Today's high and low tides
- ▼ Low tide 4:36 am 1.1 ft
- ▲ High tide 11:13 am 5.9 ft · coef. 88
- ▼ Next low tide 5:54 pm 0.6 ft
- ▲ High tide 11:58 pm 4.1 ft · coef. 83
↓ Falling The tide is falling. 3 h 21 min to low tide at 5:54 pm.
Tide coefficient 88 for the 11:13 am high tide and 83 for the 11:58 pm high tide. Average coefficient. The water rises and falls 5.3 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 June 16 (6.6 ft) and the lowest, on December 25 (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 26 to 28 (coefficient 95, 5.4 ft range). The smallest, from October 18 to 19 (coefficient 37, 2.8 ft).

Where this tide comes from
Salamander Bay has no station of its own, so we use the tide at Newcastle (TICON-4), 22 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 Salamander Bay
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.2 ft
- Significant4.5 ft
- Highest expectedHighest8.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.9 ft. Before heading out, expect waves of up to 8.9 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northeast and the wind comes off the land at an angle: calmer water near the shore, and bait and boats drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Friday 30: 5.2 ft with a period of 11 s, from the south (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water is steady these days, with no sudden changes.

- Likely visibility: good. Swell (up to 3.8 ft at 8 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 66.9–68.4 °F: a 5 mm wetsuit.

- Night dive: dark from 7:41 pm. Waning gibbous (89%), rising at 11:02 pm: a bright night.
Your diving day at a glance
The best window, 10:20 am to 11:30 am, combines slack water at high tide, light wind, weak current and the sun high, though with some swell.
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.

The moon in Salamander Bay
Moon phase and position
Today the moon is 226,459 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:50–3:50 am Major · the moon passes overhead · high activity
- 2:22–4:22 pm Major · the moon passes underfoot · high activity
- 7:15–8:15 am Minor · moonset · medium activity
- 10:32–11:32 pm 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.
