Today: sunny start, cloudier later on
This Sunday morning begins with widespread sunshine over the Campine region, western parts of Liège province, Namur, eastern Brabant, and northern Belgian Luxembourg. Elsewhere, cloud cover is more extensive and locally dense.
The wind blows from the south-east, with gusts ranging from 10 to 30 km/h.
During the afternoon, cloud cover gradually increases, although some sunny intervals remain possible. Conditions turn notably cloudier over southern Belgian Luxembourg and western Flanders.
Maximum temperatures reach around 7°C along the coast, range between 1 and 9°C inland, and remain close to 0°C in the High Ardennes.
Evening and night
In the evening, fog patches gradually develop across the Ardennes, locally extending into lowland areas. Elsewhere, skies remain cloudy with occasional clear spells.
The night is expected to be rather misty, with widespread fog banks and a cloudy to overcast sky, slightly clearer across the western half of the country.
Minimum temperatures fall to around 3°C at the coast, -1 to +3°C inland, and -3 to +1°C south of the Sambre–Meuse axis.
Tomorrow
On Monday morning, fog may persist locally, in some places until late morning. Skies remain cloudy to overcast, though bright intervals will develop over Flanders and Hainaut.
Winds will be light and variable, becoming moderate westerly over the Ardennes high ground.
In the afternoon, cloud cover remains dominant with occasional breaks. Maximum temperatures will reach about 4°C along the coast, 5 to 7°C inland, and 0 to 4°C in the High Ardennes, confirming a cold but stable weather pattern.

National Thermal Indicator

(These forecasts are generally updated daily)
Update – 24 January 2026 | 9 a.m.
Belgium’s national thermal index is currently trending downward and is expected to reach its lowest point on Monday 26 January, with values between –2 and –3. This will result in a temporarily colder spell, with daytime maximum temperatures ranging from 0 to 7 °C, depending on the region. Minimum temperatures will fluctuate between –3 and +3 °C, with the lowest values occurring in rural areas and at higher elevations.
This cold snap will, however, be short-lived. From Thursday onwards, the thermal index is forecast to rise gradually, reaching values between +2 and +5 by the end of January. Daytime temperatures will then climb to 5–11 °C, more in line with a typical maritime winter pattern. Night-time minima will initially range between –1 and +5 °C, before becoming milder, reaching 3 to 9 °C across many areas.
In early February, current trends suggest a renewed decline in the thermal index, towards values between 0 and –2. This would imply a return to colder conditions, with maximum temperatures of 0–4 °C in the Ardennes and 4–8 °C across the lowlands. Minimum temperatures could then fall to –4 to –1 °C in the Ardennes, and range between –1 and +4 °C in the lowlands and along the coast.
These developments still require confirmation, but they illustrate a period from late January into early February marked by rapid alternations between winter chill and relative mildness, a pattern typical of the season.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps
Update – 24 January 2026 | 11:00
A marked evolution of the atmospheric pattern is expected over the coming days. On Sunday, a broad low-pressure system, with central pressure ranging between 996 and 988 hPa, will extend from Ireland to northern Italy via western France. This setup will place our regions under the influence of a progressively cooler but relatively stable easterly flow. Within this context, the development of an anticyclonic ridge is expected on Monday, bringing a temporary spell of calmer conditions.
On Tuesday, a more pronounced change is forecast with the arrival of a very deep depression, with a central pressure near 962 hPa, between Ireland and Brittany. Its associated frontal systems will gradually spread across England, France and subsequently the Benelux, bringing more widespread precipitation.
On Wednesday, these disturbances will be followed by a relative mild spell, driven by a weakly unstable south-westerly flow originating from south-western France and the Bay of Biscay.
This transition will be short-lived. On Thursday, another deep low-pressure system, estimated at 965 hPa, is expected near the mouth of the English Channel. The associated rain bands will also cross our regions during the night from Thursday into Friday.
The following weekend is expected to remain very mild, but often unsettled or unstable, with alternating wet periods and brief breaks.
Outlook for early February
On a synoptic scale, low-pressure systems are likely to dominate the central Atlantic, extending towards France, southern parts of the British Isles, the Benelux, the Alps and Italy. This pattern would keep our regions under frequently unsettled and unstable maritime air.
After 5 February, a shift in the overall pattern is suggested. The main zone of depression activity may move slightly further south, stretching from the Atlantic towards France and northern parts of the Balkans. This would allow colder air over northern Europe to advance towards the British Isles, the North Sea, the Netherlands and northern Germany, opening the door to cooler conditions in these areas.

Update – 25 January 2026 | 13:00
Analysis based on the BMCB multi-model (operational models and ensembles ICON – AIFS – ECMWF)
The end of January is expected to be meteorologically very dynamic, with a succession of Atlantic disturbances, pronounced mildness, sometimes significant rainfall and a high risk of fog, followed by a gradual transition towards cooler or fairly cold conditions in early February.
From Tuesday 27 to Saturday 31 January: mild, wet and foggy
Tuesday 27 January
Cloud cover will increase with sometimes heavy rain (6 to 22 l/m²), locally preceded by sleet in the High Ardennes.
Conditions will become rather windy, with gusts of 40 to 60 km/h from the southeast to south.
The following night will see widespread fog, locally dense.
Wednesday 28 January
Despite continued mild temperatures, morning fog will be slow to clear. Rain will mainly persist south of the Sambre–Meuse axis.
The night will again be very misty across large parts of the country.
Thursday 29 January
Mild conditions continue, with some brighter spells developing during the day.
Further rain is expected overnight, mainly across the southwestern half of the country.
Friday 30 January
A very mild day with often extensive cloud cover and frequent rain or showers (4 to 19 l/m²).
Saturday 31 January
Mild conditions persist. At times, heavier precipitation will mainly affect the eastern half of the country, while elsewhere skies remain very cloudy.
Likely trend: gradual return to more wintry conditions
From Sunday 1 February onwards, the atmospheric pattern will gradually evolve towards a more marked cooling.
- Sunday 1 February: still mild, but generally dry
- Monday 2 February: a return to more seasonal conditions, with possible sleet in the High Ardennes
- Tuesday 3 to Sunday 8 February:
→ establishment of cooler weather
→ alternation of rain in lowlands and snow or sleet in the Ardennes
→ increasingly wintry feel, without severe cold
Summary
Belgium will first experience a mild and wet end to January, characterised by rain, wind and frequent fog.
Early February will gradually turn cooler and more unsettled, with regular snowfall over the Ardennes and stronger contrasts between lowlands and higher elevations.

Outlook anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Weather Update – 25 January 2026
The period from 9 to 15 February is expected to be marked by enhanced low-pressure activity across much of Europe. Forecast models indicate a southward push of cold, potentially unstable air from the Norwegian Sea and Scandinavia towards the British Isles and the countries bordering the North Sea.
At the same time, significantly milder air from the south-west is likely to continue affecting the Iberian Peninsula, Italy and the Balkans, creating a pronounced thermal contrast across the continent.
During the second half of February, the overall pattern may become increasingly influenced by a gradual expansion of the Russian anticyclone towards northern Scandinavia, alongside a progressive retreat of low-pressure systems towards the Atlantic. This setup would favour a northward advance of mild southern air into France and the Alpine regions, while colder conditions persist over Scandinavia and northern parts of the British Isles.
Between these two air masses, a dynamic and disturbed transition zone could develop close to our regions, pointing towards unsettled weather, highly sensitive to small shifts in the tracks of the low-pressure systems.

Weather Outlook for 3-4 weeks
Update 23-1-26
Period from 7 to 15 February: a possible return to seasonal conditions
As the Atlantic storm track gradually slows, weather conditions may begin to settle. Fewer disturbances would affect the region, allowing for more frequent and sometimes prolonged sunny intervals.
A strengthening influence of high pressure over northeastern Europe would favour more stable and drier conditions, with temperatures returning closer to seasonal norms. A calm, seasonably cool winter pattern may take hold.
Week from 16 to 22 February: a more wintry atmosphere returning?
These longer-range signals should be interpreted with caution, yet they hint at a potential re-establishment of more distinctly wintry conditions. Dry cold air could once again dominate, often accompanied by typical low-level phenomena such as persistent fog, extensive low cloud cover and pronounced temperature inversions.
A subdued but tangible winter atmosphere could then settle across the region.

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.
