The sea at Alcatraz
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.6 ft
- Significant3.2 ft
- Highest expectedHighest6.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.5 ft. Before heading out, expect waves of up to 6.5 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Thursday 29: 3.5 ft with a period of 8 s, from the north (slight).
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 (+2.7 °F).

The moon in Alcatraz
Moon phase and position
Today the moon is 226,666 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 2:02–4:02 am Major · the moon passes overhead · high activity
- 2:34–4:34 pm Major · the moon passes underfoot · high activity
- 9:22–10:22 am Minor · moonset · medium activity
- 8:47–9:47 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.

Water depth

- 33 ft deep1,250 ft
- 66 ft deep0.3 mi
- 164 ft deep0.4 mi
For fishing, swimming and diving
- Shore fishing. 33 ft of water just 1,250 ft from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shore diving works here: 33 ft at 1,250 ft and 66 ft at 0.3 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
