Tide Table Portland — 2026

📘 About Portland Tide Forecast

Situated along the coastline of Australia (-38.35° S, 141.62° E), Portland lies in the southern hemisphere. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.7m and spring tides reaching up to 0.9m. With under 1.5m of variation, beaches maintain a relatively constant band of wet sand throughout the day. Sport fishers in mixed tide regions target the day's higher high tide when chasing predatory coastal fish. This coast is subject to longshore drift currents that distribute sediment and shape beaches throughout the year.
