Update of 3 April 2026
Precipitation over the next 42 hours will remain very limited, with totals generally between 0.5 and 2 L/m² across northern and central areas, and locally up to 4 L/m² south of the Sambre–Meuse axis.
On Friday, skies will be mostly cloudy to overcast, with temporary sunny spells in the morning. Light, scattered rain will mainly affect Flanders and western Hainaut during the afternoon before drifting toward central areas. Temperatures will remain modest, around 13°C along the coast, 10–12°C inland and 7–9°C over the higher Ardennes, with a moderate south to southwesterly wind. During the evening and overnight, low stratus and fog will form over the Ardennes, while clearer intervals gradually spread from Flanders. Minimum temperatures will range from about 2°C at the coast to 6–10°C elsewhere.
Saturday will turn milder despite persistent cloudiness. The morning will feature some bright spells under high cloud, while the afternoon remains mostly cloudy with limited sunshine, especially improving from the west and south later. Broader clearings are expected in the evening. Highs will reach around 17°C along the coast, 17–19°C inland and 12–17°C south of the Sambre–Meuse axis, with a moderate southerly wind.

Weather Update – 3 April 2026
The next ten days will be characterised by significant temperature fluctuations. After an initial warming on Saturday 4 April, a noticeable cooling is expected over the Easter weekend, followed by another mild spell around midweek.
Highs will range between 12 and 19°C on Saturday, drop to 9–15°C on Easter Sunday, and rise again to 16–23°C on Wednesday, depending on the region.
Beyond 9 April, the trend suggests a gradual return to temperatures close to or slightly below seasonal averages. Maximum temperatures should then range between 7 and 14°C initially, before a slight increase to 10–16°C after 13 April.

Weather Update – 3 April 2026
A high-pressure system forming north of the Alps on Saturday will shift toward Brittany on Sunday, temporarily bringing milder air to our regions. A weak cold front may nevertheless produce some light rain on Sunday.
On Monday, the high will move to the southern North Sea, establishing a dry and stable continental flow from Germany. This pattern will strengthen in the following days as the high expands toward Scandinavia. Air will gradually become milder, with generally dry conditions.
This more stable spell could be interrupted toward the end of the week by a cold front reaching the British Isles on Thursday and potentially crossing our regions overnight. It would be followed by noticeably cooler and more unstable maritime air. An active low-pressure system may then move from Scotland toward Germany during the following weekend, bringing more unsettled weather again.

Update of 3 April 2026
Based on the BMCB multi-model (ICON, AIFS, GFS, ECMWF)
After a rather cloudy Sunday with occasional light rain and a brisk west to southwest wind, conditions will gradually become more stable. During the following night, winds will ease, clearer spells will develop and local fog may form, especially across Wallonia and the Campine.
From Monday to Wednesday, dry and mostly sunny weather will dominate, with temperatures becoming progressively very mild. Some high-level cloud may pass at times but without significant impact.
On Thursday, mild conditions will persist with sunny intervals, although a band of rain is expected overnight.
From Friday onward, the weather will turn more unsettled. It will become less mild and cooler over the weekend, with periods of rain or showers, locally moderate. This cooler and slightly unstable pattern is likely to continue into early the following week, with generally light and intermittent precipitation.
Around midweek (15–17 April), conditions should remain rather cool and variable, with occasional light rain or showers but no significant rainfall episodes.

Weather outlook from 13 to 27 April 2026: toward more stable spring mildness
The latest medium-range projections suggest the gradual establishment of a large high-pressure block between the polar regions, central Europe and the western Mediterranean during the week of 13–20 April. At the same time, low-pressure areas are expected to develop over northern Egypt and to the west of the British Isles.
In this configuration, our regions would lie along the western flank of the anticyclone, under the influence of a southerly to southeasterly flow. This would favour the advection of mild air, while the most active disturbances would mainly affect the British Isles, the English Channel and northwestern France.
For the period 20–27 April, high pressure would extend from the central Mediterranean towards Scandinavia, then to Greenland and northeastern North America, while a low-pressure system would settle west of Morocco.
This evolution would place much of western Europe under an easterly flow, mild to locally fairly warm and generally dry. Precipitation would become less frequent, with thunderstorm risk mainly confined to the Alps and southeastern France.

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.
