The sea at East Devonport
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.2 ft. Before heading out, expect waves of up to 6.2 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces north 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 build over the next few days. The biggest waves arrive on Saturday 31: 4.3 ft with a period of 5 s, from the north-northwest (moderate).
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.

- 1.9 ft swell at 4 s from the northwest, short: weak, messy waves
- 2.0 ft wind swell at 3 s: messy waves

- Tide: high 2:29 am (11.0 ft), low 8:45 am (3.0 ft), high 2:26 pm (11.0 ft) and low 9:06 pm (0.7 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.

Today’s surf at a glance
The best window, 5:00 pm to 8:00 pm, has light offshore wind, though with a short-period swell and wind swell. 10:00 am to 1:00 pm can also work, with light offshore wind, though with a short-period swell. 6:00 am to 8:00 am can also work, though with a short-period swell.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.

Your diving day at a glance
The best window, 1:20 pm to 3:10 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 8:10 am to 9:20 am, with slack water at low tide, 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 226,459 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:14–4:14 am Major · the moon passes overhead · high activity
- 2:46–4:46 pm Major · the moon passes underfoot · high activity
- 7:08–8:08 am Minor · moonset · medium activity
- 11:28 pm–12:28 am 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 deep1.9 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 0.5 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 1.1 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).
