After moving to Skagaströnd I became a weather enthusiast. The weather here has such clear patterns that I hadn’t realized before. In winter a north-east wind brings snow from the highlands that piles up behind every obsticle downwind, so houses that have front doors not facing the blizzard are covered with snow.
Not a single snowflake comes from the clouds above, it’s all carried by wind from the highlands above town, and it’s densely packed snow powder. Southern winds are more frequent in winter but they don’t have the same effect. They don’t tend to get as strong and do usually not involve snow storms.
Windroses are available for any area of Iceland https://vindatlas.vedur.is/ but they don’t have seasonality.
The winters have dominating winds from north-northeast and south-southwest, the pattern in summer is different.
A diurnal pattern is evident in the summer and spring with a sea breeze in the middle of the day coming from the northwest, something that you never see in winter. The diurnal effect is strongest from april to september. Lets look at two most extreme months to see the wind direction and strength by the hour.
