Iceland Holidays in September

September is the mildest point of the Icelandic autumn, and the warmest spots are usually the sheltered southwest and the capital area rather than the exposed highlands.

• Vik: Vik sits on the south coast along the Ring Road, a village that benefits from its position out of the strongest interior winds. It is one of the wettest places in Iceland, so September rain is likely and you should expect damp conditions even when the sun appears. We suggest it for travellers who want a coastal base on the Ring Road without chasing the highest temperatures, and who are happy to plan around showers.
• Reykjavik: Reykjavik is the capital and largest city, and its harbour and compact centre hold more warmth in September than the open countryside. The city has a dense cluster of cafes, restaurants and museums that make it easy to stay comfortable between outings. We recommend it as the most reliable base for travellers who want milder evenings and a short walk to almost everything. Explore our Reykjavik holidays for flight and hotel options.
• Reykjanes Peninsula: The Reykjanes Peninsula lies close to Keflavik Airport and holds the Blue Lagoon, a geothermal spa fed by seawater heated naturally. Its lava fields are exposed to Atlantic winds, so the air can feel brisk even when the water is warm. We point travellers here for a short stay near arrival or departure, when a warm soak after a long flight is the main priority.
• Golden Circle: The Golden Circle is a route of about 300 km starting from the capital, taking in the national park with its famous rift valley, the Geysir area and Gullfoss waterfall. Mild weather makes the route comfortable for a full day, though the shorter September daylight means an early start is wise. We recommend it as a sheltered day out for travellers wanting variety without long, exposed drives.
• Akureyri: Akureyri is the largest town in northern Iceland, set on the long Eyjafjordur and sheltered by surrounding mountains. September here is cooler than the south but often calmer, and the town centre is a short walk from the harbour. We suggest it for travellers who prefer a gentler northern base and are willing to trade a little warmth for quieter streets. Browse these holidays with a northern stay. It is exactly the brief our Iceland holidays deals are built around.
