Average temperatures in 2018 match all-time record

The average temperature at the Ukkel Weather Centre (Brussels) in 2018 was 11.9°C, equalling the record set in 2014. Writing on Twitter, the VRT’s weatherman Frank Deboosere described 2018 as “Extremely warm, very sunny and very dry”.  

2018 was certainly an exceptional year. There were just 142 days on which rainfall was recorded at the Ukkel Weather Centre. This is the lowest number since records began in 1833. In an average year rain falls on 200 days.

The total amount of precipitation was exceptionally low at just 650.2 mm. This is 200 mm less than in an average year. Nevertheless, there have been years in which there was less precipitation. For example in 1989 there was 639.5mm and in 1921 there was just 406.4mm.    

2018 was exceptionally sunny with 1,898 hours of sunshine having been recorded during last year. This is 350 hours more than in an average year. In recent years only 2003 was sunnier.

The summer of 2018 was the warmest since records began. At 132, the number of days on which temperatures reached 20 degrees or more was the highest ever. Only 1947 (with 66) had more days on which temperatures reached 25 degrees. Last year this was the case on 61 days.  

The highest temperatures last year were recorded on 27 July in Hechtel-Eksel (Limburg), when temperatures reached 38.8 degrees. The year’s lowest temperature (-18.2°C) was recorded at Neidingen, near Sankt Vith (Liège province) on 28 February.
