Weather Wednesday 7 October: mild before the rain
This Wednesday 7 October unfolds in two phases across Belgium. The afternoon offers one last spell of mild weather, with temperatures still reaching 23 to 25°C inland. Then rain arrives from the west in late afternoon and spreads across the entire country during the evening. By Thursday midday, we expect 10 to 30 mm, and notably cooler air will move in behind it.
- Morning: high clouds veiling the sun, fine clear spells especially in the south, 11 to 14°C
- Afternoon: still 23 to 25°C inland, 18 to 21°C in the west, first showers on the coast from around 16:00-17:00
- Evening: rain spreads across the country from west to east, reaching Liège and the High Fens around 20:00-21:00
- Totals: 10 to 30 mm by Thursday midday, heavier over the Ardennes and the High Fens; slight risk of thunderstorms
🌦️ Wednesday 7 October: mild afternoon, rain in the evening
🌙 Tonight: high altitude clouds, no rain
High altitude clouds are gradually spreading across the sky from the west, whilst the south and south-east keep a clear sky. The night remains dry and very mild in low-lying areas, with 10 to 13°C, but only 8°C in the far east of the country, and even a little less on the plateaus of the Eastern Cantons.
🌤️ Wednesday morning: hazy sun, clear spells in the south
Plenty of high clouds filtering the sun, without closing the sky: clear spells remain wide, especially in the south. It's already 11 to 14°C, and the air is becoming increasingly humid. The shift is approaching.
☀️ Wednesday afternoon: up to 25°C, before the first showers
The mildness is still remarkable for October: 23 to 25°C inland, with 24°C in Brussels, Liège and Mons, and 25°C in Namur. In the west, it's only 18 to 21°C: the first showers are reaching the coast and western Hainaut around 16:00 to 17:00.
🌧️ Wednesday evening: rain spreads across the country
Rain moves from west to east (approximate times):
- Coast and western Hainaut: around 16:00-17:00
- Mons, Charleroi and Namur: around 17:00-19:00
- Brussels, Ghent and the Famenne: around 19:00-20:00
- Antwerp, Limburg, Liège and the High Fens: around 20:00-21:00
It is moderate but persistent and continues through a good part of the night, especially in the east. Around 21:00, it is still 15 to 17°C. The south-westerly wind strengthens, with gusts of 50 to 65 km/h at the coast as the rain passes through. The risk of thunderstorms remains low: an isolated clap of thunder is not ruled out in the evening, particularly in the Ardennes and Gaume.
💧 How much rain by Thursday midday?
Between Wednesday afternoon and Thursday midday, we expect 10 to 30 mm in total. The lowest amounts concern the coast and the Antwerp region, around 10 mm. The centre will receive 10 to 20 mm, and the highest values, 20 to 30 mm, will affect theArdennes, Famenne, the High Fens and Limbourg.
