*** 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
Gorizia sits on the Isonzo River in Friuli‑Venezia Giulia and is close to several lakes and reservoirs in the broader region. Surface water temperatures in local lakes and the river vary markedly with the seasons: in winter they commonly fall to about 2–6 °C (36–43 °F), spring sees a rise to roughly 8–15 °C (46–59 °F), summer brings the warmest conditions with typical ranges around 20–26 °C (68–79 °F), and autumn cools back to approximately 12–18 °C (54–64 °F). Mountain-fed streams and some karstic basins remain colder year‑round, while shallower, sheltered lakes warm fastest in late summer.
Swimming is generally permitted in lakes and in designated river spots around Gorizia, especially during the summer bathing season when authorities monitor water quality. However, access is often limited to marked bathing areas for safety and environmental protection; strong currents, sudden depth changes and low temperatures outside summer can make unsupervised swimming risky. Local municipalities and regional environmental agencies publish advisories and test results, so swimmers are advised to use official beaches or supervised sites and heed posted warnings to ensure both legal compliance and personal safety.
