Tides in Harwich Port
Today's high and low tides
- ▲ High tide 2:40 am 3.9 ft · coef. 84
- ▼ Next low tide 8:14 am 0.1 ft
- ▲ High tide 2:51 pm 4.5 ft · coef. 82
- ▼ Low tide 8:54 pm -0.3 ft
↓ Falling The tide is falling. 4 h 17 min to low tide at 8:14 am.
Tide coefficient 84 for the 2:40 am high tide and 82 for the 2:51 pm high tide. Average coefficient. The water rises and falls 4.8 ft between the highest high and the lowest low: a small 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 May 18 (4.7 ft) and the lowest, on December 25 (-0.6 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 29 (coefficient 85, 4.9 ft range). The smallest, from October 18 to 19 (coefficient 48, 2.5 ft).

Where this tide comes from
Tides from the Wychmere Harbor station (NOAA), 0.7 mi from Harwich Port. Times and heights are its predictions. It is a NOAA subordinate station: its times and heights come from the Boston reference station with the official corrections.

The sea at Harwich Port
Sea stateSea state: smooth
The waves you may find
- Most commonMost common0.6 ft
- Significant1.2 ft
- Highest expectedHighest2.5 ft
One wave in seven is higher than the significant height, and about 3 times a day one reaches 2.5 ft. Before heading out, expect waves of up to 2.5 ft.
Wind on the coast and offshore
The model doesn't separate offshore wind here: it's the same as on the coast.
Onshore wind. The coast faces south and the wind blows straight in from the sea: more surf and backwash at the shore, and bait and boats drift toward land.
Wave height, next 7 daysWaves, next 7 days
Waves stay much the same all week. The biggest waves arrive on Wednesday 4: 2.4 ft with a period of 4 s, from the south-southwest (slight).

Your diving day at a glance
The best window, 12:30 pm to 1:30 pm, combines little swell, weak current and the sun high, though with moderate wind. Also worth a look from 6:40 am to 7:30 am, with slack water at low tide, little swell, light wind and weak current, though with low light.
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 226,746 mi away and looks 32′ 44″ across.
Solunar periods
Today's activity: medium- 2:18–4:18 am Major · the moon passes overhead · high activity

- 11:00 am–12:00 pm Minor · moonset · medium activity
- 7:41–8:41 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 0.75 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.
