Mixed: two high and two low tides a day, but of quite different heights.

Where this tide comes from

The sea at Ōarai
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.3 ft
- Significant2.6 ft
- Highest expectedHighest5.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 5.2 ft. Before heading out, expect waves of up to 5.2 ft.
Wind on the coast and offshore
Cross-onshore wind. The coast faces east and the wind comes in from the sea at an angle: a bit more surf at the shore and drift along the coast, toward land.
Wave height, next 7 daysWaves, next 7 days
Waves build over the next few days. The biggest waves arrive on Friday 30: 5.9 ft with a period of 8 s, from the 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 67.8 °F by Wednesday 4.
Water about normal for late October.

Today’s surf at a glance
The best window is 6:00 am to 8:00 am. 10:00 am to 2:00 pm can also work, though with a short-period swell.
An estimate for this stretch of coast, not for a specific break: every beach or reef works its own way (its tide, bottom and angle). Check it when you get there.
Follow the flags and the lifeguards, and don’t paddle out if the surf is above your level: this score is a guide, not a substitute for what you see when you get there.

The best window, 9:40 am to 12:40 pm, combines slack water at low tide, light wind, weak current and the sun high. Also good from 6:00 am to 7:20 am, with slack water at high tide, light wind and weak current. Also good from 3:50 pm to 4:50 pm, with slack water at high tide, 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.

Moon phase and position
Today the moon is 226,480 mi away and looks 32′ 46″ across.
Solunar periods
Today's activity: medium- 12:38–2:38 am Major · the moon passes overhead · high activity
- 1:10–3:10 pm Major · the moon passes underfoot · high activity
- 8:56–9:56 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.

For fishing, swimming and diving
- Shore fishing. 33 ft of water just 0.3 mi from shore: a good cast reaches deep water. Current and surf hit harder here.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. 33 ft deep 0.3 mi from shore; 66 ft is far out (1.5 mi): for deeper dives, go by boat.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
