(These forecasts are generally updated daily)
Update – 30 January 2026 | 9am
Belgium’s national thermal index is currently trending upwards. Up to 8 February, values are expected to fluctuate within a generally positive range between +1 and +5.
Daytime maxima will range from 6 to 13°C during the mildest days, and from 3 to 10°C during less favourable periods. Night-time minima will lie between 1 and 8°C during the mildest nights, and between -1 and +6°C during cooler nights.
From 8–9 February onwards, a marked decline in the national thermal index is anticipated, with a minimum of around -4 to -5 possible by 11–12 February.
During this phase, daytime highs will range between 0 and +7°C on the less cold days, and between -4 and +3°C on the coldest days. Night-time lows will vary between +3 and -4°C during the least cold nights, and between 0 and -8°C during the coldest nights.

General Weather Evolution for the Next Days
Europe: Analysis & Forecast maps
UPDATE – 30 January 2026 | 11:00
A southerly to south-easterly airflow, mild to very mild in nature, will establish itself over our regions during the weekend and is expected to persist until the middle of next week.
This air mass, largely originating from the Alpine region, northern Italy and the north-western Balkans, will be temporarily disrupted on Tuesday.
Thereafter, the flow is likely to veer more towards the south-east and then east, accompanied by a gradual reduction in mildness.
Likely evolution for the period 9–13 February
The possible development of an anticyclonic area over Greenland, extending towards Scandinavia, combined with a low-pressure system over the northern Mediterranean basin, could favour the establishment of a continental easterly to north-easterly flow.
Such a pattern would allow markedly colder air to spread towards our regions.
In this context, occasionally wintry precipitation in the form of snow or sleet could occur, initially over the Ardennes relief and potentially later also across lowland areas.

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.
