In 1921, there were 153 such days in Belgium, meteorologist David Dehenauw said on Twitter on Friday.
On the other hand, 2018 was not one of the driest years. Dehenauw said he expected about 645 millilitres of rain in Uccle, about 200 mm less than normal, but not low enough to earn 2018 a slot among the top 10 driest years.
Average temperature now stands at 11.8°, making 2018 the second hottest year since 2014, which registered an average of 11.9°.
Uccle recorded 1,900 hours of sunshine this year, the sixth highest annual total since 1887.
