Rather cloudy but fairly bright in the morning, with sunny intervals. Cloudy from early afternoon, with slight rain now and again after 16.00 local time and into the evening, but not amounting to very much. Still a bit on the cool side. Moderate SW wind backed SSW in the evening.

Brussels Uccle 19.5°C – overnight minimum 12.3°C – 0.6 mm rain
Brussels Airport 20.1°C – overnight minimum 12.6°C – 1 mm rain
