Tides in Harthaven
Today's high and low tides
- ▲ High tide 1:23 am 1.9 ft · coef. 92
- ▼ Low tide 6:32 am -0.2 ft
- ▲ High tide 1:48 pm 2.3 ft · coef. 90
- ▼ Next low tide 7:31 pm -0.1 ft
↓ Falling The tide is falling. 38 min to low tide at 7:31 pm.
Tide coefficient 92 for the 1:23 am high tide and 90 for the 1:48 pm high tide. Spring tides. The water rises and falls 2.6 ft between the highest high and the lowest low: an average 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 June 16 (2.5 ft) and the lowest, on December 25 (-0.5 ft).
Semidiurnal: two high and two low tides a day, of similar height.
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 28 (coefficient 94, 2.6 ft range). The smallest, from October 18 to 19 (coefficient 36, 0.8 ft).

Where this tide comes from
Tides from the Oak Bluffs station (NOAA), 1.1 mi from Harthaven. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Newport reference station with the official corrections.

The sea at Harthaven
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.3 ft
- Significant0.6 ft
- Highest expectedHighest1.2 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 1.2 ft. Before heading out, expect waves of up to 1.2 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 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 Friday 30: 2.1 ft with a period of 3 s, from the southwest (slight).
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.

Your diving day at a glance
The best window, 11:50 am to 2:30 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also worth a look from 7:10 am to 9:10 am, with slack water at low tide, little swell and light wind, though with 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.
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 226,429 mi away and looks 32′ 47″ across.
Solunar periods
Today's activity: high- 1:16–3:16 am Major · the moon passes overhead · high activity
- 1:48–3:48 pm Major · the moon passes underfoot · high activity
- 9:50–10:50 am Minor · moonset · medium activity
- 6:42–7:42 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. Shallow, gradual bottom (16 ft at 1.1 mi): cast far from the beach and fish the high tide, when there is more water close in.
- Swimming. A very gentle way in with plenty of shallow water, good for kids. At low tide the water can be far out.
- Diving. Shallow: the water doesn't reach 33 ft within 3.1 mi. For deeper dives, take a boat farther out.
Inside bays, estuaries and harbors the bottom changes a lot from spot to spot (channels and shoals): use this only as a rough guide.
