Moon phase and position
Today the moon is 226,597 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: medium- 1:44–3:44 am Major · the moon passes overhead · high activity
- 2:16–4:16 pm Major · the moon passes underfoot · high activity
- 10:10–11:10 am Minor · moonset · medium activity
- 7:21–8:21 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
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 600 ft from shore. It reaches 164 ft at 1.7 mi.
From the shoreline (0.6 mi from Great Sand Beach) out to sea, heading south.
How far from shore
- 16 ft deep410 ft
- 33 ft deep600 ft
- 66 ft deep0.55 mi
- 164 ft deep1.7 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 8.9 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 600 ft and 66 ft at 0.55 mi from shore.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. Right by the shore the bottom may drop even faster than shown.
