Tides in Marblehead
Today's high and low tides
- ▲ High tide 12:57 am 9.4 ft · coef. 85
- ▼ Low tide 6:54 am 0.0 ft
- ▲ High tide 1:08 pm 11.0 ft · coef. 86
- ▼ Next low tide 7:34 pm -1.2 ft
↓ Falling The tide is falling. 44 min to low tide at 7:34 pm.
Tide coefficient 85 for the 12:57 am high tide and 86 for the 1:08 pm high tide. Average coefficient. The water rises and falls 12.2 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 25 (11.5 ft) and the lowest, on May 18 (-1.7 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 come from October 27 to 29 (coefficient 86, 12.2 ft range). The smallest, from October 18 to 19 (coefficient 46, 5.7 ft).

Where this tide comes from
Tides from the Salem station (NOAA), 1.9 mi from Marblehead. Times and heights are its predictions.

The sea at Marblehead
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.5 ft
- Significant1.0 ft
- Highest expectedHighest2.0 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.0 ft. Before heading out, expect waves of up to 2.0 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 stay much the same all week. The biggest waves arrive on Wednesday 28: 1.4 ft with a period of 6 s, from the east-northeast (smooth).
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.

- Light: First light 6:43 am · sunrise 7:12 am · sunset 5:42 pm · last light 6:11 pm
- Tide: high 12:57 am (9.4 ft), low 6:54 am (0.0 ft), high 1:08 pm (11.0 ft) and low 7:34 pm (-1.2 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.

- Night dive: dark from 6:11 pm. Waning gibbous (91%), rising at 7:09 pm: a bright night.
Your diving day at a glance
The best window, 12:10 pm to 2:10 pm, combines slack water at high tide, little swell, light wind, weak current and the sun high. Also good from 6:40 am to 8:10 am, with slack water at low tide, little swell, 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.
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- 1:17–3:17 am Major · the moon passes overhead · high activity
- 1:49–3:49 pm Major · the moon passes underfoot · high activity
- 9:56–10:56 am Minor · moonset · medium activity
- 6:39–7:39 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. About 7.2 ft of water 330 ft out: long casts help, and so does a rising tide, which brings fish closer in.
- Swimming. The water gets deeper little by little, but a few dozen yards out you can no longer stand.
- Diving. Shallow: the water doesn't reach 33 ft within 0.8 mi. For deeper dives, take a boat farther out.
There is little open water ahead: in a cove or small bay, cells of about 300 ft cannot show the bottom well near the rocks. There is land ahead (an island, a headland or the far shore) 0.8 mi out. The profile is turned slightly from the coast so it does not run into an island or a headland.
