Update – 24 January 2026 | 9 a.m.
Belgium’s national thermal index is on a clear downward trend and is expected to reach its lowest point on Monday, 26 January, with values between –3 and –4. This will result in daytime temperatures ranging from –2 to +4°C, while night-time lows will fall between –5 and +1°C, depending on the region.
This cold snap is expected to be short-lived. Towards the end of the week, temperatures will gradually rise, with the thermal index peaking around +3 to +4 on 30 and 31 January. Daytime maxima will then reach 5 to 11°C, while minimum temperatures will generally range between 1 and 7°C, depending on elevation.
In early February, conditions are likely to stabilise around thermal neutrality. Temperatures should return to seasonal averages, with maximum values of 2 to 8°C and minimum temperatures between –2 and +4°C, depending on location.

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.

Analysis based on the BMCB multi-model approach
(operational runs and ensemble guidance from ICON, AIFS and ECMWF)
A disturbed end to January, with a persistently unsettled start to February
The upcoming period is expected to be rather variable, alternating between colder spells, temporary mild interludes and a succession of often active weather systems. Precipitation, at times abundant, will remain a key feature, while snowfall will continue to affect the higher elevations of the Ardennes on occasion.
From Monday 26 to Friday 30 January
Monday 26 January
Conditions will remain fairly cold and often very cloudy. Persistent fog and low stratus will dominate the lowlands, while brighter spells will be more frequent over southern Ardennes and locally elsewhere. Precipitation will remain limited. During the following night, fog will once again expand south of the Sambre-and-Meuse axis.
Tuesday 27 January
An active frontal system will move across the country. Cloud cover will quickly increase, bringing sometimes heavy rain, locally preceded by sleet over the higher Ardennes. Winds will strengthen noticeably, with south-easterly to easterly gusts reaching 40 to 60 km/h.
Wednesday 28 January
A temporary mild spell will develop under mostly cloudy skies, with some brighter intervals, especially over western Flanders. A fairly strong southerly wind will produce gusts of 50 to 70 km/h. During the evening and overnight, clearer spells will gradually spread inland.
Thursday 29 January
Seasonal conditions will persist, with passing brighter spells. However, further rain is expected during the night, with a temporary risk of sleet over the Ardennes summits.
Friday 30 January
Very mild but distinctly unstable weather will prevail, with numerous showers, some of them heavy. Southerly to south-westerly winds will remain a prominent feature, with gusts of 40 to 60 km/h.
Likely trend: Saturday 31 January to Saturday 7 February
Late January and early February are expected to remain under the influence of a disturbed Atlantic flow.
Temperatures will most often stay close to or slightly above seasonal averages, while precipitation will be frequent and at times heavy. Rain will dominate across the lowlands, whereas the higher Ardennes will regularly experience episodes of snow or sleet, particularly between 2 and 7 February.
Winter conditions will therefore remain largely confined to higher ground, within a persistently damp and often grey weather pattern across the country.

Outlook anomalies at 500 hPa
(mid-troposphere = 5,000–6,000 m altitude)
Update – 23 January 2026
Around the transition from the first to the second ten-day period of February, the atmospheric pattern is expected to remain dominated by a broad low-pressure system, with its disturbed axis stretching from the Atlantic across northern France into Central Europe. Our regions would lie along its northern flank, temporarily exposed to a continental north-easterly to easterly flow, bringing cooler air and a more distinctly wintry character.
Towards the end of the second ten-day period and during the third, a gradual change in the weather regime is likely to emerge. The retreat of the low-pressure system towards the nearby Atlantic, combined with the strengthening of a large anticyclonic area over the central and eastern Mediterranean and Eastern Europe, would promote the northward advection of significantly milder but still fairly unsettled air from France into our areas.
This milder trend is expected to persist into early March. Reduced low-pressure activity over the Atlantic and the continued dominance of high pressure across the Mediterranean would then favour a more stable atmospheric setup, characterised by milder temperatures and a noticeably less wintry and less humid feel.

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.
