Mixed, mainly diurnal: on many days there is only one high and one low tide.

Where this tide comes from
Port Hughes has no station of its own, so we use the tide at Wallaroo (TICON-4), 11 mi away. On the open coast the difference is usually a few minutes and inches; inside estuaries, rivers and enclosed bays it can be much larger.

The sea at Port Hughes
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.0 ft
- Significant1.9 ft
- Highest expectedHighest3.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.7 ft. Before heading out, expect waves of up to 3.7 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces west 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 build over the next few days. The biggest waves arrive on Wednesday 4: 5.6 ft with a period of 6 s, from the southwest (moderate).
Water temperature
Water temperature →Water temperature changes how fish behave: in very cold or very warm water they feed less. The water warms over the next few days: about 68.0 °F by Wednesday 4.
Water warmer than normal for late October (+4.6 °F).

Your diving day at a glance
The best window, 2:10 pm to 3:10 pm, combines slack water at low tide, light wind and the sun high, though with current. Also worth a look from 6:20 am to 7:10 am, with slack water at high tide and light wind, though with current. Also worth a look from 6:20 pm to 7:50 pm, with slack water at high tide and light wind, though with 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 226,463 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:20–4:20 am Major · the moon passes overhead · high activity
- 2:53–4:53 pm Major · the moon passes underfoot · high activity
- 7:41–8:41 am Minor · moonset · medium activity
- 11:07 pm–12:07 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.

For fishing, swimming and diving
- Shore fishing. Deep water close in: about 14 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. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
