The best time to visit Iceland for your cruise season

June through August is Iceland’s busiest cruise period, and the appeal becomes obvious once you step ashore. Temperatures are generally at their mildest for the year and daylight seems reluctant to leave. Late June into early July brings the most extreme version of this, when the sun skirts the horizon and true darkness never really settles in.

Long days for exploring ashore

For guests, that extra daylight changes the feel of a day ashore. Waterfalls remain visible deep into the evening, green hills hold their color under a low sun and summer outings can make full use of later sunshine.

Summer also suits hiking and excursions that depend on easier road access. Iceland’s F-roads (mountain routes that lead into the country’s interior) generally open only during the warmer months, with exact opening dates depending on snowmelt and other road conditions. That can put more remote valleys, volcanic terrain and highland scenery within reach during the summer season.

May offers a quieter version of Iceland than peak summer. Days are cooler, visitor numbers tend to be lower and the landscape may still show traces of winter, though the days are already long and puffins have returned to the coastal cliffs.

Icelandic weather can change quickly regardless of season. A clear morning may turn cool and damp later in the day, late sunshine can create sudden warmth and coastal wind can come out of nowhere. Packing with flexibility in mind makes it easier to stay comfortable as conditions shift.

• Bring a waterproof outer layer - A wind-resistant jacket is useful even in summer, especially near waterfalls and along exposed stretches of coast.
• Dress in layers - A warm midweight piece gives you room to adjust as temperatures change throughout the day.
• Choose shoes for wet ground - Comfortable footwear with good traction will help you keep your footing on damp paths, uneven surfaces and various excursion stops.
• Pack for a cooler May - A hat and gloves are worth bringing for May sailings, when mornings and evenings can feel noticeably colder.
• Expect some movement at sea - North Atlantic conditions can vary, so guests who are sensitive to motion may want to pack motion sickness medicine.
• If you extend your stay, plan around the roads - Highland F-roads are seasonal, require a 4x4 vehicle and often include river crossings, and colder-weather driving takes more preparation. On your port day, Princess shore excursions handle the transportation.

Summer is Iceland’s busiest travel season, especially in Reykjavik and around heavily visited areas such as the Golden Circle. In July and August, expect more people at major viewpoints, geothermal sites and popular shore-excursion stops. May tends to feel less busy. For some guests, that extra breathing room is worth slightly cooler temperatures. Others prefer summer, when more visitor services are operating and the country feels fully geared toward long days outdoors. Geothermal stops such as the Blue Lagoon are especially busy in summer, and Princess’s Bathing in the Blue Lagoon excursion from Reykjavik handles the transportation.

Be aware that demand can also affect airfare and hotel rates for a pre- or post-cruise stay, with summer often commanding higher prices. That said, cruise fares vary by sailing, so don’t rely only on price when you’re deciding what season is the best option for your Iceland cruise.

Iceland changes from one coast to another. Princess itineraries can bring you into the country’s northern hub, compact harbor towns or the country’s capital, with the available excursions changing according to daylight and seasonal conditions.

Reykjavik

Reykjavik serves as a turn port on select itineraries, with cruise facilities within easy reach of downtown. From here, Princess excursions such as Best of the Golden Circle can reach geothermal areas, Thingvellir National Park and some of southwest Iceland’s best-known waterfalls. And if you’re researching things to do in Reykjavik, leave room to explore the city itself. Its restaurants, waterfront and cultural sites help fill a port day before or after a Princess excursion.

Akureyri

At Akureyri, the center of town is only a short walk from the harbor, so it’s easy to combine time in town with a Princess excursion into northern Iceland. Popular routes include Goðafoss, where a broad curtain of water drops across a horseshoe-shaped gorge, along with the geothermal landscapes around Lake Mývatn. Princess’s Best of Akureyri excursion covers the Mývatn area and Goðafoss in a full day. Summer’s long daylight hours are especially well suited to this part of the country, giving you more time to take in the open valleys and volcanic terrain.

Isafjordur

Isafjordur places you deep in the Westfjords, framed by steep mountains that rise straight from the water. The compact town sits close to the port, making it easy to wander on foot before or after an excursion. Isafjordur excursions venture beyond town toward fishing villages, narrow fjords and Dynjandi — a broad, tiered waterfall that spreads across the mountainside. Princess’s Best Of West Fjords - Dynjandi Waterfall & Villages excursion reaches it.

Grundarfjordur

On the Snæfellsnes Peninsula, Grundarfjordur is best known for Kirkjufell, the sharply peaked mountain that rises just outside town. Nearby excursions explore lava fields, black-pebbled beaches and views toward Snæfellsjökull, giving you a closer look at the peninsula’s volcanic landscape. Princess’s Best of Snæfellsnes Peninsula excursion visits Helgafell, Stykkishólmur, Arnarstapi and the black-pebbled beach at Djúpalónssandur.

Seydisfjordur

Seydisfjordur sits at the end of a long fjord in East Iceland, with colorful timber houses, a small harbor and the blue-painted Seyðisfjarðarkirkja church close to the pier. Waterfalls descend the slopes above town, while Princess excursions can take you farther into the surrounding countryside before you return to explore the compact center on foot. Princess’s Chasing Waterfalls excursion visits the region’s falls.

There is no single month that defines an Iceland cruise. The better choice is the one that matches what you want to carry home from the trip: the quieter, cooler days of May or hours of exploration under the lingering daylight of June through August. With Princess, every sailing gives you a chance to see how much Iceland can change from one port to the next.
