As its name suggests, Iceland's climate is cold, but not as cold
as might be expected because of the passing warm waters of the Gulf
Stream, which regulate the climate. The summer temperatures in
Reykjavík range from 41°F (5°C) at night to as high as 77°F (25°C)
during the day. The average January temperature is 31°F (-0.5°C).
The south is the wettest part of the country, but snow is rare.
Coastal areas tend to experience winter gales and are generally
windy. During the summer months there is almost continuous
daylight; early spring and late autumn feature long twilights. From
mid-November until the end of January, in the darkness of winter,
the opposite is true, with the country only experiencing a few
hours of daylight each day. The Northern Lights are often visible
in autumn and early winter.
