 0–4 °C (32–39 °F), while spring brings gradual warming to roughly 6–15 °C (43–59 °F). Summer is when the branch is warmest, commonly between about 20–26 °C (68–79 °F) and occasionally reaching near 28 °C (82 °F) in shallow, sheltered stretches. During autumn temperatures usually fall back to roughly 10–18 °C (50–64 °F) as the river cools ahead of winter. Local microclimates, water depth and river flow influence exact values, so temperatures can vary along different parts of the channel.
Swimming in the Sfântu Gheorghe branch is physically possible and is most commonly undertaken in the warm summer months when temperatures are comfortable, but it is not universally advisable. Safety concerns include boat traffic and currents in the main channel, variable water quality after rains or floods, and regulations linked to the Danube Delta’s protected status that can limit access in sensitive zones. For these reasons many people only swim in quieter side arms or designated spots, and it is sensible to follow local signage, heed authority guidance and take standard precautions such as avoiding swimming alone and after heavy rainfall.
