↓ Falling The tide is falling. 4 h 44 min to low tide at 9:40 pm.
Tide coefficient 94 for the 3:13 am high tide and 92 for the 2:55 pm high tide. Spring tides. The water rises and falls 21.7 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 December 24 (20.0 ft) and the lowest, on June 16 (-4.1 ft).
Mixed: two high and two low tides a day, but of quite different heights.
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 27 (coefficient 97, 22.2 ft range). The smallest, on October 18 (coefficient 30, 8.8 ft).

Where this tide comes from
Tides from the Petersburg station (NOAA), 0.9 mi from Kupreanof. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Ketchikan reference station with the official corrections.

The sea at Kupreanof
Sea stateSea state: calm (rippled)
The waves you may find
- Most commonMost common0.1 ft
- Significant0.1 ft
- Highest expectedHighest0.3 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 0.3 ft. Before heading out, expect waves of up to 0.3 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 Sunday 1: 0.9 ft with a period of 2 s, from the southeast (smooth).

Moon phase and position
Today the moon is 226,428 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:37–3:37 am Major · the moon passes overhead · high activity
- 2:09–4:09 pm Major · the moon passes underfoot · high activity
- 11:55 am–12:55 pm Minor · moonset · medium activity
- 5:18–6:18 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.
