Weather Update – 8 April 2026
Conditions will remain largely dry over the next 42 hours, with little or no rainfall expected: none north of the Scheldt, 0 to 1 L/m² between the Scheldt and the Sambre–Meuse axis, and only 0 to 4 L/m² further south.
Wednesday will be very sunny. The morning features clear skies with light to moderate easterly to southeasterly winds. The afternoon remains bright with a few high clouds spreading from the north. Highs will reach around 21°C along the coast and 23 to 24°C inland, with 19 to 24°C across the higher Ardennes.
The evening and following night will remain clear to partly cloudy. Winds will ease further, with lows near 9°C at the coast, 5 to 11°C inland, and locally close to freezing in some valleys.
Thursday begins sunny with some high cloud, particularly in the east and south. During the afternoon, conditions remain mostly bright, though southwesterly winds will increase. Highs around 18°C at the coast and 20 to 25°C inland.
By evening, cloud cover increases with a slight risk of light showers over the eastern half of the country. Southwesterly to westerly winds become more noticeable, with gusts of 30 to 40 km/h, especially across Flanders.

Update 8 April 2026
The mild peak expected on 9 April will mark the most pronounced phase of the period, with the national thermal index reaching +6 and daytime temperatures ranging between 18 and 25°C across Belgium.
This increase will be short-lived. In the following days, the thermal index will drop quickly and then fluctuate between -1 and +3, a pattern likely to persist at least until 22 April.
Within this more moderate regime, maximum temperatures will generally range between 14 and 21°C on the mildest days, while cooler intervals will typically see values between 9 and 16°C.

Update 8 April 2026
A cold front will reach Ireland on Wednesday before moving towards our regions on Thursday. It will cross the country with a temporary and not very active spell of rain. 🌧️
Behind it, a noticeably cooler air mass will settle in on Friday. This will quickly stabilise as a high-pressure cell near 1019 hPa builds in, bringing a relative lull with some clearer spells. 🌤️
However, this improvement will be short-lived. A more active disturbance is expected on Saturday, bringing more significant precipitation. 🌦️
Thereafter, a sometimes unstable maritime flow will dominate for several days, maintaining moderate temperatures with occasional rain or showers. 🌬️🌥️
Likely outlook for 14–22 April:
High pressure should extend across much of northern Europe and begin to steer continental air towards our regions. Conditions are expected to become more stable and drier after 15 April, with temperatures also turning milder.

Update 8 April 2026
Trend based on the BMCB multi-model (ICON, AIFS, GFS, ECMWF)
After a contrasting late-week period, including a more active disturbance on Saturday, conditions will remain changeable into early next week. Friday will be cooler but dry, with a mix of cloud and sunny intervals. On Saturday, a disturbance arriving from the west will bring sometimes significant rainfall in still relatively mild and windy conditions, with southeast gusts of 30–50 km/h.
On Sunday, cooler air spreads across the country with mostly cloudy skies and lingering rain in the east. Early next week remains unsettled, with cloud and showers, more frequent on Tuesday.
From midweek onward, a gradual improvement is expected. Precipitation will become lighter and more sporadic, while conditions turn drier. Between 16 and 22 April, generally mild weather should dominate, with little or no rainfall and increasing anticyclonic influence

Update 4 April 2026
Weather outlook from 20 to 27 April 2026
The latest medium-range projections indicate the persistence of a broad high-pressure block extending from the polar regions towards Scandinavia and the northern British Isles.
At the same time, low-pressure conditions are expected to persist between the Azores and Morocco.
In this setup, our regions would lie along the southern flank of the anticyclone, under the dominant influence of an easterly to northeasterly flow. This configuration would favour the establishment of a dry and mild air mass.
Rainfall and thunderstorm activity would mainly concentrate further south across Europe, particularly over southern and eastern Spain, much of the Canary Islands and the Maghreb, while conditions across our regions would remain generally more stable.

Weather Outlook for 3-4 weeks
Weather Trend – Update of 2 April 2026
Onset of a spring-like pattern toward the end of April
According to the latest projections, the period from 20 to 26 April could mark the return of more spring-like conditions across our regions. Temperatures are expected to be close to seasonal averages, with an overall pleasant feel. Sunshine and cloud intervals should alternate within a prevailing southwesterly flow, favourable for the development of the first localized convective instability.
For the week from 27 April to 3 May, this tendency toward rather pleasant weather could be confirmed. Temperatures would remain near to slightly above normal, with an anomaly of around 0 to +1°C. Early May would therefore be fairly mild, though occasionally unstable, with a risk of thundery showers. The precipitation outlook remains more uncertain at this stage.

Weather Outlook for 3 months
Update – 25 March 2026
La Niña weakening, El Niño possible for summer
Ocean-atmosphere indicators in the tropical Pacific show that La Niña is gradually fading, with neutral conditions expected during spring. Multi-model projections suggest this pattern could favor the emergence of an El Niño event during summer.
This transition may lead to a more variable atmospheric circulation, influencing precipitation and temperature patterns across several regions, including Europe. As a result, the weather signal becomes more volatile and less predictable.
April: often influenced by anticyclonic conditions, turning relatively dry. Temperatures near to slightly above normal (+0.5 to +1°C). Risk of late frost early in the month. Below-normal rainfall.
May: stable and rather dry. Temperatures around +1°C above normal. Frequently pleasant conditions. Slight rainfall deficit.
June: potentially warm start to summer with frequent thunderstorm development. Temperatures +1 to +1.5°C above normal. Highly variable rainfall with strong regional contrasts.
