Thurso East.

A wave made of flagstone

The reef is made of Caithness flagstone, the same layered rock that has paved streets from Thurso to Paris, according to Wikipedia. The layers form ledges and steps that shape the wave as swell passes over them. The result is a long right-hand wall that peels from an outside peak towards the river mouth, with sections that stand up and tube on the right combination of tide and swell.

Surf-Forecast describes Thurso East as an exposed point break and rates it five out of ten, fairly consistent and able to work at any time of year. It also emphasises that there is no beach break here, which means every ride starts on the reef and ends in deeper water near the rocks. The fall line is predictable once you have watched the wave break, but it is not forgiving of mistakes.

Reading swell, wind and tide

The best swell direction is north-north-west, and the best wind is south-east offshore, according to Surf-Forecast. The page says the best tide is mid tide on the rise. Because the northern coast of Scotland faces the open Atlantic, it receives swells from many storm tracks, and the wave can work in all seasons. Late summer and autumn swells are often kinder than midwinter storms, with lighter winds and slightly warmer water.

Winter statistics on the page, for February, show about 24 percent clean, 49 percent blown out and 27 percent too small. The wave is demanding in wind, and a direct onshore blow will wipe it out. Surf-Forecast gives a sea temperature of about 12 degrees Celsius at the time of writing, with a winter wetsuit, hood, gloves and boots recommended. In January and February, expect much colder water.

Who should not surf Thurso East

Thurso East is for experienced surfers who are comfortable in cold, powerful waves over a shallow reef. The rocks are close to the surface, and the Surf-Forecast page warns surfers to avoid them. Cold water adds to the risk because it reduces strength and judgement, and wind chill can be severe even in summer. Do not surf here alone, and do not attempt the wave if you have not surfed in cold water with a thick wetsuit.

Beginners and improvers will find easier conditions on the beach breaks elsewhere on the north coast, including the beach next to the reef. The line-up at Thurso East is also competitive. Surf-Forecast says it can get crowded when working, and local surfers expect visitors to show patience and to respect priority. Dropping in on a wave that a local is riding will not go down well.

Access and viewing

Thurso is the northernmost town on the British mainland, according to Wikipedia, and the reef lies on its eastern edge at the river mouth. Wick airport is about 29 kilometres away on Surf-Forecast's figure, and Kirkwall in Orkney is about 52 kilometres. The town is also served by a railway line from Inverness and by roads from the south. The A9 and A836 meet at Thurso.

The view of the wave from the cliff and the castle grounds is excellent. You can see the line-up, count the people in the water and judge the size of the sets. Be careful on wet grass and wind-exposed edges, and check for any restrictions on the castle land. Parking and walking routes change, so confirm the current arrangements locally or with a surf shop.

History and neighbouring waves

Thurso East entered the surfing spotlight in 2006 when it hosted the first O'Neill Highland Open, a WQS event won by British surfer Russell Winter, according to Wikipedia. O'Neill sponsored an international contest at the reef until 2011, later called the Coldwater Classic, and ended the sponsorship in 2012. Other nearby breaks on Surf-Forecast include Thurso Beach, Thurso Reef, The Spur and Murkle Point. The Thurso destination guide covers the wider coast.
