The water rises and falls 4.3 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on July 13 (6.4 ft) and the lowest, on January 4 (0.2 ft).
Mixed: two high and two low tides a day, but of quite different heights.

Where this tide comes from
Tides from the Ruibin–Shuinandong coast station (CWA), 1.6 mi from Jiufen. Times and heights are its predictions.

The sea at Jiufen
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.2 ft
- Significant4.3 ft
- Highest expectedHighest8.8 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 8.8 ft. Before heading out, expect waves of up to 8.8 ft.
Wind on the coast and offshore
Cross-shore wind. The coast faces north and the wind blows along the shore: drift and current run parallel to the beach.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 6.3 ft with a period of 7 s, from the 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 Jiufen today
Surf today
Good- 3.4–5.2 ft surf at the shore, a good size with some punch
- 5.2 ft swell at 6 s from the northeast, short: weak, messy waves
- Almost no wind (4 mph): glassy water
- Rising tide (high tide at 11:58 am)
- Light: First light 5:35 am · sunrise 5:58 am · sunset 5:14 pm · last light 5:38 pm
- Tide: low 3:32 am (1.5 ft), high 11:58 am (5.8 ft), low 5:12 pm (4.5 ft) and high 9:10 pm (4.9 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 79.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 194 kJ · Medium power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has a good size and glassy water, though with a short-period swell. 2:00 pm to 5:38 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 Jiufen today
Diving and snorkeling today
Likely visibility: poor- Slack water around high tide (11:58 am): little current from 11:40 am to 12:20 pm
- 4.5 ft swell at 6 s from the northeast: some surge on the bottom
- Light cross-shore wind (5 mph)
- 1.1 mph current toward the west-northwest (model)
- Sun high: more light underwater
- Slack water today: low tide 3:32 am (3:17–3:50 am), high tide 11:58 am (11:40 am–12:20 pm), low tide 5:12 pm (4:10–6:20 pm) and high tide 9:10 pm (8:00–10:00 pm)
- Likely visibility: poor. Swell (up to 9.4 ft at 8 s) and rain (0.24 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 79.0 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 5:38 pm. Waning gibbous (88%), rising at 7:46 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 1:10 pm, combines slack water at high tide, light wind and the sun high, though with some swell and current. Also worth a look from 4:10 pm to 5:10 pm, with slack water at low tide and light wind, though with some swell 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.

Moon phase and position
Today the moon is 226,493 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:56–2:56 am Major · the moon passes overhead · high activity
- 1:28–3:28 pm Major · the moon passes underfoot · high activity
- 8:40–9:40 am Minor · moonset · medium activity
- 7:16–8:16 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. 33 ft of water just 800 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 800 ft and 66 ft at 950 ft from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
