The sea at Mombetsu
Sea stateSea state: moderate
The waves you may find
- Most commonMost common3.0 ft
- Significant6.0 ft
- Highest expectedHighest12 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 12 ft. Before heading out, expect waves of up to 12 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces northeast 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 ease over the next few days. The biggest waves arrive on Thursday 29: 7.2 ft with a period of 9 s, from the north-northeast (moderate).
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 46.9 °F by Wednesday 4.
Water warmer than normal for late October (+1.2 °F).

- First or last light of the day
- Rising tide (high tide at 3:12 pm)
- Light: First light 5:29 am · sunrise 5:59 am · sunset 4:21 pm · last light 4:51 pm

- Energy: 450 kJ · Medium power
Today’s surf at a glance
The best window, 5:29 am to 9:00 am, has a good size and light offshore wind.
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.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

Your diving day at a glance
The best window, 2:30 pm to 3:40 pm, combines slack water at high tide, light wind and weak current, though with some swell. Also worth a look from 8:10 am to 9:10 am, with light wind and the sun high, though with a big swell and 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 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:26–2:26 am Major · the moon passes overhead · high activity
- 12:58–2:58 pm Major · the moon passes underfoot · high activity
- 9:18–10:18 am Minor · moonset · medium activity
- 5:37–6:37 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 0.3 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. Shore diving works here: 33 ft at 0.45 mi and 66 ft at 0.9 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).
