Tides in Koper
Today's high and low tides
- ▼ Low tide 3:52 am 0.9 ft
- ▲ High tide 9:58 am 3.3 ft · coef. 92
- ▼ Low tide 4:55 pm -0.3 ft
- ▲ Next high tide 11:22 pm 2.4 ft · coef. 85
↑ Rising The tide is rising. 1 h 31 min to high tide at 11:22 pm.
Tide coefficient 92 for the 9:58 am high tide and 85 for the 11:22 pm high tide. Spring tides. The water rises and falls 3.6 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 October 26 (3.4 ft) and the lowest, on July 15 (-1.0 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above MLWS. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. MLWS
Tide coefficient and range in October
The biggest tides of the month came from October 9 to 10 (coefficient 108, 3.6 ft range). The smallest, on October 3 (coefficient 20, 1.5 ft).

Where this tide comes from
Koper has no station of its own, so we use the tide at Trieste (TICON-4), 7.0 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 Koper
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.2 ft
- Significant0.4 ft
- Highest expectedHighest0.9 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.9 ft. Before heading out, expect waves of up to 0.9 ft.
Wind on the coast and offshore
Offshore wind. The coast faces west and the wind blows from land out to sea: calm shore and clean waves, but watch the drift out to sea.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Tuesday 3: 2.6 ft with a period of 3 s, from the northeast (slight).
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 62.5 °F by Tuesday 3.

Your diving day at a glance
The best window, 9:00 am to 10:50 am, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 4:20 pm to 5:00 pm, with slack water at low tide, 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.

Moon phase and position
Today the moon is 226,461 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 12:25–2:25 am Major · the moon passes overhead · high activity
- 12:56–2:56 pm Major · the moon passes underfoot · high activity
- 9:13–10:13 am Minor · moonset · medium activity
- 5:34–6:34 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.

Water depth
Shallow, gradualShallow, gradual bottom: you need to go 2.1 mi out for 33 ft of water. Right off the beach it already drops to about 10 ft.
From the shoreline (0.3 mi from Koper) out to sea, heading west.
How far from shore
- 16 ft deep700 ft
- 33 ft deep2.1 mi
- 66 ft deep2.9 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. About 10 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- 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 near shore: you only reach 33 ft at 2.1 mi. For dives deeper than 33 ft, 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.
