Iceland's mild climate stems from the Gulf Stream and the warm ocean currents from the Gulf of Mexico.
The weather is also affected by the East Greenland polar current curving south-eastwards round the north and east coasts.
The days are very short in mid-winter, and for two to three months in summer there is continuous daylight in Iceland; while early spring and late autumn enjoy a long twilight.
Average temperatures for winter remain around 35°F (1°C) for much of the island, with summer temperatures reaching the mid-50's (13°C).
