Tides in Alameda
Today's high and low tides
- ▲ High tide 2:31 am 5.5 ft · coef. 87
- ▼ Low tide 7:14 am 2.7 ft
- ▲ High tide 1:24 pm 7.3 ft · coef. 84
- ▼ Next low tide 8:30 pm -1.4 ft
↓ Falling The tide is falling. 7 min to low tide at 8:30 pm.
Tide coefficient 87 for the 2:31 am high tide and 84 for the 1:24 pm high tide. Average coefficient. The water rises and falls 8.7 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 (7.9 ft) and the lowest, on June 15 (-2.3 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 11 (coefficient 91, 7.2 ft range). The smallest, from October 17 to 18 (coefficient 37, 4.2 ft).

The sea at Alameda
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.3 ft
- Highest expectedHighest2.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.7 ft. Before heading out, expect waves of up to 2.7 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces southwest 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 stay much the same all week. The biggest waves arrive on Sunday 1: 1.6 ft with a period of 7 s, from the west (smooth).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water cools over the next few days: about 64.2 °F by Tuesday 3.

Your diving day at a glance
The best window, 12:20 pm to 2:20 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 7:30 am to 8:10 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.
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- 1:52–3:52 am Major · the moon passes overhead · high activity
- 2:24–4:24 pm Major · the moon passes underfoot · high activity
- 10:13–11:13 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.

For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 2.6 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: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
