Tides in Old Harbor
Today's high and low tides
- ▲ High tide 3:46 am 7.8 ft · coef. 95
- ▼ Low tide 9:10 am 2.4 ft
- ▲ High tide 3:15 pm 10.0 ft · coef. 92
- ▼ Next low tide 10:07 pm -1.4 ft
↓ Falling The tide is falling. 3 h 43 min to low tide at 10:07 pm.
Tide coefficient 95 for the 3:46 am high tide and 92 for the 3:15 pm high tide. Spring tides. The water rises and falls 11.4 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 (10.5 ft) and the lowest, on June 15 (-2.6 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 98, 11.7 ft range). The smallest, on October 18 (coefficient 29, 4.6 ft).

The waves you may find
- Most commonMost common1.2 ft
- Significant2.3 ft

Wind on the coast and offshore
Cross-shore wind. The coast faces southwest and the wind blows along the shore: drift and current run parallel to the beach.

Moon phase and position
Today the moon is 226,428 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 3:02–5:02 am Major · the moon passes overhead · high activity
- 3:34–5:34 pm Major · the moon passes underfoot · high activity
- 1:26–2:26 pm Minor · moonset · medium activity
- 6:38–7:38 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.
