<\/span>Going to Iceland in September: quick answers<\/span><\/h2>\n\n

Is the weather nice in Iceland in September? Is this a good time to visit?<\/h3>\n\n

September is a month of transition in Iceland. Summer gives way to autumn, the colors change and the nights become dark again. Temperatures are dropping, but remain bearable, and tourist numbers are falling sharply. <\/p>\n\n

We consider September to be one of the most interesting months in which to visit Iceland: fewer people, landscapes tinged with red and orange, and the first real chances of seeing the northern lights. On the other hand, some mountain roads are gradually closing and the weather is becoming more capricious. It’s our favorite month of the summer!<\/p>\n\n

Travelling to Iceland in September: summary of conditions<\/h3>\n\n

Temperatures<\/strong><\/p>\n\n

Temperatures drop significantly in September. In Reykjavik and on the south coast, the thermometer fluctuates between 7\u00b0C (45\u00b0F) and 11\u00b0C (52\u00b0F) during the day. In the north, averages are slightly lower, around 6\u00b0C to 10\u00b0C (43\u00b0F to 50\u00b0F). Nights cool off markedly, dropping to 3\u00b0C to 5\u00b0C (37\u00b0F to 41\u00b0F) on the coast. At higher altitudes, night frosts become frequent from mid-September onwards.<\/p>\n\n

Crowds and prizes<\/strong><\/p>\n\n

September marks the end of the high season. Attendance dropped significantly, especially from the second week onwards. Popular sites in the Golden Circle and on the south coast remain popular. <\/p>\n\n

Opening conditions<\/strong><\/p>\n\n

Route 1 (circular road) remains open all year round. On the other hand, the F roads in the Hautes Terres gradually close during September, sometimes as early as the first week, depending on weather conditions. We recommend checking road conditions daily on road.is<\/a> if you plan to use mountain trails. Most museums, restaurants and hotels are operating normally. <\/p>\n\n

Length of day<\/strong><\/p>\n\n

The days shorten rapidly in September. At the beginning of September, the sun rises around 6 a.m. and sets around 8:15 p.m., providing around 14 hours of light. At the end of September, sunrise is around 7.15 a.m. and sunset around 6.45 p.m., i.e. around 11.30 a.m. This rapid shortening means that nights are now long enough to observe the Northern Lights.<\/p>\n\n
