Moon phase and position
Today the moon is 226,507 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 1:18–3:18 am Major · the moon passes overhead · high activity
- 1:50–3:50 pm Major · the moon passes underfoot · high activity
- 8:30–9:30 am Minor · moonset · medium activity
- 8:10–9:10 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.

- 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 0.6 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 near shore: you only reach 33 ft at 2.3 mi. For dives deeper than 33 ft, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
