Darkest December in Belgium since 1934
If you reached the end of the year feeling low in vitamin D, there's a good reason: last month was the gloomiest December in Belgium in more than 80 years.
The sun shone for a grand total of 10.5 hours last month - less than a quarter of the ordinary December average, which is 45 hours and eight minutes.
Statisticians at the Royal Meteorological Institute in Uccle had to look back as far as 1934 to find a darker December - when just nine hours 31 minutes of sunlight was recorded across the whole month.
December 2017 was also one of the wettest Decembers in recent memory, with 130mm of rainfall compared to a normal 81mm. It rained on 26 days in the month and there were nine days of storms, compared to the usual three.
Meanwhile, weather stats for the whole year show 2017 was one of the warmest on record (since 1833), on a par with 1989 and 2015. The average temperature at Uccle across the year was 11.3°C - and June and March were unusually hot.
