2026 extremes: the highest tide of the year is on August 14 (5.5 ft) and the lowest, on December 24 (-0.7 ft).
Mixed: two high and two low tides a day, but of quite different heights.
Heights above NLLW. Astronomical prediction: wind and air pressure can raise or lower the water by a few inches, and more in a storm. Not for navigation. NLLW

Where this tide comes from
Onagawa has no station of its own, so we use the tide at Ishinomaki (TICON-4), 10 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 Onagawa
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.1 ft
- Highest expectedHighest2.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.2 ft. Before heading out, expect waves of up to 2.2 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 Saturday 31: 4.8 ft with a period of 9 s, from the south-southeast (moderate).
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 64.3 °F by Wednesday 4.
Water warmer than normal for late October (+2.3 °F).

Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:34–2:34 am Major · the moon passes overhead · high activity
- 1:06–3:06 pm Major · the moon passes underfoot · high activity
- 9:00–10:00 am Minor · moonset · medium activity
- 6:11–7:11 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.
