There is rain, wind and cold, rarely sunshine. The temperature hovers around 7 degrees. This is not really a place for sun or winter sports. Bring waterproof clothing.
JasperThere were sunny days, but they were rare. The scenery is breathtaking, but the weather conditions were not ideal.
MachteldWe had sunny days, but also the typical Irish clouds and rain. The air temperature was between 10 and 18 degrees. Beautiful green scenery, but don't forget your umbrella.
NinaCold, cloudy, rainy and very little sun. This is more for adventurers than sunbathers.
LucasAlthough it was changeable, the unpredictability added to the charm of the landscape.
FelineThe temperature was pleasant, about 15 degrees. Beautiful green landscapes thanks to the frequent rainfall. It is not exactly a place for sunbathing or winter sports, but it is beautiful in its own way.
LennartWe had both sunny and rainy days. Although it was not cold, it was not warm enough for swimming. Beautiful green landscape thanks to the rain.
