Forecasts for the next 42 hours
(BMCB Multimodel: ICOND2 – AROME-HD – ALADIN)
(These forecasts are usually updated daily)
Update 11 April 2026
A weak to moderate disturbance will cross the country over the next 42 hours, bringing generally modest precipitation totals, slightly higher south of the Sambre–Meuse line. Expected amounts range from 0.5–3 l/m² north of the Scheldt, 0.5–7 l/m² between the Scheldt and Sambre–Meuse, and 2–9 l/m² further south.
Today begins fairly bright with increasing high cloud. Rain will reach Flanders and western Hainaut by late morning. The afternoon turns mostly cloudy with rain, although clearer spells may develop over western Flanders. Highs will reach around 13°C along the coast, 16 to 20°C inland and 14 to 16°C over the higher Ardennes.
During the evening, rain will persist in many areas, while skies gradually clear over Flanders and western Hainaut. Overnight conditions become quieter with partly clear skies, high cloud and patches of fog, especially south of the Meuse. Lows will drop to around 5°C at the coast, 3 to 6°C inland and 1 to 4°C in southern areas, with local frost possible in sheltered valleys.
Tomorrow will remain largely dry. The morning will be fairly sunny but veiled by high cloud, particularly over central and southeastern areas. During the afternoon, more cumulus and high cloud develop, with somewhat brighter conditions near the coast and southern Ardennes. Highs will reach around 14°C at the coast, 12 to 16°C inland and 10 to 12°C over higher terrain.

National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update 10 April 2026
Following a cooler spell, a temporary rise in temperatures is expected on Saturday. The Belgian national thermal index should reach values between +3 and +4, allowing maximum temperatures to range from around 13°C along the coast to about 23°C inland.
This improvement will be short-lived. In the following days, and at least until 23 April, the thermal index is expected to fluctuate between 0 and +3, indicating a return to more moderate conditions.
In this context, daytime temperatures will generally range between 9 and 16°C on the least favourable days, while milder periods should see values between 13 and 20°C.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
Update 10 April 2026
A new rainy frontal system, preceded by a surge of very mild air, will cross our regions on Saturday. It will be followed by cooler maritime air from the Bay of Biscay, initially remaining relatively stable.
Conditions will turn more unsettled on Monday and Tuesday under the influence of a weak low-pressure trough (1008–1013 hPa) moving from England toward the North Sea and Denmark, bringing increased instability and some precipitation.
On Wednesday and Thursday, a milder southwesterly to southerly flow will reach our regions from southwestern France and northern Spain. Weak disturbances may still produce occasional rainfall, linked to systems affecting Brittany, the English Channel and England.
Trend from 17 to 24 April:
A weak northeasterly flow, relatively mild, is expected to establish over our regions as an anticyclonic ridge develops from northern Spain toward Scandinavia.
This high-pressure area should subsequently strengthen toward Iceland and Greenland, while a small depression moves from our regions toward the Baltic Sea. This evolution would bring renewed precipitation accompanied by cooler air from around 21–22 April.

Forecast of the range of temperatures, precipitations + general type of weather in Belgium
(These forecasts are usually updated daily)
Update 10 April 2026
Overview based on the BMCB multi-model (ICON – AIFS – GFS – ECMWF)
Following a relatively bright but cool and breezy sunday, the week will begin under mostly cloudy skies with some rainfall, initially more frequent south of the Sambre–Meuse axis before becoming more widespread on Monday.
On Tuesday, sunny intervals will return, although conditions remain somewhat unstable with scattered showers, mainly across the north and east. A new rain band will reach the western regions on Wednesday morning and extend eastward during the afternoon, while clearer spells gradually return from the west.
Thursday will remain changeable, turning mostly cloudy again with fairly widespread showers. Temperatures will be slightly cooler, with a moderate south to southwesterly wind and gusts of 30–50 km/h.
From Friday and through the following weekend, milder conditions are expected with often dry weather or only limited precipitation. Early next week should remain mild, but more active disturbances are likely between 21 and 24 April, bringing periods of rain or showers, at times moderate to locally heavy.

ALL Maps
Update 9 April 2026
Outlook from 27 April to 11 May 2026
Medium-range projections indicate the persistence of a broad high-pressure block extending from Greenland across central Europe toward the Caspian region. At the same time, low-pressure conditions are expected to remain over the central Atlantic and northern Russia.
Within this pattern, our regions would lie on the southwestern flank of the anticyclonic system, under the dominant influence of a continental easterly flow. This setup would favour the establishment of dry and very mild air, with generally stable weather.
Rainfall and thunderstorm activity would mainly affect southern Europe, particularly eastern Spain, much of the Canary Islands, the Maghreb and the eastern Mediterranean basin.
For the period from 4 to 11 May, high pressure would persist over Greenland and the northern Atlantic as well as over eastern Europe. Our regions would then experience a very mild to warm southeasterly flow.
Rain and thunderstorms would become more frequent over the southwest of the British Isles, western France and the Iberian Peninsula, as well as over Scandinavia, while persisting locally over the central and eastern Mediterranean.

Weather Outlook for 3-4 weeks
Weather Trend – Update 10 April 2026
Potential late-April warm spell followed by a more unsettled early May
Majority scenarios suggest that during the week of 27 April to 3 May, a warm and dry southerly flow may develop, leading to a renewed and marked rise in temperatures. Under this setup, near-summer conditions could temporarily establish across France and the Benelux, with locally high values possibly reaching or exceeding strong heat thresholds.
However, this evolution remains uncertain. Alternative model solutions favour a cooler and wetter scenario, which would limit the warming.
For the period from 4 to 10 May, covering early May holiday breaks, the trend points toward more disturbed conditions. The return of an unstable and moist Atlantic flow would bring more changeable weather. As temperatures would remain relatively mild, convective activity and thunderstorms could develop, particularly in a southwesterly flow.
This four-week outlook, updated every Thursday or Friday, remains subject to significant changes in upcoming revisions.

Weather Outlook for 3 months
Update – 25 March 2026
La Niña weakening, El Niño possible for summer
Ocean-atmosphere indicators in the tropical Pacific show that La Niña is gradually fading, with neutral conditions expected during spring. Multi-model projections suggest this pattern could favor the emergence of an El Niño event during summer.
This transition may lead to a more variable atmospheric circulation, influencing precipitation and temperature patterns across several regions, including Europe. As a result, the weather signal becomes more volatile and less predictable.
April: often influenced by anticyclonic conditions, turning relatively dry. Temperatures near to slightly above normal (+0.5 to +1°C). Risk of late frost early in the month. Below-normal rainfall.
May: stable and rather dry. Temperatures around +1°C above normal. Frequently pleasant conditions. Slight rainfall deficit.
June: potentially warm start to summer with frequent thunderstorm development. Temperatures +1 to +1.5°C above normal. Highly variable rainfall with strong regional contrasts.
