Summer has truly set in since the beginning of this week. I didn't even wear a coat this morning. Just three weeks ago I was still wearing my long, black wintercoat. (Weersverwachting: Zonnig en droog. Oost tot noordoost, toenemend matig, 3, langs de kust in de middag en avond af en toe vrij krachtig, 5. Minimumtemperatuur omstreeks 11 graden. Middagtemperatuur ongeveer 25 graden.) I don't mind a bit of sun, but why does it always get so extremely warm here? I feel myself getting irritated far sooner and also I am far more tired. I definately prefer winter. Most people don't agree however. Now, what exactly is Summer?
Summer, warmest season of the year, between spring and autumn. In the Northern Hemisphere, it is usually defined as the period between the summer solstice (year's longest day), June 21 or 22, and the autumnal equinox (day and night equal in length), September 22 or 23; and in the Southern Hemisphere, as the period between December 22 or 23 and March 20 or 21. The temperature contrast between summer and the other seasons exists only in middle and high latitudes; temperatures in the equatorial regions generally vary little from month to month. For physical causes of the seasons, see season.
The concept of summer in European languages is associated with growth and maturity, especially that of cultivated plants, and indeed summer is the season of greatest plant growth in regions with sufficient summer rainfall. Festivals and rites have been used in many cultures to celebrate summer in recognition of its importance in food production. A period of exceptionally hot weather, often with high humidity, during the summer is called a heat wave. Such an occurrence in the temperate regions of the Northern Hemisphere in the latter part of summer is sometimes called the dog days.
