What is the tide coefficient?
2026 extremes: the highest tide of the year is on December 25 (8.2 ft) and the lowest, on April 18 (0.1 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above lower low water, large tide (LLWLT), the zero of Canadian charts. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. LLWLT

Where this tide comes from
Long Harbour-Mount Arlington Heights has no station of its own, so we use the tide at Argentia (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 waves you may find
- Most commonMost common1.1 ft
- Significant2.3 ft

One wave in seven is higher than the significant height, and about 3 times a day one reaches 4.8 ft. Before heading out, expect waves of up to 4.8 ft.
Wind on the coast and offshore
Onshore wind. The coast faces southwest and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Monday 2: 4.1 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 is steady these days, with no sudden changes.

Moon phase and position
Today the moon is 226,704 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 2:40–4:40 am Major · the moon passes overhead · high activity
- 3:13–5:13 pm Major · the moon passes underfoot · high activity
- 11:51 am–12:51 pm Minor · moonset · medium activity
- 7:34–8:34 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. Very shallow: the water doesn't reach 16 ft within 0.3 mi. Cast far from the beach, ideally around high tide.
- 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: the water doesn't reach 33 ft within 0.3 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide. There is land ahead (an island, a headland or the far shore) 0.3 mi out.
