Opatija tide times

Mean tidal range at Opatija is approximately 0.6–0.7 m, elevated above the southern Adriatic norm because of Kvarner Gulf amplification. Spring ranges can reach 0.9 m. Tides are semidiurnal — two high and two low waters per day. The Croatian Hydrographic Institute (HHI) publishes official tables; this site uses Open-Meteo Marine model data (±45 min, ±0.2–0.3 m). Tidal state is relevant at Opatija: most bathing platforms are noticeably more comfortable around high water.

The Lungomare (officially Šetalište Franz Josef I.) is a 12-km promenade running from Volosko north of Opatija south through the town centre and on to Lovran. Built in 1889 during the Habsburg resort era, it hugs the rocky coastline at sea level, passing hotel gardens, bathing coves, and a series of small beaches. The path is flat, well-maintained, and usable year-round. It is one of the Kvarner coast's signature walks — tidal variation of 0.6–0.7 m means the seaward edge of the path is occasionally wave-washed at high spring tides combined with scirocco swell.

High tide gives the most water above the stabilised rock bathing platforms (riva) and reduces exposure to slippery kelp-covered lower rocks. With a tidal range of 0.6–0.7 m, the difference in water depth at a platform edge between high and low tide is around half a metre — enough to make entry and exit noticeably easier at high water. In summer, water temperature peaks around 24–25 °C in August. The coast faces west and is sheltered from northeast bura by the Učka massif; southwesterly scirocco swells in autumn can make the riva rough for 12–24 hours.

Opatija sits at the northern end of the Kvarner, close to Rijeka's commercial port and within day-sail range of Krk, Cres, and Lošinj. Marina Opatija is small (around 80 berths); ACI Marina Opatija has more capacity. The bura wind, accelerating through the Rijeka channel from the northeast, can build fast — a shift from Force 3 to Force 8 in 30 minutes is documented in local logs. Opatija's position in the lee of Učka offers some protection from northeast bura compared to more exposed anchorages further south in the Kvarner.

These predictions are for general information only and not a substitute for official navigation data. Open-Meteo Marine model output carries ±45 min timing uncertainty and ±0.2–0.3 m height uncertainty. For any draft-sensitive manoeuvre or harbour entry, verify against official HHI tide tables and check real-time DHMZ forecasts for bura and scirocco events, which can shift actual water levels significantly away from tidal predictions.
