Tides in Belfast
Today's high and low tides
- ▲ High tide 12:32 am 11.1 ft · coef. 85
- ▼ Low tide 6:28 am 0.1 ft
- ▲ High tide 12:43 pm 12.4 ft · coef. 84
- ▼ Next low tide 7:06 pm -1.1 ft
↓ Falling The tide is falling. 1 h 13 min to low tide at 7:06 pm.
Tide coefficient 85 for the 12:32 am high tide and 84 for the 12:43 pm high tide. Average coefficient. The water rises and falls 13.5 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 June 15 (12.8 ft) and the lowest, on December 25 (-1.7 ft).
Semidiurnal: two high and two low tides a day, of similar height.
Heights above mean lower low water (MLLW), the zero of US 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. MLLW
Tide coefficient and range in October
The biggest tides of the month came from October 26 to 29 (coefficient 85, 13.4 ft range). The smallest, from October 18 to 19 (coefficient 48, 6.7 ft).

Where this tide comes from
Tides from the Belfast station (NOAA), 0.1 mi from Belfast. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Bar Harbor reference station with the official corrections.

The sea at Belfast
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.2 ft
- Highest expectedHighest2.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.5 ft. Before heading out, expect waves of up to 2.5 ft.
Wind on the coast and offshore
Cross-offshore wind. The coast faces east 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 build over the next few days. The biggest waves arrive on Thursday 29: 2.6 ft with a period of 4 s, from the south-southwest (slight).

Your diving day at a glance
The best window, 11:40 am to 1:50 pm, combines slack water at high tide, small waves, light wind, weak current and the sun high. Also good from 7:10 am to 8:00 am, with small waves, 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 Belfast
Moon phase and position
Today the moon is 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:10–3:10 am Major · the moon passes overhead · high activity
- 1:41–3:41 pm Major · the moon passes underfoot · high activity
- 9:57–10:57 am Minor · moonset · medium activity
- 6:22–7:22 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 2.5 mi out for 33 ft of water.
From the shoreline (1,250 ft from Belfast) out to sea, heading east.
How far from shore
- 16 ft deep1.2 mi
- 33 ft deep2.5 mi
- 66 ft deepnot within 3.1 mi
- 164 ft deepnot within 3.1 mi
For fishing, swimming and diving
- Shore fishing. Shallow, gradual bottom (16 ft at 1.2 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. Shallow near shore: you only reach 33 ft at 2.5 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. The profile is turned slightly from the coast so it does not run into an island or a headland.
