Update – 9 March 2026
Precipitation expected over the next 36 hours
Rainfall totals will remain generally modest, although regional contrasts are expected:
- North of the Scheldt: 0.5 to 3 L/m²
- Between the Scheldt and the Sambre–Meuse valley: 0.5 to 5 L/m²
- South of the Sambre–Meuse valley: 1 to 8 L/m²
Weather situation today
This morning
Widespread fog and persistent low stratus mainly affect the province of Antwerp and the two Flanders. Elsewhere the weather is already sunny or becoming largely sunny.
- Wind: variable or southerly, 5 to 10 km/h.
This afternoon
Low clouds and fog may still linger near the coast. Across the rest of the country the weather will be bright with plenty of sunshine, with cumulus development possibly producing very isolated showers, mainly south of the Sambre–Meuse valley.
- Wind: south-westerly, 5 to 25 km/h, but north-easterly along the coast.
- Maximum temperatures: around 13°C at the coast, 17 to 20°C inland, 15 to 17°C in the Ardennes.
In the evening
Fog will redevelop, especially over West Flanders and locally in inland valleys. Elsewhere skies will gradually clear, although a few last showers may still occur, particularly in the provinces of Liège and Limburg.
- Wind: variable, 0 to 15 km/h, north-easterly at the coast.
Tonight
Extensive fog or low stratus is expected in West Flanders and the Campine region, while patchy fog may form in some inland valleys. Elsewhere the sky will remain cloudy to variable, with a slight risk of showers from the west towards the centre of the country.
- Wind: variable to southerly, 0 to 15 km/h.
- Minimum temperatures: around 6°C at the coast, 7 to 11°C inland, 0 to 5°C south of the Sambre–Meuse valley.
Forecast for tomorrow
Morning
Fog will dissipate quickly. Skies will then remain often very cloudy, with rain or showers, except in West Flanders, where conditions should remain generally drier.
- Wind: variable to south-westerly, 5 to 25 km/h.
Afternoon
A few brief clear spells may develop, but skies will remain mostly cloudy with rain or showers across most regions, except over the two Flanders.
A very isolated thunderclap cannot be ruled out in showers, particularly east of the Meuse.
- Wind: south-westerly, 25 to 40 km/h.
- Maximum temperatures: around 12°C at the coast, 14 to 15°C inland, 10 to 13°C in the Ardennes.
In the evening
Clearer intervals will spread from the west, although skies will remain rather cloudy, with the last showers possible in the Campine region and south of the Sambre–Meuse valley.

National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 9 March 2026
The national thermal indicator is expected to gradually decline over the coming days, reaching values between +4 and +1 by 12 March.
This would correspond to maximum temperatures ranging between 8 and 15 °C across the country.
Afterwards, the indicator should stabilise around neutral levels, fluctuating between +1 and −1. This would result in daytime temperatures close to seasonal averages, with 4 to 11 °C on cooler days and 7 to 14 °C during milder periods.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
UPDATE – 9 March 2026
From Tuesday onwards, the airflow will turn south-westerly, bringing less mild and more unstable maritime air to our regions, with scattered showers.
On Wednesday, a fairly active cold front will cross the Benelux from west to east. It will be followed on Thursday by a temporary lull in a rather fast Atlantic flow. Within this current, another rain-bearing disturbance will move across the country on Friday.
Over the weekend and into the beginning of next week, this system will be followed by a relatively cool and unstable air mass, producing frequent showers.
Thereafter, shower activity should gradually decrease under the influence of a strengthening high-pressure cell moving from France (around 1020 hPa) toward the North Sea (near 1032 hPa).
By the middle of next week, this evolution is expected to place our regions in an increasingly north-easterly flow, with temperatures returning closer to seasonal averages.

Trend of 500 hPa anomalies (around 5500m) across Europe and the Atlantic Ocean
ALL Maps
Update – 7 March 2026
Outlook for late March
Projections at the mid-tropospheric level indicate the development of a broad anticyclonic area extending from northern Scandinavia towards the Atlantic Ocean, while a low-pressure system would remain established over the Mediterranean Basin.
In this pattern, our regions would experience a continental airflow bringing relatively mild and fairly dry air, favouring generally stable conditions with limited precipitation.
Early April
At the beginning of April, the anticyclonic area is expected to shift further west towards Iceland, while the Mediterranean low would remain centred near Tunisia.
Such a configuration would generate a northerly to north-easterly flow over our regions. The air mass would remain rather dry, although temperatures would tend to return to values closer to the seasonal average.

Weather Outlook for 3-4 weeks
Update – 6 March 2026
Week of 23–29 March: dry weather and possibly cooler conditions
The currently favoured scenario in the models maintains a dominant high-pressure system over northern Europe. Under such a pattern, disturbances would remain scarce across our regions and the general atmospheric flow would stay rather weak.
This setup would favour mostly dry conditions. It could also lead to marked daily temperature ranges, with rather cool mornings under often clear skies followed by mild and distinctly spring-like afternoons.
Week of 30 March to 5 April: a last potentially damaging frost for crops?
During this transitional week between late March and early April — approaching the Easter period — weather conditions should remain generally calm and rather dry.
However, an intrusion of cooler air from the north cannot be ruled out. In such a scenario, attention will need to be paid to the risk of spring frost. Following a very mild end to winter and advanced vegetation growth, a return of frost could locally cause significant damage to crops.
At this stage, the reliability of this outlook remains limited and will require confirmation in the coming days.
***************
Weather Outlook for 3 months
Update 11-2-26
March: slightly drier, more often under high pressure influence
Temperatures:
The most likely scenario points to values near or slightly above the seasonal average. The projected anomaly is around +0.7°C, with fairly good confidence. Short-lived cooler spells remain possible.
Precipitation:
No clear nationwide signal. Alternating unsettled and quieter phases may produce marked regional contrasts. The expected anomaly is around -5%, but with low confidence.
General pattern:
The circulation remains fairly mobile, with a low-pressure axis still extending from the Atlantic towards Spain, gradually weakening. This may evolve into a typical late-winter/early-spring regime, with rapid shifts between mild westerly/southwesterly flows and cooler incursions.
April: broadly seasonal
Temperatures:
Close to average or slightly above, depending on the region. The anomaly is estimated at +0.6°C, with fairly good confidence — a moderate deviation close to normal. Cold, occasionally frosty nights remain possible during calm high-pressure periods.
Precipitation:
A slightly drier tendency during anticyclonic phases (-7%), though confidence is limited.
General pattern:
The Benelux is often positioned between low-pressure systems over southern Europe and the Mediterranean and more persistent high pressure over eastern Europe.
May: variable, without significant anomaly
Temperatures:
Near-average values, around +0.5°C (not statistically significant). Under clear skies and northerly high-pressure flow, cool or locally frosty nights remain possible, despite generally mild daytime conditions. Confidence is limited.
Precipitation:
A slightly drier signal (around -10%), but with very large scenario spread. Typical spring showers, sometimes thundery, cannot be ruled out.
General pattern:
The Atlantic high may at times promote northerly flows, favouring cooler nights and reduced precipitation.
