Tides in Long Beach
Today's high and low tides
- ▼ Low tide 4:11 am 2.0 ft
- ▲ High tide 10:36 am 6.5 ft · coef. 83
- ▼ Next low tide 6:03 pm -0.7 ft
↓ Falling The tide is falling. 4 h 10 min to low tide at 6:03 pm.
Tide coefficient 83 for the 10:36 am high tide. Average coefficient. The water rises and falls 7.1 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 December 24 (7.0 ft) and the lowest, on January 3 (-1.8 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above mean lower low water (MLLW), the zero of US 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. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 8 to 9 (coefficient 103, 5.5 ft range). The smallest, on October 17 (coefficient 22, 3.4 ft).

Where this tide comes from
Tides from the Long Beach station (NOAA), 1.2 mi from Long Beach. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Los Angeles (Outer Harbor) reference station with the official corrections.

The sea at Long Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.2 ft
- Significant2.5 ft
- Highest expectedHighest5.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.0 ft. Before heading out, expect waves of up to 5.0 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces south 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 Sunday 1: 5.2 ft with a period of 8 s, from the west-southwest (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 Long Beach today
Surf today
Fair- 1.5–2.3 ft surf at the shore, a fun size for most surfers
- 2.0 ft swell at 9 s from the southwest, a bit short
- Almost no wind (3 mph): glassy water
- Rising tide (high tide at 10:36 am)
Rip current risk today: moderate · tomorrow: moderate (NWS)
Dangerous rip currents are possible: swim only near a lifeguard and follow the flags. If one pulls you out, swim parallel to the shore.
Surf height from the NWS, today: 2.0–4.0 ft
- Light: First light 6:43 am · sunrise 7:09 am · sunset 6:04 pm · last light 6:30 pm
- Tide: low 4:11 am (2.0 ft), high 10:36 am (6.4 ft) and low 6:03 pm (-0.7 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 72.3 °F: a rash guard or a neoprene top.

Today’s surf at a glance
The best window, 8:00 am to 12:00 pm, has glassy water. 5:00 pm to 6:00 pm also works.
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.
Diving in Long Beach today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (10:36 am): little current from 10:10 am to 11:00 am
- 2.0 ft swell at 9 s from the southwest: some surge on the bottom
- Almost no wind
- 0.4 mph current toward the north, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 11:31 pm (11:00 pm–12:10 am), low tide 4:11 am (3:30–4:40 am), high tide 10:36 am (10:10–11:00 am) and low tide 6:03 pm (5:40–6:30 pm)
- Likely visibility: good. Swell (up to 2.0 ft at 10 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 72.3 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:30 pm. Waning gibbous (91%), rising at 7:59 pm: a bright night.
Your diving day at a glance
The best window, 9:40 am to 11:00 am, combines slack water at high tide, light wind, weak current and the sun high. Also good from 5:20 pm to 6:00 pm, with slack water at low 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Long Beach
Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:35–3:35 am Major · the moon passes overhead · high activity
- 2:07–4:07 pm Major · the moon passes underfoot · high activity
- 9:42–10:42 am Minor · moonset · medium activity
- 7:29–8:29 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
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 150 ft from shore.

- 33 ft deep150 ft
- 66 ft deep800 ft
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 36 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. Shore diving works here: 33 ft at 150 ft and 66 ft at 800 ft from shore.
Right by the shore the bottom may drop even faster than shown.
