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

Where this tide comes from
Katakai has no station of its own, so we use the tide at Chiba Port (JMA), 20 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 Katakai
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.6 ft
- Significant3.2 ft
- Highest expectedHighest6.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.6 ft. Before heading out, expect waves of up to 6.6 ft.
Wind on the coast and offshore
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 build over the next few days. The biggest waves arrive on Wednesday 4: 6.3 ft with a period of 8 s, from the east-southeast (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 Katakai today
Surf today
Poor- 1.6–2.4 ft surf at the shore, a fun size for most surfers
- 2.0 ft swell at 7 s from the east-northeast, short: weak, messy waves
- Almost no wind (4 mph): glassy water
- Rising tide (low tide at 12:31 pm)
- Light: First light 5:31 am · sunrise 5:57 am · sunset 4:47 pm · last light 5:13 pm
- Tide: low 12:21 am (-0.1 ft), high 7:09 am (6.3 ft), low 12:31 pm (3.7 ft) and high 5:47 pm (6.5 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 72.1 °F: a rash guard or a neoprene top.
- Energy: 36 kJ · Low power
Today’s surf at a glance
The best window, 6:00 am to 9:00 am, has glassy water, though with a short-period swell. 2:00 pm to 5:00 pm can also work, though with a short-period swell. 10:00 am to 12:00 pm can also work, though with a short-period swell.
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.

Your diving day at a glance
The best window, 11:20 am to 1:40 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 6:30 am to 8:00 am, with slack water at high tide, 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 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:38–2:38 am Major · the moon passes overhead · high activity
- 1:11–3:11 pm Major · the moon passes underfoot · high activity
- 8:54–9:54 am Minor · moonset · medium activity
- 6:26–7:26 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.

Water depth
Shallow, gradualShallow, gradual bottom: you need to go 1.1 mi out for 33 ft of water. Right off the beach it already drops to about 14 ft.
From the shoreline (0.35 mi from Katakai) out to sea, heading southeast.
How far from shore
- 16 ft deep0.35 mi
- 33 ft deep1.1 mi
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 14 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. Shallow near shore: you only reach 33 ft at 1.1 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).
