Tides in Imperial Beach
Today's high and low tides
- ▼ Low tide 4:02 am 2.0 ft
- ▲ High tide 10:30 am 6.5 ft · coef. 84
- ▼ Next low tide 5:52 pm -0.6 ft
↓ Falling The tide is falling. 3 h 58 min to low tide at 5:52 pm.
Tide coefficient 84 for the 10:30 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 (-1.9 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 104, 5.7 ft range). The smallest, on October 17 (coefficient 20, 3.2 ft).

Where this tide comes from
Tides from the Imperial Beach station (NOAA), 1.3 mi from Imperial Beach. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the San Diego (Broadway) reference station with the official corrections.

The sea at Imperial Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.6 ft
- Significant3.1 ft
- Highest expectedHighest6.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.3 ft. Before heading out, expect waves of up to 6.3 ft.
Wind on the coast and offshore
Onshore wind. The coast faces west and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Sunday 1: 6.2 ft with a period of 8 s, from the south-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.
Water warmer than normal for late October (+8.7 °F).

Surf in Imperial Beach today
Surf today
Fair- 1.9–2.9 ft surf at the shore, a fun size for most surfers
- 1.8 ft swell at 13 s from the south-southwest, long-period and powerful
- Light onshore wind (9 mph): a bit of chop
- Falling tide (low tide at 5:52 pm)
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 6:37 am · sunrise 7:03 am · sunset 6:01 pm · last light 6:27 pm
- Tide: low 4:02 am (2.0 ft), high 10:30 am (6.5 ft) and low 5:52 pm (-0.6 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 73.6 °F: a rash guard or a neoprene top.
- Energy: 106 kJ · Medium power
Today’s surf at a glance
The best window, 5:00 pm to 6:00 pm, has a good size and a clean swell. 2:00 pm to 4:00 pm also works, with a good size and a clean 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.
Diving in Imperial Beach today

- Night dive: dark from 6:27 pm. Waning gibbous (91%), rising at 7:59 pm: a bright night.
Your diving day at a glance
The best window, 9:30 am to 11:20 am, combines slack water at high tide, light wind, weak current and the sun high. Also good from 5:10 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.

Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:31–3:31 am Major · the moon passes overhead · high activity

- 9:34–10:34 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 1,050 ft): 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 0.95 mi. For dives deeper than 33 ft, go by boat.
