Mixed: two high and two low tides a day, but of quite different heights.
Heights above chart datum (CD), the zero of that port's nautical charts. 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 (CD)

Where this tide comes from

The sea at Jinhu
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.1 ft
- Significant2.1 ft
- Highest expectedHighest4.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.5 ft. Before heading out, expect waves of up to 4.5 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-onshore wind. The coast faces southeast 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: 4.1 ft with a period of 5 s, from the east-northeast (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.

Surf in Jinhu today
Surf today
Poor- 1.2–1.9 ft surf at the shore, small: good for learning or a longboard
- 2.2 ft swell at 5 s from the east-northeast, short: weak, messy waves
- Moderate offshore wind (17 mph): it holds up and grooms the waves
- Falling tide (high tide at 1:59 pm)
- Light: First light 5:48 am · sunrise 6:11 am · sunset 5:29 pm · last light 5:52 pm
- Tide: high 1:05 am (18.1 ft), low 7:25 am (1.0 ft), high 1:59 pm (18.3 ft) and low 7:50 pm (5.5 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 77.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 22 kJ · Low power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has light offshore wind, though with a short-period swell. 1:00 pm to 5:00 pm can also work, though with a short-period swell, wind swell and onshore wind.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.
Diving in Jinhu today
Diving and snorkeling today
Likely visibility: fair- Tidal current running: mid-tide, the water is moving
- 2.0 ft swell at 5 s from the east-northeast: some surge on the bottom
- Light offshore wind (10 mph)
- 0.5 mph current toward the west-southwest, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 1:05 am (12:50–1:20 am), low tide 7:25 am (7:00–7:50 am), high tide 1:59 pm (1:40–2:20 pm) and low tide 7:50 pm (7:20–8:10 pm)
- Likely visibility: fair. Swell (up to 3.3 ft at 6 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 77.0 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 5:52 pm. Waning gibbous (88%), rising at 8:02 pm: a bright night.
Your diving day at a glance
The best window, 9:30 am to 11:30 am, combines light wind, weak current and the sun high, though with tidal current. Also worth a look from 1:30 pm to 2:30 pm, with slack water at high tide, little swell and the sun high, though with moderate wind and current. Also worth a look from 6:30 am to 8:10 am, with slack water at low tide, though with moderate wind and 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- 1:10–3:10 am Major · the moon passes overhead · high activity
- 1:43–3:43 pm Major · the moon passes underfoot · high activity
- 8:52–9:52 am Minor · moonset · medium activity
- 7:32–8:32 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.3 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow near shore: you only reach 33 ft at 0.9 mi. For dives deeper than 33 ft, 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).
