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
Chiwan has no station of its own, so we use the tide at Hong Kong (TICON-4), 25 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 Chiwan
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
Cross-onshore wind. The coast faces southwest and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Saturday 31: 1.3 ft with a period of 3 s, from the east-southeast (smooth).
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.

Your diving day at a glance
The best window, 11:30 am to 2:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high.
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 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:29–3:29 am Major · the moon passes overhead · high activity
- 2:02–4:02 pm Major · the moon passes underfoot · high activity
- 9:06–10:06 am Minor · moonset · medium activity
- 7:56–8:56 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.
