Today's high and low tides
- ▲ High tide 6:25 am 8.4 ft · coef. 88
- ▼ Next low tide 1:12 pm 0.8 ft
- ▲ High tide 6:50 pm 5.2 ft · coef. 85
↓ Falling The tide is falling. 4 h 48 min to low tide at 1:12 pm.
Tide coefficient 88 for the 6:25 am high tide and 85 for the 6:50 pm high tide. Average coefficient. The water rises and falls 7.6 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on May 18 (8.9 ft) and the lowest, on February 18 (0.1 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above chart datum: the lowest astronomical tide (LAT), the zero of nautical charts in Europe. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. chart datum (LAT)
Tide coefficient and range in October
The biggest tides of the month came from October 25 to 27 (coefficient 100, 8.2 ft range). The smallest, on October 20 (coefficient 25, 2.5 ft).

The sea at Taperoo
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.4 ft
- Significant0.9 ft
- Highest expectedHighest1.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.7 ft. Before heading out, expect waves of up to 1.7 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Offshore wind. The coast faces west and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.

Waves build over the next few days. The biggest waves arrive on Wednesday 4: 3.1 ft with a period of 5 s, from the southwest (slight).
Water temperature

Surf in Taperoo today
Surf today
Poor- 0.7–1.0 ft surf at the shore, small: good for learning or a longboard
- 0.6 ft swell at 9 s from the southwest, a bit short
- Light offshore wind (5 mph): it holds up and grooms the waves
- Falling tide (low tide at 1:12 pm)
- Light: First light 5:51 am · sunrise 6:18 am · sunset 7:42 pm · last light 8:09 pm
- Tide: high 6:25 am (8.4 ft), low 1:12 pm (0.8 ft) and high 6:50 pm (5.2 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 65.7 °F–66.6 °F: a 3/2 fullsuit.
- Energy: 5 kJ · Low power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has light offshore wind, though with small waves. 12:00 pm to 4:00 pm can also work, though with small waves.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Your diving day at a glance
The best window, 5:50 pm to 7:40 pm, combines slack water at high tide, little swell, light wind and weak current. Also worth a look from 12:10 pm to 1:50 pm, with slack water at low tide, little swell, light wind and the sun high, though with current.
Slack water comes from the tide: in inlets, channels and between islands the water can keep running for an hour or two after. Ask the local dive shop.

The moon in Taperoo
Moon phase and position
Today the moon is 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:17–4:17 am Major · the moon passes overhead · high activity
- 2:49–4:49 pm Major · the moon passes underfoot · high activity
- 7:34–8:34 am Minor · moonset · medium activity
- 11:06 pm–12:06 am Minor · moonrise · medium activity
According to solunar theory, fish feed more when the moon passes overhead or underfoot (major periods, about 2 h) and when it rises or sets (minor periods, 1 h). It works best around new and full moon.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
