The weather in Reykjavík is notoriously unpredictable - one minute the sun may be shining on a nice summers day, the next it may change into a windy, rainy autumn. On a few days of the year the city has only about 4 hours of sunlight, but in the summertime Reykjavik is light for 24 hours.
When it started to develop as a town in the 18th century, Reykjavík had already been inhabited for almost a thousand years. It is believed that Iceland’s first settler, Ingolfur Arnarson, made his permanent residence here in 874. Upon arrival he saw steam rising from hot springs near a cove and consequently named the bay "Reykjavik" translated as “The Steamy Bay” after its boiling geysers and bio-thermal springs.
Thus it’s no surprise that the Blue Lagoon is Iceland's most popular tourist attraction. The water in the lagoon is never lower than 37 degrees Celsius making it the perfect relaxing getaway from the cold, moreover the high mineral content in the water is extremely healthy and very good for your skin.
Reykjavik is a very green city. Many wells have been created so that hot water is pumped directly from the ground into all houses in the greater capital area providing inexpensive central heating resulting in a smoke-free city. Although about 80% of Iceland's territory is uninhabited, Icelandic waters are very rich in fauna - more than 20 species of whale have been recorded here and whale watching is an extremely popular attraction in Reykjavik.
Another thing that makes the country such a popular tourist hub is the Aurora Borealis, or Northern Lights, that appear in a variety of colors and shapes and can be experienced in Iceland during the winter.
Overall it should be noted that due to its young age and rapid expansion in the late 20th century, Reykjavík is very different from the other Nordic capitals but has its own charm, it is a very unique city with incredible nature.
