Satellite image of Ireland, Northern Ireland, as well as Great Britain. It is not so easy to get a view of the region without cloud cover, but here we can clearly see the beautiful “40 shades of green” that the island’s countryside is famous for. The skies of Ireland tend to be covered by clouds most of the year, due to its geographical location close to Atlantic low pressure systems that bring humid, cloudy air flows across the area. The country’s sunniest months are May and June, where one may see between 5 and 6.5 hours of sunshine over most of the country each day. Photo courtesy of NOAA.
