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

Where this tide comes from
Tudumari Beach has no station of its own, so we use the tide at Iriomotejima (JMA), 5.3 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 Tudumari Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.7 ft
- Significant3.5 ft
- Highest expectedHighest7.1 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.1 ft. Before heading out, expect waves of up to 7.1 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 northwest 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 Thursday 29: 5.1 ft with a period of 7 s, from the north-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 Tudumari Beach today
Surf today
Poor- 2.4–3.7 ft surf at the shore, a fun size for most surfers
- 3.6 ft swell at 6 s from the north, short: weak, messy waves
- Light cross-shore wind (11 mph): a bit of chop
- Rising tide (high tide at 10:31 am)
- Light: First light 6:26 am · sunrise 6:50 am · sunset 6:07 pm · last light 6:31 pm
- Tide: low 3:35 am (0.3 ft), high 10:31 am (5.0 ft), low 3:32 pm (3.0 ft) and high 9:19 pm (5.4 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 81.3 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 77 kJ · Low power
Today’s surf at a glance
The best window, 8:00 am to 12:00 pm, has a good size, though with a short-period swell. 2:00 pm to 6:00 pm can also work, with a good size, 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.
Diving in Tudumari Beach today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (10:31 am): little current from 10:00 am to 11:00 am
- 3.4 ft swell at 6 s from the north: some surge on the bottom
- Light cross-shore wind (9 mph)

- Likely visibility: poor. Swell (up to 5.4 ft at 8 s) and wind over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 81.3 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:31 pm. Waning gibbous (88%), rising at 8:40 pm: a bright night.
Your diving day at a glance
The best window, 9:30 am to 12:00 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 1:50 pm to 4:40 pm, with slack water at low tide, light wind and the sun high, though with 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- 1:48–3:48 am Major · the moon passes overhead · high activity
- 2:20–4:20 pm Major · the moon passes underfoot · high activity
- 9:30–10:30 am Minor · moonset · medium activity
- 8:10–9:10 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 0.65 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 0.7 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). The profile is turned slightly from the coast so it does not run into an island or a headland.
