What time is high tide, and when should I leave?
Shimbiri gives you the tide times and heights for your port or your position, with sunrise, sunset and twilight for where you are.
It then folds the tide into the passage, so the answer to “when should I leave?” already allows for the tide you need.
What it does
- Tide times and heights for Australian ports and for your position
- Tide curves, with high and low marked
- Tide gates for bars and channels on a route
- Sunrise, sunset and twilight for where you are
- Moon phase
The answer below is Shimbiri’s Captain on 26 September 2026, at anchor in Pittwater, asked for today’s tides, high water and sunset.
Seen at sea
Pittwater, 23 September 2026. Asked for the best time to leave that afternoon on a high tide, Shimbiri gave high water at 17:49, 1.46 m, and a departure window of 17:00 to 18:00 as the sea breeze died, with a note to check bar clearance on the chartplotter because the heights come from a tide model. At sea off the Victorian coast a week earlier, it gave sunrise at 06:02 for the boat’s own position. At anchor in Pittwater on 26 September, it gave high water at 19:48, 1.58 m, sunset at 17:53 and moonrise nearly full, said that the heights come from a tide model 4.1 nm away, and pointed out that the evening’s strong wind warning peaked at high water, when the anchor needs the most scope.
What you need
Works from a phone or PC. Tide and light at the boat’s own position come from the Chief Engineer pack aboard; otherwise pick a port.
