Sea stateSea state: slight
The waves you may find
- Most commonMost common1.9 ft
- Significant3.7 ft
- Highest expectedHighest7.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 7.6 ft. Before heading out, expect waves of up to 7.6 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
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 ease over the next few days. The biggest waves arrive on Thursday 29: 4.8 ft with a period of 7 s, from the northwest (moderate).

- 3.0 ft swell at 6 s from the north-northwest, short: weak, messy waves

- Rising tide (high tide at 11:46 am)
- Light: First light 6:03 am · sunrise 6:25 am · sunset 6:20 pm · last light 6:42 pm
- Tide: low 5:47 am (0.9 ft), high 11:46 am (5.4 ft), low 5:41 pm (1.4 ft) and high 12:00 am (6.2 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 86.0 °F: boardshorts or a swimsuit and a rash guard.
- Energy: 60 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. 6:03 am to 7:00 am can also work, with a good size, though with a short-period 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 Sabang today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (11:46 am): little current from 11:30 am to 12:01 pm
- 2.9 ft swell at 6 s from the west-northwest: some surge on the bottom
- Light cross-shore wind (7 mph)
- 1.8 mph current toward the west, strong (model)
- Sun high: more light underwater
- Slack water today: low tide 5:47 am (5:20–6:10 am), high tide 11:46 am (11:30 am–12:01 pm), low tide 5:41 pm (5:10–6:10 pm) and high tide 12:00 am (11:40 pm–12:20 am)
- Likely visibility: fair. Swell (up to 3.8 ft at 6 s) and rain (0.45 in) over the last few days have stirred up the water. Based on the last 24 hours of data.
- Water at 86.0 °F: a shorty or a rash guard.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:42 pm. Waning gibbous (87%), rising at 9:23 pm: a bright night.
Your diving day at a glance
The best window, 11:00 am to 12:40 pm, combines slack water at high tide, light wind and the sun high, though with current. Also worth a look from 4:50 pm to 6:20 pm, with slack water at low tide and light wind, 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.
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 226,507 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:47–3:47 am Major · the moon passes overhead · high activity

- 8:45–9:45 am Minor · moonset · medium activity
- 8:53–9:53 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 0.55 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. Shore diving works here: 33 ft at 0.6 mi and 66 ft at 0.65 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
