September in Iceland marks the meteorological beginning of autumn. Temperatures typically range from 4C to 10C (39F to 50F). Expect a mix of sunshine, rain, and increasingly frequent wind. The northern lights may begin to appear, adding a magical element to the darkening skies. This transitional month offers a unique blend of summer’s lingering warmth and the approaching chill of winter.
Visiting Iceland during this period presents several advantages. The dwindling crowds mean lower prices for accommodations and tours compared to peak summer months. The changing landscape, with its vibrant autumnal hues, provides breathtaking scenery for photographers and nature enthusiasts. Additionally, the cooler temperatures are ideal for hiking and exploring the rugged terrain. Historically, September has been a time of harvest and preparation for the long winter ahead, a rhythm still felt in the local culture.
