Sumburgh tide times

Sumburgh Head is the southernmost point of the Shetland Mainland, an exposed sandstone headland 45 km south of Lerwick where the tides of the North Sea and the Atlantic margins converge. The spring range at Sumburgh is approximately 2.0 m — slightly larger than Lerwick's 1.8 m, reflecting the more exposed southern position. The tidal current off the headland is the dominant feature: the Sumburgh Roost, the tidal race south of the head, runs at 5–7 knots on spring tides and produces breaking seas and steep wave trains even in calm weather. In wind-against-tide conditions, the Roost is one of the most dangerous stretches of UK coastal water for small craft.

The RSPB Sumburgh Head reserve occupies the clifftop above the lighthouse, and from May through early August it holds one of the most accessible puffin colonies in Britain. The puffins nest in burrows on the short-cropped clifftop turf and walk to and from their burrows within a few metres of the viewing path. At peak season (mid-June), 20,000+ puffins are present on the headland. The birds are accustomed to people and approach within 2–3 metres — telephoto lenses are unnecessary, which is unusual for Atlantic seabird photography. The cliffs below the puffin colony also hold guillemot, razorbill, kittiwake, and fulmar, visible from the clifftop at close range.

Sumburgh Airport, adjacent to the headland, is Shetland's main airport and the helicopter base for North Sea oil platform operations. The airport occupies the flat ground between the headland and the Loch of Spiggie; its operational history is intimately connected to the oil industry. Loganair flights connect Sumburgh to Edinburgh, Aberdeen, Glasgow, Bergen, and Faroe; the airport is the main transport link for Shetland. The airport perimeter fence runs within a few hundred metres of the puffin colony — the contrast between industrial aviation infrastructure and nesting seabirds is one of the more unusual juxtapositions on the British coast.

Jarlshof, the archaeological site immediately south of the airport on the shore of West Voe of Sumburgh, is among the most significant ancient settlements in Scotland: 3,000 years of continuous occupation from Bronze Age through Neolithic, Iron Age, Viking, and medieval periods are visible in a single excavated site. The Viking longhouse foundations, the broch tower, and the Bronze Age oval houses are all present within a compact area above the beach. The site is managed by Historic Environment Scotland and open to visitors; the adjacent Shetland Museum annex provides context.

For shore anglers, the rock platforms on the east side of Sumburgh Head at low water produce pollock, coalfish, and large wrasse. The tidal race south of the head creates feeding aggregations on the eddy lines — predatory fish concentrate where the fast current meets the slack water behind the headland. Night fishing with large lures or mackerel strip is the technique for pollock and coalfish in the 45 minutes either side of the tidal slack, when the race briefly moderates. The east coast platform rocks are only accessible at low spring water; check the predicted low and allow enough time to climb back before the flood covers the lower ledges.

The bay of West Voe of Sumburgh, south of the airport and north of Sumburgh Head, provides sheltered anchorage for small craft in southwest through northwest winds. The bay is exposed to the southeast; in southeasterly conditions the anchorage becomes untenable and vessels must proceed north to Lerwick. Tidal streams in the bay are 0.5–1.0 knots, manageable for anchored vessels.
