Orkney is an archipelago of 70 islands lying just off the northern tip of mainland Scotland, where the Atlantic Ocean collides with the North Sea. The landscape is windswept, treeless in most places, and strikingly ancient: 5,000-year-old Neolithic villages, stone circles, and burial cairns sit alongside towering sea cliffs that host thousands of breeding seabirds each summer. This is a place shaped by Norse heritage, wartime history, and a fiercely proud local culture, from the 12th-century St Magnus Cathedral in Kirkwall to the Italian Chapel built by prisoners of war, to the distillery tours at Highland Park. Orkney rewards visitors who come for the long light, the wildlife, and the sense of standing at the edge of something very old.
The best time to visit Orkney is late July, when you'll hit the sweet spot of the islands' brief summer season. Days stretch past 17 hours of light, seabird colonies (including puffins) are still active along the cliffs, and the St Magnus International Festival and Stromness Shopping Week will have just wrapped up, leaving the islands in full summer swing but slightly less crowded than the August peak. Highs reach 60.2°F (15.7°C) with the least rain of the year, and inter-island ferries run their fullest schedules. If you'd rather pair your visit with a specific event, late May brings the Orkney Folk Festival in Stromness, and September delivers the Orkney International Science Festival alongside thinner crowds and lower accommodation costs.
Spring in Orkney Islands, the United Kingdom
Spring arrives slowly on Orkney. March can still feel like winter, with morning lows near 36.9°F (2.7°C) and stiff winds off the North Sea. But the days are lengthening rapidly, climbing from about 12 hours in March to nearly 17 by the end of May, and that shifting light transforms the landscape. Hen harriers begin their spectacular sky-dancing courtship displays over the moorlands, and the first puffins return to cliff-face burrows by late April. Precipitation is relatively modest for Orkney, with roughly one to four wet days per month, making it one of the drier stretches of the year.
The festival calendar kicks off in April with the Blues Festival and St Magnus Day, when Orkney flags fly from public buildings around Kirkwall. Late May brings the Orkney Folk Festival, a four-day celebration that fills the pubs and venues of Stromness with traditional music from local and international performers. The Orkney Nature Festival also runs in May, with guided walks, snorkelling safaris, and photography workshops across the islands. Afternoon highs climb to 50.9°F (10.5°C) on average, so layering is essential: a windproof jacket, fleece, and a warm hat will serve you well at clifftop viewpoints.
Tourism picks up through the season, with May approaching summer-level visitor numbers. Accommodation is easier to find and often cheaper than in peak months. This is also an excellent time to explore the Heart of Neolithic Orkney UNESCO World Heritage Site, including Skara Brae and the Ring of Brodgar, before summer coach tours arrive in force.
Summer in Orkney Islands, the United Kingdom
Summer is when Orkney comes fully alive. The sun barely dips below the horizon in June, giving you over 18 hours of usable daylight, and even in late August you'll have more than 15 hours to explore. Seabird colonies reach peak activity along the cliffs at Marwick Head, Westray, and the Brough of Birsay, where puffins, guillemots, gannets, and kittiwakes crowd every available ledge. Seals haul out on rocky skerries around the coast, and orca sightings are reported from clifftops throughout the summer months. Afternoon highs average 60.2°F (15.7°C) with overnight lows of 45.1°F (7.3°C), comfortable enough for full days outdoors but still cool enough to warrant a fleece for evening walks.
June hosts the St Magnus International Festival, a prestigious six-day celebration of classical music, theatre, dance, and literature set against the midsummer light. Stromness Shopping Week, one of Orkney's longest-running community festivals, fills the town with street entertainment, races, and live music. In August, the Orkney County Show takes over Kirkwall with livestock judging, local produce stalls, and evening dances, while the charming Festival of the Horse and Boys' Ploughing Match on the beach at South Ronaldsay is a tradition found nowhere else. This is also peak season for the three-hour walk to the Old Man of Hoy, the 137-metre sea stack on the island's western coast. Early August brings the warmest conditions of the year, with highs nudging 62.3°F (16.8°C) and lows around 46.8°F (8.2°C). Rain is at its lightest, with wet conditions on roughly four to five days per month.
August is the busiest month on the islands, and accommodation books up fast. Reserve ferries and lodging well ahead. A rental car or bike is the best way to cover the Mainland's key sites and reach ferry terminals for island-hopping to Hoy, Rousay, or Westray. Pack layers, waterproofs, and sunscreen: the wind is constant, but the long evenings reward it.
Fall in Orkney Islands, the United Kingdom
As summer's seabird colonies thin out, fall brings a different kind of wildlife spectacle. Grey seals come ashore to pup from October into November, and you can watch fluffy white pups nursing on remote beaches. Migratory geese, swans, and ducks arrive from the north, replacing the departed puffins and guillemots. The Orkney International Science Festival fills Kirkwall venues in September with talks on everything from archaeology to astrophysics. September also brings the Orkney Rock Festival and the Taste of Orkney Food Festival, which showcases the islands' local seafood, cheeses, and craft beverages.
Highs still average a manageable 53.9°F (12.2°C), but lows drop to 40.8°F (4.9°C) and the wind starts to reassert itself. Showers become more frequent, with wet weather on roughly four to six days per month by November. Daylight fades noticeably: September still offers about 13 hours, but by late November you're down to under 8 hours, so plan your sightseeing around the shorter window. The archaeological sites, including Maeshowe, Skara Brae, and the Stones of Stenness, are far quieter now, and you can explore them without competing for space.
Visitor numbers drop sharply after September, and accommodation prices follow. This is a good season for travelers who prefer solitude and don't mind layering up. A serious windproof outer layer and waterproof boots become essential. On clear autumn nights, look north: the Northern Lights, known locally as the Merry Dancers, occasionally put on a display over the islands.
Winter in Orkney Islands, the United Kingdom
Winter strips Orkney down to its essentials: stone, sea, wind, and sky. Days shrink to barely 6 hours in December, with the sun not rising until around 9:00 AM and setting by 3:12 PM. Temperatures hover with highs around 44.9°F (7.2°C) and lows near 34.4°F (1.3°C), and gale-force winds are common, especially in January and February. Precipitation is persistent, with wet weather on roughly four to six days per month, and January is the wettest month of the year.
For all that, Orkney's winter has a wild beauty and one truly unmissable tradition: the Kirkwall Ba'. Played on Christmas Day and New Year's Day, this mass street game sends teams of Uppies and Doonies surging through the flagstone streets of Kirkwall, battling for control of a handcrafted leather ball. The Yule Log Pull in Stromness on Hogmanay adds to the festive chaos. Large flocks of wildfowl gather on the lochs, and sea ducks like Long-tailed Ducks and Eiders ride the coastal waters. Keep your eyes open for rare wintering raptors.
Many visitor services, ferry routes, and accommodation options are limited or closed entirely during winter. If you do come, plan carefully and confirm availability in advance. Warm, windproof layers, thermal base layers, and waterproof everything are non-negotiable. The reward is an Orkney that feels raw, intimate, and entirely your own.

Travel Tips & Safety for Orkney Islands, the United Kingdom
Orkney is reached by ferry or air. Pentland Ferries operates the quickest crossing, roughly an hour from Gill's Bay on the Scottish mainland to St Margaret's Hope on South Ronaldsay. NorthLink Ferries also sails from Scrabster to Stromness. Flights connect Kirkwall Airport with Edinburgh, Glasgow, Aberdeen, and Inverness. Once on the islands, a rental car is the most flexible option; some of the outer islands are linked to Mainland by the Churchill Barriers, letting you drive between Lamb Holm, Burray, and South Ronaldsay. Inter-island ferries and the famously short Westray-to-Papa Westray flight connect the more remote islands.
Orkney is one of the safest travel destinations in the UK, with very low crime rates. The main hazards are environmental: coastal winds can be fierce and unpredictable, so stay well back from cliff edges, especially at seabird colonies. Tidal islands like the Brough of Birsay are only accessible at low tide, and the water returns quickly, so always check tide tables before crossing. Bring seasickness remedies if you're sensitive, as the Pentland Firth crossing can be rough in bad weather.
