Tide coefficient 88 for the 10:07 am high tide and 88 for the 10:22 pm high tide. Average coefficient. The water rises and falls 8.0 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 July 16 (9.3 ft) and the lowest, on December 27 (0.6 ft).
Semidiurnal: two high and two low tides a day, of similar height.

Where this tide comes from
Tides from the Tryphena station (LINZ), 3.7 mi from Medlands Beach. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Marsden Point reference station with the official corrections.

Modified: secondary port of the LINZ Secondary Ports table 2026-27 (https://www.linz.govt.nz/products-services/tides-and-tidal-streams/tide-predictions), computed by TidePlanet with the LINZ method from the harmonic constants of Marsden Point in the Slackwater database (https://github.com/openwatersio/slackwater-database).
The sea at Medlands Beach
Sea stateSea state: slight
The waves you may find
- Most commonMost common1.5 ft
- Significant3.0 ft
- Highest expectedHighest6.4 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 6.4 ft. Before heading out, expect waves of up to 6.4 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Cross-offshore wind. The coast faces northeast 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 Friday 30: 4.9 ft with a period of 5 s, from the west-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.
Water warmer than normal for late October (+1.3 °F).

Surf in Medlands Beach today
Surf today
Poor- 0.9–1.4 ft surf at the shore, small: good for learning or a longboard
- 1.2 ft swell at 5 s from the north-northwest, short: weak, messy waves; it hits this coast at an angle
- 2.2 ft wind swell at 3 s: messy waves
- Moderate offshore wind (14 mph): it holds up and grooms the waves
- Rising tide (high tide at 10:07 am)
- Light: First light 5:50 am · sunrise 6:18 am · sunset 7:47 pm · last light 8:14 pm
- Tide: low 3:49 am (0.8 ft), high 10:07 am (8.8 ft), low 4:16 pm (1.4 ft) and high 10:22 pm (8.4 ft). Every break has its own tide: some work at low tide and others at high tide. The tide doesn’t change the score here.
- Water at 61.9 °F: a 4/3 fullsuit.
- Energy: 15 kJ · Low power
Today’s surf at a glance
The best window, 6:00 am to 10:00 am, has light offshore wind, though with small waves, a short-period swell and wind 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.
Diving in Medlands Beach today
Diving and snorkeling today
Likely visibility: good- Slack water around high tide (10:07 am): little current from 9:50 am to 10:30 am
- 3.0 ft surface waves
- Fresh offshore wind (21 mph): it pushes surface swimmers away from shore
- 0.8 mph current toward the east (model)
- Sun high: more light underwater

- Likely visibility: good. The sea has been calm and there's been little rain. Based on the last 24 hours of data.
- Water at 61.9 °F: a 7 mm wetsuit, with hood and booties.
- Snorkeling: better not, with these waves, wind or current.
- Night dive: dark from 8:14 pm. Waning gibbous (89%), rising at 11:36 pm: a bright night.
Your diving day at a glance
The best window, 9:30 am to 11:00 am, combines slack water at high tide and the sun high, though with fresh wind and current. Also worth a look from 3:20 pm to 4:50 pm, with slack water at low tide, though with fresh wind and current. Also worth a look from 6:20 am to 8:30 am, with weak current, though with tidal current and moderate wind.
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.
Never dive alone and check with the local dive shop: this rating is a guide, not a substitute for a professional.

Moon phase and position
Today the moon is 226,442 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: medium- 2:12–4:12 am Major · the moon passes overhead · high activity
- 2:44–4:44 pm Major · the moon passes underfoot · high activity
- 7:26–8:26 am Minor · moonset · medium activity
- 11:06 pm–12:06 am 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.

Water depth
Drops off fastThe bottom drops off fast: the water is 33 ft deep just 190 ft from shore. It reaches 164 ft at 1.9 mi.

- 16 ft deep80 ft
- 33 ft deep190 ft
- 66 ft deep0.45 mi
- 164 ft deep1.9 mi
For fishing, swimming and diving
- Shore fishing. Deep water close in: about 35 ft just 330 ft out. Good for casting from rocks, jetties or the beach itself; current and surf hit harder here.
- Swimming. The bottom drops quickly near the shore and you are soon out of your depth. Keep an eye on kids and weak swimmers.
- Diving. Shore diving works here: 33 ft at 190 ft and 66 ft at 0.45 mi from shore.
Rough estimate: here the data comes in cells of about 0.3 mi and misses details near shore (rocks, sandbars, small coves).
