Summers from June - August is the best time to visit Iceland because of the warm, balmy weather and the phenomenal Midnight Sun. It is indeed a spectacular time, with pleasant temperatures and prolonged daylight hours that enable you to see as much as you can.
Despite the unpredictable weather, Iceland has four distinct seasons. The country of mystical landscapes and awe-inspiring vistas has a somewhat misguided image of being a constantly freezing destination. In reality, it experiences a much milder climate, with no drastic changes between the summer and winter temperatures. Iceland is situated on top of one of Earth’s many hot spots, owing to which, the country boasts of phenomenal geothermal activity. It has an abundance of hot springs, mud pools, geysers and volcanoes. If you’re looking for a combination of moderately good weather and lesser crowds, then you can consider early spring or late fall. Guaranteed darkness and cold, clear nights during winter make Iceland an ideal place to see the aurora borealis. The best time to catch the Northern Lights would be from late September through late March. This is the time when most music and arts festival takes place in Reykjavik.
