↑ Rising The tide is rising. 4 h 3 min to high tide at 3:54 pm.
Tide coefficient 95 for the 3:50 am high tide and 90 for the 3:54 pm high tide. Spring tides. The water rises and falls 4.8 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 (6.0 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 12 to 13 (coefficient 109, 4.8 ft range). The smallest, on October 20 (coefficient 20, 1.9 ft).

Where this tide comes from
Tumby Bay has no station of its own, so we use the tide at Port Lincoln (TICON-4), 27 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at Tumby Bay
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant2.0 ft
- Highest expectedHighest4.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.1 ft. Before heading out, expect waves of up to 4.1 ft.
Wind on the coast and offshore
Onshore wind. The coast faces east and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Wednesday 4: 3.8 ft with a period of 5 s, from the south-southwest (slight).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 67.7 °F by Wednesday 4.
Water warmer than normal for late October (+4.2 °F).

- Tide: high 3:50 am (5.5 ft), low 10:56 am (0.7 ft), high 3:54 pm (2.2 ft) and low 9:03 pm (0.6 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.

Today’s surf at a glance
The best window is 6:01 am to 10:00 am, though with small waves, a short-period swell, wind swell and onshore wind.
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.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance
The best window, 2:30 pm to 4:50 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also worth a look from 10:30 am to 11:20 am, with slack water at low tide, little swell, weak current and the sun high, though with moderate wind.
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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:27–4:27 am Major · the moon passes overhead · high activity
- 2:59–4:59 pm Major · the moon passes underfoot · high activity
- 7:46–8:46 am Minor · moonset · medium activity
- 11:14 pm–12:14 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 2.5 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).
