↓ Falling The tide is falling. 3 h 18 min to low tide at 7:25 am.
Tide coefficient 83 for the 1:27 am high tide and 82 for the 1:40 pm high tide. Average coefficient. The water rises and falls 12.8 ft between the highest high and the lowest low: an average 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 (12.5 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, 13.2 ft range). The smallest, from October 18 to 19 (coefficient 48, 6.6 ft).

Where this tide comes from
Islesboro has no station of its own, so we use the tide at Castine (NOAA), 7.5 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. It is a NOAA subordinate station: its times and heights come from the Bar Harbor reference station with the official corrections.

The sea at Islesboro
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.2 ft
- Highest expectedHighest2.7 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.7 ft. Before heading out, expect waves of up to 2.7 ft.
Wind on the coast and offshore
Offshore wind. The coast faces northeast 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 Wednesday 4: 5.0 ft with a period of 5 s, from the south-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.

Your diving day at a glance
The best window, 7:10 am to 8:40 am, combines slack water at low tide, little swell, light wind and weak current. Also good from 12:10 pm to 1:30 pm, with slack water at high tide, light wind, weak current and the sun high.
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 226,746 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 2:13–4:13 am Major · the moon passes overhead · high activity
- 2:46–4:46 pm Major · the moon passes underfoot · high activity
- 11:08 am–12:08 pm Minor · moonset · medium activity
- 7:24–8:24 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. Shallow, gradual bottom (16 ft at 0.3 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. 33 ft deep 0.35 mi from shore; 66 ft is far out (2 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.
