Mixed: two high and two low tides a day, but of quite different heights.

Where this tide comes from
Penneshaw has no station of its own, so we use the tide at Cape Jervis (TICON-4), 12 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 waves you may find
- Most commonMost common0.5 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.1 ft. Before heading out, expect waves of up to 2.1 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.

Waves build over the next few days. The biggest waves arrive on Saturday 31: 2.8 ft with a period of 4 s, from the west-northwest (slight).
Water temperature

Your diving day at a glance
The best window, 12:10 pm to 3:00 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 6:00 pm to 7:30 pm, with slack water at high tide, little swell, light wind and weak 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.

Moon phase and position
Today the moon is 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:19–4:19 am Major · the moon passes overhead · high activity
- 2:51–4:51 pm Major · the moon passes underfoot · high activity
- 7:34–8:34 am Minor · moonset · medium activity
- 11:11 pm–12:11 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.

Water depth
Deepens quicklyThe bottom deepens quickly: 33 ft of water 950 ft from shore.

How far from shore
- 16 ft deep390 ft
- 33 ft deep950 ft
- 66 ft deep2.7 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 13 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. 33 ft deep 950 ft from shore; 66 ft is far out (2.7 mi): for deeper dives, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
Source: NOAA ETOPO 2022 (CC0), cells of about 0.3 mi; depth below mean sea level. For reference only: not for navigation or anchoring.
