National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 7 March 2026
Over the coming days, the national thermal indicator is expected to gradually return to values between +6 and +3.
Under these conditions, daytime temperatures may still reach 13 to 20°C on the mildest days, although they will most often range between 10 and 17°C.
From 14 March onward, the trend would indicate a renewed decline in the national indicator, which could fall between +3 and –1.
Maximum temperatures would then range between 8 and 15°C on the milder days, while cooler periods would limit highs to around 7 to 13°C.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
UPDATE – 7 March 2026
Very mild continental air masses will continue to move across the country in the coming days. Initially arriving from Central Europe, they will later be increasingly fed by air flowing from the Alps and the Mediterranean Basin.
At the beginning of next week, this very mild air mass will gradually become more unstable. A few showers are expected to develop first over the western parts of the country before spreading elsewhere as the airflow turns to the south and south-west.
This flow originating from the Bay of Biscay is likely to strengthen somewhat during the second half of the week. However, it will precede the arrival of a rainy cold front that should cross the country between Friday and Saturday.
Behind this front, the following weekend and the start of next week should see the return of cooler air, still accompanied by a risk of precipitation.

Update – 7 March 2026
Weather outlook based on the BMCB multimodel
(Operational models and ensembles ICON – AIFS – GFS – ECMWF)
Weather conditions will remain very mild for the season during the first part of next week. Morning fog patches are likely on several days, particularly over the lowlands and south of the Sambre-Meuse corridor. There will be periods of sunshine, but the risk of showers will gradually increase, especially from mid-week and during the weekend.
Monday 9 March
Morning fog patches, mainly over the plains. Afterwards fairly sunny and very mild. Late in the day the risk of local rain or showers will increase over western Belgium. Overnight fog formation is again likely, especially south of the Sambre-Meuse axis.
Precipitation: 0–5 L/m²
Tuesday 10 March
Very mild with local morning fog. Initially fairly sunny, later a growing chance of local showers. Fog may reform overnight, particularly over the southeast of the country.
Precipitation: 0–7 L/m²
Wednesday 11 March
Still very mild. Local morning fog, mainly south of the Sambre-Meuse corridor. Some sunshine at first, followed by an increasing risk of showers. Breezy with gusts of 35–55 km/h from the south to southwest.
Precipitation: 0–9 L/m²
Thursday 12 March
Very mild and mainly dry, with variable cloud and good sunny intervals.
Precipitation: 0 L/m²
Friday 13 March
Some sunny spells at first, then becoming cloudier with rain moving in from the west. Windy with gusts of 45–65 km/h from the south to southwest.
Precipitation: 0–10 L/m²
Trend
Between 14 and 21 March, conditions remain mild but unsettled, with periods of rain or showers, occasionally moderate. Around 17 March, the air mass may become somewhat cooler.

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.
