WEATHER IN SWEDEN October, 1923-Feb. 1, 1924 October in Stockholm could scarcely be distinguished from August. The sensible temperature was about the same; in fact I needed a winter overcoat once about the 1st of August, which I never did in October. It was unusually warm for the month, and the even temperature maintained by the numerous bodies of water which completely permeate Greater Stockholm, so that it is a veritable Venice, made this month very pleasant. There was an absence of the cold, chilling winds which charac terize the football weather of northeastern America at this season. There were no strong instrusive highs. Atmospheric conditions were quite stable, and advantage was taken of this for advertising with "smoke-writing" by airplane. In northern Sweden above lat. 63° many birches had turned yellow by September 20th, but in Stockholm leaves were green throughout October. The saying: "It never rains but it pours" does not apply to Sweden, for here it rains as long as possible and uses the least possible amount of water in doing so. It is interesting to note by way of digression, that whereas Swedes and Norwegians first settled in Minnesota, Michigan, North Dakota, etc., in late years they have been going more and more to Oregon, Washington, and British Columbia, where the climate is more similar to their home land. I wonder who among them first discovered that fact? November was much the same as October; at least the transition from apparent summer to winter was so gradual that one scarcely noted it, nor missed the fall. After the middle of the month the weather was often distinctly cool without overt acts of freezing, and after the 20th snow enough accumulated for ski-running and sleighing in the country. The accumulation of snow was not so much due to winter weather at first, but to the inability of the weak sun to melt the nights' frost, and what little snow that fell from time to time, and to the absence of heavy rains. The first part of December continued these conditions, and the last half brought severe cold and clear weather. Even to one accustomed to the perversities of New England weather, the sullenness of the Swedish drizzle is depressing, due probably in large part to the shortness of days at this season. The stimulus of sharp changes, which, according to some, is stimulating to mental activity especially, is lacking here. On the other hand, houses are not overheated, and the absence of sudden temperature changes makes it easier for one to avoid chilling and taking cold. From my diary I note the following general sky conditions during October, November and December, in Stockholm: |
