The daily weather log
For most of June and July, temperatures were warmer than normal, especially at night. There were a couple of severe frosts in late June, and one in mid-July. The coldest part of winter, however, came extremely late. In the second week of August, both days and nights were six degrees colder than normal. There were more sub-zero nights in August than in June and July together.
Early morning dew points above 7° in early June showed high humidity. Later, dew points below zero showed the air was extremely dry in late June and almost all of August.
The winter was a little less frosty than usual, with 40 frosts rather than the usual 44. There were 24 readings below zero and 7 below minus two, but none below minus four.
There were 21 rain days, totaling 136 mm. Most rain came early in the season. The first rain day, with 38.2 mm, was the wettest winter day in ten years.
July and August were extremely cloudy months, with 52% and 55% cloudy mornings. June, at 37%, was also cloudy.
Comparing winter seasons
Mean daily temperatures (daily maximum, minimum, and mean) were close to normal this winter. Because the maximum was slightly down, and the minimum slightly up, the daily temperature range was reduced. At 14.1°, it was narrower than the normal 15.3° but not extreme like the 13.2° of last winter.
The mean dew point of 1.9° was normal for winter.
The rainfall total of 134 mm is above the long-term average for winter (125 mm). The graph includes the ninth driest winter, 2002. Just ten years ago, 304 mm of rain in the winter of 1998 made it the second wettest on record.
This was the cloudiest winter of the decade. Forty-eight percent of the mornings had more than 4/8 cloud. The winter average is thirty-one percent. The graph suggests a trend to more cloudy winters since 2002.
