Tides in Costa Mesa
Today's high and low tides
- ▲ High tide 12:55 am 2.0 ft · coef. 77
- ▼ Next low tide 6:31 am 0.5 ft
- ▲ High tide 11:41 am 3.5 ft · coef. 71
- ▼ Low tide 8:48 pm -0.1 ft
↓ Falling The tide is falling. 3 h 26 min to low tide at 6:31 am.
Tide coefficient 77 for the 12:55 am high tide and 71 for the 11:41 am high tide. Average coefficient. The water rises and falls 3.6 ft between the highest high and the lowest low: an average 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 (3.9 ft) and the lowest, on January 3 (-0.4 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, 3.2 ft range). The smallest, on October 17 (coefficient 22, 0.0 ft).

Where this tide comes from
Costa Mesa has no station of its own, so we use the tide at Santa Ana River Entrance (Inside, NOAA), 2.4 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. 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 Costa Mesa
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.2 ft
- Significant2.4 ft
- Highest expectedHighest4.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.6 ft. Before heading out, expect waves of up to 4.6 ft.
Wind on the coast and offshore
Offshore wind. The coast faces southwest and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Sunday 1: 5.8 ft with a period of 9 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 Costa Mesa today
Surf today
Good- 2.2–3.3 ft surf at the shore, a fun size for most surfers
- 2.1 ft swell at 13 s from the south-southwest, clean
- Almost no wind (4 mph): glassy water
- Falling tide (low tide at 8:48 pm)
Rip current risk today: low · tomorrow: low (NWS)
Rip currents can still form near jetties, piers and reefs: swim near a lifeguard.
Surf height from the NWS, today: 1.0–3.0 ft
- Light: First light 6:43 am · sunrise 7:08 am · sunset 6:02 pm · last light 6:28 pm
- Tide: high 12:55 am (2.0 ft), low 6:31 am (0.5 ft), high 11:41 am (3.5 ft) and low 8:48 pm (-0.1 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 72.7 °F: a rash guard or a neoprene top.
- Energy: 134 kJ · Medium power
Today’s surf at a glance
The best window, 1:00 pm to 2:00 pm, has a good size, a clean swell and glassy water. 8:00 am to 12:00 pm also works, with a good size, a clean swell and glassy water.
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 Costa Mesa today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (11:41 am): little current from 11:20 am to 1:00 pm
- 2.0 ft swell at 13 s from the south-southwest: some surge on the bottom
- Light onshore wind (4 mph)
- 0.2 mph current toward the northeast, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 12:55 am (12:10–2:00 am), low tide 6:31 am (5:20–7:00 am), high tide 11:41 am (11:20 am–1:00 pm) and low tide 8:48 pm (7:30–9:30 pm)
- Likely visibility: good. Swell (up to 2.0 ft at 13 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 72.7 °F: a 3 mm wetsuit.
- Snorkeling: doable, with some waves or wind.
- Night dive: dark from 6:28 pm. Waning gibbous (83%), rising at 9:02 pm: a bright night.
Your diving day at a glance
The best window, 10:40 am to 1:00 pm, combines slack water at high tide, light wind, weak current and the sun high. Also good from 6:40 am to 8:00 am, with slack water at low tide, light wind and weak current. Also worth a look from 2:00 pm to 2:50 pm, with light wind, weak current and the sun high, though with some swell.
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 226,837 mi away and looks 32′ 43″ across.
Solunar periods
Today's activity: medium- 2:38–4:38 am Major · the moon passes overhead · high activity
- 3:11–5:11 pm Major · the moon passes underfoot · high activity
- 10:49–11:49 am Minor · moonset · medium activity
- 8:32–9:32 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 800 ft): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. 33 ft deep 0.5 mi from shore; 66 ft is far out (1.4 mi): for deeper dives, go by boat.
