East of Burray: High water is 30 minutes after high water at Wick
Old Head, South Ronaldsay: The tidal stream here flows south south-west starting 5 hours and 5 minutes after high water at Aberdeen reaching a maximum speed of 6 knots at springs. The stream runs for 9 hours. There is no north-going stream. A race forms east and south-east of the Head from around 6 hours and 10 minutes before high water at Aberdeen until 2 hours and 20 minutes before high water at Aberdeen.
East coast of South Ronaldsay: The tidal stream here flows south starting 6 hours and 10 minutes before high water at Aberdeen reaching a maximum speed of 1 knots at springs. The stream runs for 9 hours. There is no north-going stream. The stream is stronger to the south of the island than the north, but does not exceed 1 knot until near Old Head.
Around Burray: Tidal streams around the coast of Burray are generally weak.
Burray Ness: Tidal streams at Burray Ness are weak, but an onshore wind can produce large and unpredictable waves here.
Holm Sound: Flows are weak within the Sound.
Rose Ness: The north-east going stream begins at 5 hours and 20 minutes before high water at Aberdeen. The south-west going stream begins at 40 minutes after high water at Aberdeen. The flow reaches a speed of 1.5 knots at springs. The area can be rough in wind against tide conditions.
South East coast of Mainland: Between Rose Ness and Copinsay Pass streams are weak.
Copinsay Pass: The east north-east going stream begins at 2 hours and 5 minutes before high water at Aberdeen. The west south-west going stream begins at 4 hours and 20 minutes after high water at Aberdeen. The flow reaches a speed of 3 knots at springs. The Pass is shallow and standing waves, boils and a clear eddyline form. Conditions can be challenging when wind opposes tide.
Between Copinsay and Horse of Copinsay: The stream running south along Deerness splits near the Point of Ayre, dividing around Copinsay with one arm running through the Copinsay pass and the other between Copinsay and Horse of Copinsay. The south south-east going stream begins at 4 hours and 20 minutes after high water at Aberdeen. The north north-west going stream begins at 2 hours and 5 minutes before high water at Aberdeen. The flow reaches a speed of 4 knots at springs. A race can form to the east of the Horse of Copinsay and there may be rough water off North Nevi and South Nevi.
Point of Ayre to Mull Head, Deerness: The flow is continuously northwards due to an eddy formed behind Mull Head. The stream, and associated small eddies, can be felt around the Skail Skerries, where conditions may be rough when a northerly wind opposes this stream.
Burray barrier north: (ND 474 983) g Small layby at the south end of Churchill Barrier Number 3, from which beaches on either side of the Barrier may be accessed. There is more space to park at the north end of the Barrier.
Glimps Holm south: (ND 473 987) g Good sized layby close to the north end of Churchill Barrier Number 3 from which a path leads 50m down to a beach on the east side of the barrier. The sea to the west can be accessed through a gate leading to a small beach.
Lamb Holm south: (HY 482 000) g Parking area at the north end of Churchill Barrier Number 2, from which the sea on the east side of the barrier can be easily accessed. Accessing the sea to the west may require a short walk up the road (or the use of a pull off near the pier to the north) to avoid a carry across large boulders.
Lamb Holm north: (HY 485 007) g Parking space for one or two vehicles at the south end of Churchill Barrier number 1. More parking space by the Italian Chapel just to the east, but it may be easier to use the parking at the south side of the island.
Sandside Bay: (HY 589 069) g May be possible to drive down a small track to a parking area by the beach, but it has been reported that a gate across this track is sometimes locked. It may also be possible to park and access the sea near St. Ninian's Kirk, down a short road off the main road just to the south where it turns abruptly west.
