the year is, of course, greatest in Finmarken, averaging from 243 at
Kautokeino to 205 at Vardø and Alten, and 188 at Gjesvær. In
Hatfjelddalen, there is an average of more than 200 days of frost
in the year, and at that station, as well as at Karasjok and
Kautokeino, night frosts are observed in all the months of the year.
The smallest number of frosty days — 100 and less — is found
in Lofoten, and at the outermost lighthouse stations southwards
along the coast. The temperature remains low far on into the
spring, especially in Finmarken; not until the end of April or the
beginning of May, does the diurnal mean temperature rise above
32°, and June has a mean temperature that is no higher than
that of May farther south. Summer, however, often comes pretty
suddenly in these parts, when the sun’s rays, unimpeded by clouds,
can exert their influence both day and night.
Wind. The average velocity of the wind, which reaches
22 miles an hour at the outermost coast stations in Finmarken and
Lofoten, is also considerable elsewhere; only at the inland stations,
where there are often calms and seldom storms, it is from 4 to 9
miles an hour. The coast stations of Finmarken have the greatest
number of stormy days in the year, viz. 45 to 62. Trondhjem
has 44, elsewhere on the coast, 20 to 30 is the most usual number.
Far up the fjords and upon the Finmarken plateau, the number of
stormy days does not amount to 5 in the year. Most of the
storms all through the year come from the SW and W. At Vardø,
however, during the summer, they are generally from the NW.
The storms are most frequent in the winter, from November to
March. The prevailing winds are westerly to northerly in the
summer, southerly to easterly in the winter.
Rainfall. The maximal zone for annual rainfall, which as
stated above, passes within the coast-line in western Norway,
following its direction, continues also northwards, though not with
such high absolute rainfalls. We find, for instance, a maximum
of 51 inches north of the Trondhjem Fjord at Berge, and 47
inches within Rødø, as also an especially marked maximum of more
than 59 inches at Svolvær in Lofoten. Otherwise, the rainfall
diminishes eastwards inland towards the Swedish frontier, at several
places, to as little as 20 or 16 inches. There is also a smaller
rainfall on the southern and western Lofoten Isles. Thus Røst
has only 28 inches annual rainfall. From Svolvær’s maximum,
the rainfall diminishes slowly northwards along the coast to
