Hobart, Tasmania tide times

The hero block shows the next high tide on the lower Derwent at Hobart in local Tasmanian time (AEST in winter, AEDT in summer — Tasmania runs the same DST schedule as the eastern Australian mainland). The 7-day table covers all four daily extremes. High water at New Norfolk on the upper Derwent lags Hobart by about 30 minutes.

Mean range on the lower Derwent at Hobart is about 1.0 metre, modest by Australian standards. Spring tides push close to 1.4 metres around new and full moons; neaps drop close to 0.6 metres. The north Tasmanian coast at Devonport and Burnie runs notably larger swings — close to 2.5 metres on springs — because Bass Strait amplifies the open Tasman Sea signal.

Bass Strait, the body of water between Tasmania and the Australian mainland, behaves as a partially-closed shallow channel that amplifies the open Tasman Sea tide as it propagates through. Devonport, Burnie, and the broader north-coast gauges all see ranges roughly twice the Hobart swing. The west coast at Strahan and the south-east coast at Hobart both sit on the open-ocean side of the island and run smaller, more typical Tasman Sea patterns.

Open-Meteo Marine, a gridded global ocean model. Useful for daily planning around the Derwent and Storm Bay. For authoritative Tasmanian tide data, the Australian Bureau of Meteorology operates the official gauge network at Hobart, Devonport, Burnie, and Spring Bay, and Maritime Safety Tasmania publishes specific guidance for the wild west coast and the Hells Gates entrance to Macquarie Harbour.

No. For piloting in or out of Hobart, transiting Storm Bay, or working the Tasman Peninsula sea cliffs and the wild west coast use BoM's authoritative tide tables, the Australian Hydrographic Office chart products, and the latest Maritime Safety Tasmania notices. The Hells Gates bar entry to Macquarie Harbour on the west coast runs hard on the change of tide and breaking seas there are a working hazard, not a planning matter.
