Tides in Greenbrae
Today's high and low tides
- ▲ High tide 3:05 am 4.7 ft · coef. 86
- ▼ Low tide 7:51 am 2.6 ft
- ▲ High tide 1:43 pm 6.6 ft · coef. 85
- ▼ Next low tide 9:00 pm -0.8 ft
↓ Falling The tide is falling. 6 h 6 min to low tide at 9:00 pm.
Tide coefficient 86 for the 3:05 am high tide and 85 for the 1:43 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 July 12 (7.1 ft) and the lowest, on June 16 (-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 26 to 29 (coefficient 86, 7.3 ft range). The smallest, from October 18 to 19 (coefficient 42, 4.1 ft).

The sea at Greenbrae
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.3 ft
- Highest expectedHighest2.6 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.6 ft. Before heading out, expect waves of up to 2.6 ft.
Wind on the coast and offshore
Onshore wind. The coast faces southeast 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 stay much the same all week. The biggest waves arrive on Wednesday 28: 1.6 ft with a period of 8 s, from the west (smooth).

Your diving day at a glance
The best window, 12:50 pm to 2:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 7:30 am to 8:30 am, with slack water at low tide, little swell, 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.

Moon phase and position
Today the moon is 226,426 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 1:53–3:53 am Major · the moon passes overhead · high activity
- 2:25–4:25 pm Major · the moon passes underfoot · high activity
- 10:15–11:15 am Minor · moonset · medium activity
- 7:32–8:32 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.

- 33 ft deep2.8 mi
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.5 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. Shallow near shore: you only reach 33 ft at 2.8 mi. For dives deeper than 33 ft, go by boat.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
