The weather in Iceland is changeable and unpredictable, and the scenery in different seasons is very different. Iceland winter is basically from October to April, so ice cave activities generally start from November to March. October can also be regarded as autumn, and April and May are barely considered to be spring. Summer is generally considered to be 6, 7, and 8 months. Summer temperatures are generally more than 10 degrees, less than 20 degrees. Although it doesn't snow, it doesn't mean there is no storm, and it's not too new to snow in June. Occasionally there will be. For example, in summer (June-August), the sunshine is not too cold (Iceland is rarely 20 degrees, but summer can be at least 5 to 10 degrees, not too cold), from the weather and sunshine. They all have advantages. Iceland in the summer is almost never falling, and it is easy to travel in the most beautiful summer. The scenery is bright and the colors are bright. The mountain roads will be open in the summer and there are more areas to explore. Inland highlands, western fjords, self-driving, hiking, cycling and other ways to travel, you can also meet the cute Puffin. But tourists will be relatively more, there is no blue ice hole project, and there is no aurora.
