National Thermal Indicator
(Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 1 January 2026 | 10 AM
According to the latest projections, the national thermal index is expected to remain in negative territory at least until 12 January, signalling a firmly established winter pattern.
Over the coming days, the index is likely to fluctuate mostly between –2 and –5, reflecting persistently cold daytime conditions. During the milder phases, daytime highs would struggle to rise above –3 to +4°C, while during the coldest periods they may barely reach –5 to +2°C.
Minimum temperatures will show considerable variability across the country, generally ranging between –7 and +3°C. However, during calm and clear nights, radiative cooling may become more pronounced. In valleys south of the Sambre–Meuse line, temperatures could locally drop to between –7 and –13°C, significantly intensifying the wintry cold.
A slight moderation is suggested by the BMCB multimodel ensemble after 12 January, though without a marked thaw. The thermal index would remain between 0 and –2, corresponding to daytime highs of 0 to +7°C and overnight lows generally ranging from –3 to +4°C across Belgium.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps (6=>? days)
Update – 31 December 2025 | 11 AM
On Friday, a deep low-pressure system of 974 hPa, centred over the Baltic Sea, will steer a cold and unstable polar airflow towards the North Sea and our regions. Under this influence, conditions will remain unsettled, with frequent showers, particularly affecting the north-eastern half of the country.
This cool air mass will continue to dominate throughout the weekend, as low-pressure systems track between the North Sea and Scandinavia. As a result, the weather will remain changeable and unstable.
However, a gradual shift in the weather pattern is expected at the beginning of next week. The advance of an upper-level ridge of high pressure towards our regions should dampen low-pressure activity and progressively reduce instability, paving the way for calmer conditions.

Weather Update –31 December 2025 | 1 PM
Summary of the expected weather evolution
based on the BMCB multimodel (operational models and ICON – AIFS – ECMWF ensembles)
As the new year begins, Belgium is heading into a prolonged winter spell, characterised by cold temperatures, recurrent instability, and frequent wintry precipitation, varying in form depending on region and timing.
📅 Friday, 2 January
A rather cold day with a highly changeable sky.
After bright spells in the morning, conditions will deteriorate gradually from the west. Rain will spread across the country and turn into sleet or snow, certainly in the Ardennes and locally across lowland areas during the night.
Winds will be brisk, with gusts of 50–70 km/h from the southwest, shifting to northwesterly along the coast, before easing later.
- Precipitation: 0.5–15 L/m²
- Minimum temperatures: –3 to +3°C
- Maximum temperatures: –1 to +5°C
📅 Saturday, 3 January
The cold conditions persist.
A very changeable sky will bring sunny intervals, but also snow showers across the north-eastern half of the country (Antwerp, Limburg, Liège). During the following night, snow showers will become more widespread.
Winds remain noticeable, with gusts of 35–55 km/h from west to northwest.
- Precipitation: 0–15 L/m²
- Minimum temperatures: –5 to +1°C
- Maximum temperatures: –3 to +3°C
📅 Sunday, 4 January
A continuing wintry atmosphere, with a highly variable sky.
Snow showers will again affect mainly the north-east, interspersed with occasional brighter spells.
- Precipitation: 0–10 L/m²
- Minimum temperatures: –5 to +1°C
- Maximum temperatures: –3 to +3°C
📅 Monday, 5 January
Still rather cold, but calmer.
A variable sky with lengthy bright spells and mostly dry weather.
- Precipitation: 0–5 L/m²
- Minimum temperatures: –6 to 0°C
- Maximum temperatures: –3 to +3°C
📅 Tuesday, 6 January
The cold intensifies slightly.
Conditions turn variable to cloudy, with locally rain, but also snow or sleet, mainly above 200 metres.
Southerly winds will strengthen at times.
- Precipitation: 0–5 L/m²
- Minimum temperatures: –7 to –1°C
- Maximum temperatures: –3 to +3°C
🔎 Likely trend
From 7 to 14 January, the weather remains predominantly cold to cool, with recurrent wintry precipitation, especially snow in the Ardennes, before a gradual shift toward wetter and slightly milder conditions later in the period.

Forecast anomalies at 500 hPa

( charts )
Weather Update – 31 December 2025 | 8 AM
The latest ensemble forecasts show strong agreement for the period from 5 to 12 January. They point to the establishment of a broad low-pressure system stretching from the western Maghreb across Central Europe to the Baltic states.
Within this pattern, our regions would remain under the influence of a predominantly north-westerly to westerly flow, at times turning more north-westerly to northerly, favouring cooler and often unsettled conditions.
During the second and third ten-day periods of January, however, a shift in the large-scale circulation appears increasingly likely. The main flow would gradually veer towards the south to south-west, while low-pressure activity becomes increasingly concentrated over the Atlantic, close to the British Isles. This would allow milder maritime air to spread across the region, accompanied by more frequent disturbances and rainfall.
According to current indications, this atmospheric configuration could persist until the end of January and extend into the opening days of February, suggesting a continuation of generally mild yet often unsettled winter weather.

Weather Outlook for 3-4 weeks
Update 31-12-25
Weather Trends – Mid to Late January
15 to 25 January: mild and unsettled conditions
This period is expected to be influenced by a west to south-westerly airflow, remaining fairly unsettled. Between 19 and 25 January, a succession of Atlantic low-pressure systems could affect the region, bringing recurrent spells of rain, interspersed with temporary quieter intervals.
Within this pattern, temperatures are likely to rise slightly above seasonal averages, though without any pronounced anomalies. Overall, this would result in a generally mild and humid winter regime, driven by Atlantic influences.
26 January to 1 February: potentially calmer and more seasonal
At this range, forecast confidence remains low, and these trends should therefore be interpreted with caution.
Based on the current ensemble mean of the models, a gradual easing of conditions cannot be ruled out. Weather patterns could then move closer to seasonal norms, with temperatures near average and a changeable sky, but without any significant disturbances.
Such a configuration would be conducive to the formation of fog and low cloud, particularly across low-lying areas and valleys, due to stable conditions in the lower atmospheric layers.
***************
Weather Outlook for 3 months
Update 13-12-25 – 3:00 PM
January 2026: a wintry spell before milder conditions return
January 2026 is expected to open with a distinctly wintry phase, followed by a clear and lasting return to milder conditions during the second half of the month.
The nationwide temperature anomaly is estimated at +0.7°C, pointing to an overall mild month despite a cold start.
Early January could bring low temperatures and a risk of snowfall reaching lowland areas.
From mid-January onwards, Atlantic influences are likely to dominate, bringing temperatures well above seasonal averages.
In terms of precipitation, a slight surplus (+5%) is anticipated. Weather systems would be fairly frequent at the beginning of the month under a northerly flow, before shifting to a westerly to south-westerly Atlantic regime from mid-month.
As a result, January could become the wettest month of the 2025-2026 winter.
February 2026: slightly drier and still mild
February is expected to remain generally mild, with a temperature surplus close to +1°C.
Weather conditions are likely to be contrasting, with cold mornings followed by milder and often sunny afternoons, as high-pressure systems settle more frequently over the region.
Precipitation totals would be slightly below average (-10%), with less active weather systems due to the influence of persistent high pressure over continental Europe.
March 2026: finally a seasonal month?
March could finally deliver near-average seasonal conditions.
Temperatures are expected to fluctuate around climatological norms, with alternating cooler periods and milder, more unsettled phases, typical of early spring.
Precipitation should be close to average overall, though locally below normal, under the possible influence of high-pressure systems over northern Europe.
