Tides in Princeton
Today's high and low tides
- ▲ Next high tide 2:12 am 4.1 ft · coef. 79
- ▼ Low tide 6:30 am 2.8 ft
- ▲ High tide 12:42 pm 6.4 ft · coef. 75
- ▼ Low tide 8:18 pm -0.9 ft
↑ Rising The tide is rising. 8 min to high tide at 2:12 am.
Tide coefficient 79 for the 2:12 am high tide and 75 for the 12:42 pm high tide. Average coefficient. The water rises and falls 7.3 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 December 24 (7.3 ft) and the lowest, on June 15 (-2.1 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 10 (coefficient 94, 6.0 ft range). The smallest, from October 17 to 18 (coefficient 35, 4.0 ft).

Where this tide comes from
Tides from the Pillar Point Harbor station (NOAA), 0.3 mi from Princeton. Times and heights are its predictions.

The sea at Princeton
Sea stateSea state: moderate
The waves you may find
- Most commonMost common2.8 ft
- Significant5.6 ft
- Highest expectedHighest11 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 11 ft. Before heading out, expect waves of up to 11 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces west and the wind comes off the land at an angle: calmer water near the shore, and bait and boats 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: 7.0 ft with a period of 8 s, from the west-northwest (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 Princeton today
Surf today
Fair- 2.5–3.8 ft surf at the shore, a fun size for most surfers
- 4.1 ft swell at 6 s from the northwest, short: weak, messy waves
- Light offshore wind (4 mph): it holds up and grooms the waves
- First or last light of the day
- Rising tide (high tide at 12:42 pm)
- Light: First light 7:05 am · sunrise 7:32 am · sunset 6:15 pm · last light 6:42 pm
- Tide: high 2:12 am (4.1 ft), low 6:30 am (2.8 ft), high 12:42 pm (6.4 ft) and low 8:18 pm (-0.9 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 63.7 °F: a 3/2 fullsuit.
- Energy: 95 kJ · Low power
Today’s surf at a glance
The best window, 7:05 am to 11:00 am, has a good size and light offshore wind, though with a short-period swell. 2:00 pm to 6:00 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 Princeton today
Diving and snorkeling today
Likely visibility: fair- Slack water around high tide (12:42 pm): little current from 12:10 pm to 1:10 pm
- 4.1 ft swell at 6 s from the northwest: some surge on the bottom
- Light onshore wind (6 mph)
- 0.2 mph current toward the north, weak (model)
- Sun high: more light underwater
- Slack water today: high tide 2:12 am (1:40–2:50 am), low tide 6:30 am (5:40–7:10 am), high tide 12:42 pm (12:10–1:10 pm) and low tide 8:18 pm (7:50–8:40 pm)
- Likely visibility: fair. Swell (up to 5.9 ft at 6 s) over the last few days has stirred up the water. Based on the last 24 hours of data.
- Water at 63.7 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 6:42 pm. Waning gibbous (83%), rising at 9:08 pm: a bright night.
Your diving day at a glance
The best window, 11:30 am to 1:40 pm, combines slack water at high tide, light wind, weak current and the sun high, though with some swell. Also worth a look from 7:30 am to 8:30 am, with light wind and weak current, 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.

The moon in Princeton
Moon phase and position
Today the moon is 226,837 mi away and looks 32′ 43″ across.
Solunar periods
Today's activity: medium- 2:57–4:57 am Major · the moon passes overhead · high activity
- 3:30–5:30 pm Major · the moon passes underfoot · high activity
- 11:22 am–12:22 pm Minor · moonset · medium activity
- 8:38–9:38 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 0.4 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.
