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)

Where this tide comes from
Blanche Harbor has no station of its own, so we use the tide at Whyalla (TICON-4), 24 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 Blanche Harbor
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.7 ft
- Highest expectedHighest1.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.4 ft. Before heading out, expect waves of up to 1.4 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 Monday 2: 2.6 ft with a period of 4 s, from the south-southwest (slight).
Water temperature
Water temperature →The satellite measured 3.2 °F less 2 days ago than the model gives now: the water is probably colder than the forecast says.
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 71.8 °F by Wednesday 4.
Water warmer than normal for late October (+4.4 °F).

Moon phase and position
Today the moon is 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:20–4:20 am Major · the moon passes overhead · high activity
- 2:52–4:52 pm Major · the moon passes underfoot · high activity
- 7:44–8:44 am Minor · moonset · medium activity
- 11:02 pm–12:02 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.
