National Thermal Indicator
(Chart)
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 31 January 2026 | 9 a.m.
Over the coming days, Belgium’s national thermal index will fluctuate between +1 and +4.
Minimum temperatures will range from 1 to 8°C during the mildest nights and from –2 to +4°C during the colder nights.
Maximum temperatures will reach 6 to 12°C on the mildest days and 2 to 8°C on the less mild days.
By the end of next week, a decline in the national index is still expected, though it should be less pronounced than forecast yesterday. This adjustment is due to the influence of parameters from the GEFS/GFS models (USA), which introduce additional variability into the thermal trends.
Between 5 and 14 February, the thermal index is expected to show marked fluctuations, with positive peaks between 0 and +2 on some days and negative values of –1 to –3 on others.
Expected temperature ranges
- Less cold days:
minimum temperatures between –2 and +5°C and maximum temperatures between 2 and 9°C. - Coldest days:
minimum temperatures between –4 and +2°C (locally lower in calm and clear conditions in valley bottoms south of the Sambre–Meuse line) and maximum temperatures between 0 and 6°C, depending on altitude.
This ongoing uncertainty within the BMCB multimodel is explained by Belgium’s proximity to a zone of air-mass conflict, with (very) cold air to the northeast of the country and (very) mild oceanic air extending across regions to the south.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps
UPDATE – 31 January 2026 | 11 am
Although our country lies close to a fresh to locally cold continental airflow affecting large parts of Germany and Central Europe, our regions will remain under the influence of mild to very mild air originating from the Alps and northern Italy until the middle of next week.
However, an intensification of low-pressure activity is expected towards the end of next week and during the following weekend, extending from the Bay of Biscay towards the Maghreb and the central Mediterranean. At the same time, high-pressure systems are forecast to persist over northern Europe and the Atlantic. As a result, the flow will gradually turn easterly to north-easterly, bringing increasingly cooler, and at times fairly cold, air. Weather conditions will become slightly unsettled, with the possibility of occasional light precipitation, falling as sleet or snow in some areas.
Likely evolution towards the end of the following week
With renewed Atlantic low-pressure systems moving towards the British Isles, the main flow is expected to slowly shift back to the south and south-west. Active Atlantic fronts would then affect our regions, bringing a marked rise in temperatures but also widespread rainfall. Temporary spells of snow or sleet will remain possible over the Ardennes high ground.

Overview of expected weather evolution – BMCB multimodel
Based on operational models and ensemble guidance from ICON, AIFS, GFS and ECMWF
Detailed forecast
📅 Monday 2 February
- Precipitation (24h): 2–11 l/m²
Mild and mostly cloudy. Showers during the morning, followed by bright spells in the afternoon.
Rain returns everywhere during the following night.
📅 Tuesday 3 February
- Precipitation (24h): 4–17 l/m²
Rather cool. Rain in the morning, especially in the northwest, then cloudy to changeable with showers.
Rain again overnight across the entire country.
Moderate easterly to south-easterly wind, gusts 35–55 km/h.
📅 Wednesday 4 February
- Precipitation (24h): 0–4 l/m²
Very mild. Cloudy start, then a sunny afternoon.
Some rain possible in the south overnight.
📅 Thursday 5 February
- Precipitation (24h): 0–3 l/m²
Cooler, generally bright and fairly sunny.
📅 Friday 6 February
- Precipitation (24h): 0 l/m²
Cool and often cloudy with a few brighter spells.
Some rain possible in the south overnight.
Likely trend
From Saturday 7 to Saturday 14 February, conditions remain cool and unsettled.
Frequent precipitation is expected, mainly rain at low levels.
In higher areas, sleet and snow become increasingly likely:
- Sleet from 200–400 m
- Snow from 500–600 m
By the weekend, locally heavier precipitation cannot be ruled out.

Outlook anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Update – 30/01/26:
During the second half of February and into early March, low-pressure systems would increasingly retreat towards the Atlantic. At the same time, a milder southerly to south-westerly flow, occasionally unsettled, is expected to spread across our regions.
Thereafter, a scenario is being considered in which a low-pressure system becomes established over southern Scandinavia and northern Germany between 9 and 16 March, a pattern conducive to showery and unstable conditions.

Weather Outlook for 3-4 weeks
Update 30-1-26
Period from 14 to 22 February: unsettled, but temporarily rather cold
Depression activity is likely to remain dominant. Several frontal systems may continue to affect our weather, with temperatures initially close to or slightly below seasonal averages. Towards the end of the period, a modest temperature recovery cannot be ruled out.
Week from 23 February to 1 March: a return to calmer conditions
A shift towards a southerly flow appears likely, while low-pressure systems track further north towards the British Isles. As a result, frontal systems would mainly affect northern Europe, allowing high pressure to build in more effectively. Weather conditions should become calmer and drier, with milder temperatures, generally 2 to 3°C above the seasonal norm.
***************
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.
