East coast Suffolk Ebb
Orford Ness from Aldeburgh: a low-range coast with a river-sized current
The Suffolk coast has barely three metres of tide and a current that behaves like a much bigger estuary. Orford Ness is a 10 mile shingle spit with a river behind it, a nature reserve on it, and a set of tidal narrows where the stream runs harder than anything else on the east coast south of the Humber.

Why three metres of tide still matters
The range here is small, so paddlers assume the currents are small too. They are not. The Ore, the Alde and the Butley River all empty through a single narrow mouth at Shingle Street, and the whole volume of that estuary system passes through a gap that is under 200 m wide at half tide.
On a 3.2 m spring the ebb in the narrows reaches 2.4 knots. On a 1.1 m neap it still runs at about 1.2 knots. The practical difference between the two is whether you can make ground at all against it; on springs, paddling a loaded boat into a full ebb stream here takes you nowhere useful.
Rounding the Ness
From Aldeburgh the paddle south is 4 nm of open shingle beach with a shore break in any wind from the southeast. There is one point where the beach is interrupted: the mouth of the Alde at the north end of Orford Ness, where the falling tide pours out over a shoal and produces a standing wave that is visible as a line of white water for a quarter of a mile offshore.
Round that shoal at least 400 m offshore, or go through it at slack. The standing wave is not the danger; the danger is the eddy on the inside of it, which will spin a boat and set it sideways onto the shoal before you can react.
Inside the river
Once inside the mouth the water changes entirely. The Alde is a wide, shallow, reed-fringed river with no swell and a gentle current, and it runs for 8 nm inland to Snape. Orford quay is 2 nm in and has a hard, a pub and a fresh water tap, which makes it the obvious lunch stop.
The Butley River branches off to the west and is the quieter arm. It dries to mud at low water, has a seal colony at its head, and is closed to landing on the north bank between March and August for nesting. Do not take a shortcut across the inside of the Ness: the whole area between the river and the sea is a shingle and marsh nature reserve with no landing allowed.
Getting back out
The key decision of the day is the exit. If you are leaving the river on the ebb, you will be pushed hard out through the narrows and it is an exhilarating ride. If you are leaving on the flood you will be paddling against 1.5 to 2 knots through the same gap, and the return leg along the open beach to Aldeburgh then has to be done in whatever wind has built.
The sensible pattern is out on the ebb, lunch at Orford, back out through the narrows at low water slack, and north up the beach on the first of the flood. That gives you a favourable stream in both directions and keeps the exposed beach section at the calmest part of the tide.
Plan table
Before departure
- 01
Find low water slack at Shingle Street, not high water
The exit window is built around low water slack, which is the only time the narrows are manageable in both directions.
- 02
Check wind against tide for the beach leg
A force 4 southeast against an ebb makes the Aldeburgh beach leg a genuine slog.
- 03
Confirm landing rules at Orford Ness
The Ness is a National Trust reserve; landing is restricted to the quay and a few marked points.
- 04
Carry a towline
In 2 kt of stream a tired paddler cannot hold station and needs to be taken in tow rather than shouted at.
En route
- 01
Round the Alde shoal 400 m offshore
The standing wave line at the river mouth extends a quarter of a mile to seaward on springs.
- 02
Keep out of the inside eddy at the Ness north end
The counter-current there sets onto the shoal and has caught out more than one group.
- 03
Log the exit time with a shore contact
If you miss low water slack the exit becomes a two-hour wait at Orford quay.
- 04
Keep west of the channel in the Butley arm
The east side dries early and the mud is soft and deep.
Key numbers
- 9.8 nm round trip including the river section, 4 to 6 hours.
- Exit window: low water slack at Shingle Street. Be at Orford quay an hour before it.
- Ebb springs reach 2.4 kt in the narrows; the flood is harder to paddle against.
- Wind limit 12 kt; the return along the open shingle beach is the exposed part.
- Landing on Orford Ness itself is restricted; the quay and the Butley arm are the options.
Bail-outs
- B1 Orford quay, inside the river, all states of tide
- B2 Shingle Street, 2 nm south of the Ness, a straightforward beach landing
Return leg：Return north on the first of the flood with the Ness to your left. Do not attempt to round the Ness against a full ebb spring stream, which stands up over the shoal at the north end.
