Lofoten is far north, at 68°N. The clothing you choose should be accordingly and is each participants responsibility. How you choose to dress up, will have a great significance both for your own safety and the enjoyment of the trip / course.
"Typical" Lofoten weather means that there can be two seasons in the same week! But the average temperature in July for the Lofoten is + 12.8°C and in January, it is around - 1°C. Sommer days with weather of + 30°C or + 4°C do not come every year, but they are not abnormal. In summer, it is just as important that you bring along sunscreen for the hot sunny days as well as warm clothing for the colder days. With the damp and raw air that we get here, it is important to have enough clothes on.
Lofoten is quite far to the north of 68 ° N. This means that clothing should be suitable for cold weather and each participant is responsible for all personal clothing on all trips and classes.
Since we are "right" in the path of the Gulf Stream, we get some mild winter days with temperatures above 5 ° C. This is the temperature at sea level. But at height and with a little wind, you can also get arctic conditions in Lofoten. During the coldest days, it can get down to around -18 ° C. Those days are rare, but must be taken into consideration when you pack your bag.
We are always using wool next to the skin, then a thin fleece or two and if you need more then that is OK too. The vital bit is to have a second set of wool in a drybag in case you get realy wet. I do always wear my woollen clothing dry on longer trips, it takes perfect conditions to dry wool outdoor during winter season.
Use the usual "mountain code" and dress up accordingly and then you can be fairly sure that you will get a good adventure - holiday in Lofoten.
