(These forecasts are usually updated daily)
Update 9 April 2026
Precipitation totals over the next 42 hours will remain very limited, with virtually none north of the Scheldt and only 0 to 3 L/m² elsewhere. Today begins sunny with high-level cloud veils. Temperatures will rise to around 19°C along the coast and 23 to 25°C inland, with 21 to 22°C over the higher Ardennes.
Cloud cover will increase from the west late in the afternoon and during the evening, bringing a risk of a few light showers and possibly an isolated thunderstorm, especially over the Campine region. Overnight, skies become mostly cloudy to overcast with local light rain, mainly across the Ardennes. Winds turn northwesterly and strengthen. Minimum temperatures range between 3 and 9°C south of the Sambre–Meuse axis, 7 to 9°C inland and around 8°C at the coast.
Tomorrow will be noticeably cooler, with often cloudy skies in the morning and some temporary bright spells, particularly across Wallonia. During the afternoon, conditions turn variable with sunny intervals and cumulus clouds, although high cloud persists. Highs will reach about 9°C at the coast, 13 to 14°C inland and 8 to 12°C over the higher Ardennes. The evening remains rather cloudy with high-level cloud and a cool feel.

Update 9 April 2026
Only minor changes compared to yesterday’s outlook. The mild peak expected on 9 April will mark the most significant phase of the period, with the national thermal index reaching +6 to +7 and daytime highs ranging between 19 and 25°C across Belgium. 🌤️
This spring-like spell will be short-lived. In the coming days, the thermal index will drop quickly and then fluctuate between -1 and +3, a trend expected to persist at least until 23 April.
Within this more moderate regime, maximum temperatures will most often range between 14 and 21°C on the mildest days. During cooler intervals, they will generally be limited to 7 to 14°C, reflecting a return to more seasonable values. 🌦️

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
Update 9 April 2026
Following the west-to-east passage of a weak cold front overnight, a 1020 hPa high-pressure cell will build on Friday within the cooler air spreading across the Benelux. This will bring a brief improvement before conditions deteriorate again.
On Saturday, a more active disturbance linked to a deep low-pressure system around 968 hPa, centred northwest of Ireland, will cross our regions. The low will then move northward, maintaining an unstable southwesterly oceanic flow.
Early next week, another low of about 1008 hPa will reach the English Channel and northern France on Monday, before shifting toward the Gulf of Genoa on Tuesday. In its wake, a cooler northerly to northeasterly flow will develop, but a ridge extending across the North Sea, England and western France will promote more stable conditions.
This ridge is expected to persist for several days, bringing dry, calm and fairly mild weather for the season.
Outlook for 17–23 April:
High pressure is likely to persist from Scandinavia to the Bay of Biscay, ensuring generally calm, dry and even milder conditions. Afterwards, a return to northeasterly to northerly flow is possible, with still pleasant temperatures inland but a gradually increasing risk of rainfall.

Update 8 April 2026
Trend based on the BMCB multi-model (ICON, AIFS, GFS, ECMWF)
After a contrasting late-week period, including a more active disturbance on Saturday, conditions will remain changeable into early next week. Friday will be cooler but dry, with a mix of cloud and sunny intervals. On Saturday, a disturbance arriving from the west will bring sometimes significant rainfall in still relatively mild and windy conditions, with southeast gusts of 30–50 km/h.
On Sunday, cooler air spreads across the country with mostly cloudy skies and lingering rain in the east. Early next week remains unsettled, with cloud and showers, more frequent on Tuesday.
From midweek onward, a gradual improvement is expected. Precipitation will become lighter and more sporadic, while conditions turn drier. Between 16 and 22 April, generally mild weather should dominate, with little or no rainfall and increasing anticyclonic influence

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 of 2 April 2026
Onset of a spring-like pattern toward the end of April
According to the latest projections, the period from 20 to 26 April could mark the return of more spring-like conditions across our regions. Temperatures are expected to be close to seasonal averages, with an overall pleasant feel. Sunshine and cloud intervals should alternate within a prevailing southwesterly flow, favourable for the development of the first localized convective instability.
For the week from 27 April to 3 May, this tendency toward rather pleasant weather could be confirmed. Temperatures would remain near to slightly above normal, with an anomaly of around 0 to +1°C. Early May would therefore be fairly mild, though occasionally unstable, with a risk of thundery showers. The precipitation outlook remains more uncertain at this stage.

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.
