Summer Heat Returns: How Long Will the Warm Weather Last?

Temperatures are set to climb toward a peak of 28 degrees Celsius by Saturday, followed by a cooling trend and rainfall on Sunday.

Temperature Trends and Mid-Week Shifts

The current weather cycle began with cloud cover, though evening skies cleared significantly according to Hagedoren. Nighttime conditions are expected to bring low-hanging clouds from the north, increasing the likelihood of scattered showers. In the Ardennes, localized mist may develop, with temperatures ranging between 7 and 16 degrees Celsius.

Thursday will remain overcast, but conditions are forecast to improve throughout the day. While the morning may bring light drizzle, the KMI expects clearing skies by the afternoon, pushing temperatures up to 24 degrees Celsius.

Pro Tip: When planning outdoor activities for the weekend, aim for Saturday midday to take advantage of the peak sunshine.

Friday is expected to be a transition toward warmer, more stable weather. Hagedoren forecasts a “pleasant” day with temperatures increasing by one degree compared to Thursday. The trend continues into Saturday, which is expected to be mostly sunny with highs reaching 27 to 28 degrees Celsius.

However, this period of warmth will be short-lived. A new weather system is projected to arrive on Sunday, bringing rainfall and cooler air. According to the KMI, the exact volume of precipitation remains uncertain, but maximum temperatures are expected to drop to 23 degrees Celsius.
