South winds generally lead to little or no precipitation in the north, which is associated with higher temperatures. North winds bring clouds with them, resulting in colder and wetter weather in the north of the country, while the south remains sunnier and milder. The same applies to westerly or southwest winds, which bring warmer weather to the east. The opposite is the case when the wind comes from the east: it leads to cold and precipitation in the east and better weather in the west of Iceland. This is the result of the foehn wind : moist, cold air rises near the highlands, condenses and falls as rain over the highlands, while warmer, drier air falls down into the valley on the other side. The temperature difference can be 10 °C or more.
