Where this tide comes from
Guantou has no station of its own, so we use the tide at Matsu (CWA), 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 Guantou
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.1 ft
- Highest expectedHighest2.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.3 ft. Before heading out, expect waves of up to 2.3 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces southeast 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 Monday 2: 2.5 ft with a period of 5 s, from the east-northeast (slight).
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, 11:00 am to 1:20 pm, combines slack water at high tide, small waves, light wind, weak current and the sun high. Also good from 5:40 am to 7:00 am, with slack water at low tide, small waves, light wind and weak current. Also worth a look from 4:40 pm to 5:20 pm, with small waves, light wind and weak current, though with tidal 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.
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- 1:06–3:06 am Major · the moon passes overhead · high activity
- 1:38–3:38 pm Major · the moon passes underfoot · high activity
- 8:52–9:52 am Minor · moonset · medium activity
- 7:22–8:22 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.
