Tides in Sem
Today's high and low tides
- ▲ High tide 6:19 am 2.3 ft · coef. 69
- ▼ Next low tide 11:56 am 1.5 ft
- ▲ High tide 6:51 pm 2.4 ft · coef. 68
↓ Falling The tide is falling. 3 h 52 min to low tide at 11:56 am.
Tide coefficient 69 for the 6:19 am high tide and 68 for the 6:51 pm high tide. Low coefficient. The water rises and falls 1.0 ft between the highest high and the lowest low: a large range for this place. 70 is an average tide here; 90 and above means spring tides; below 45, neap tides. What is the tide coefficient?
2026 extremes: the highest tide of the year is on August 22 (2.7 ft) and the lowest, on March 29 (0.8 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above chart datum (CD), the zero of that port's nautical 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. chart datum (CD)
Tide coefficient and range in October
The biggest tides of the month came from October 6 to 7 (coefficient 89, 1.2 ft range). The smallest, from October 14 to 15 (coefficient 47, 0.7 ft).

Where this tide comes from
Tides from the Sem station (Kartverket), 0.0 mi from Sem. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Viker reference station with the official corrections.

The sea at Sem
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.7 ft
- Significant1.4 ft
- Highest expectedHighest3.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 3.0 ft. Before heading out, expect waves of up to 3.0 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces southeast 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 stay much the same all week. The biggest waves arrive on Thursday 29: 2.2 ft with a period of 5 s, from the south-southwest (slight).
Water temperature
Water temperature →The satellite measured 3.2 °F more 2 days ago than the model gives now: the water is probably warmer than the forecast says.
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 48.8 °F by Wednesday 4.
Water warmer than normal for late October (+1.4 °F).

Your diving day at a glance
The best window, 11:00 am to 12:30 pm, combines slack water at low tide, little swell, light wind, weak current and the sun high. Also good from 3:30 pm to 4:30 pm, with little swell, 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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

The moon in Sem
Moon phase and position
Today the moon is 226,618 mi away and looks 32′ 45″ across.
Solunar periods
Today's activity: high- 1:42–3:42 am Major · the moon passes overhead · high activity
- 2:14–4:14 pm Major · the moon passes underfoot · high activity
- 12:46–1:46 pm Minor · moonset · medium activity
- 4:42–5:42 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.

Water depth
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 600 ft from shore.
From the shoreline (2 mi from Sem) out to sea, heading east.
How far from shore
- 16 ft deep250 ft
- 33 ft deep600 ft
- 66 ft deepnot within 0.85 mi
- 164 ft deepnot within 0.85 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 25 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. 33 ft deep 600 ft from shore; 66 ft is far out (beyond 0.85 mi): for deeper dives, go by boat.
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) 0.85 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland. Right by the shore the bottom may drop even faster than shown. Where the bottom comes up to the surface there are shoals, rocks or an islet next to the profile.
