Based on the data provided for April 2026 at the NBCN weather station in Binningen, here is the weather report.

The month of April 2026 was characterized by a near-average average temperature of 12.2 degrees Celsius, which is slightly above the 20-year average of 11.3 degrees. The highest temperature recorded was 23.9 degrees on April 5th, while the lowest temperature dipped to -0.1 degrees on April 2nd. This single frost day on April 2nd was the only day with a minimum temperature below freezing. No summer days, hot days, ice days, or tropical nights were observed. Total precipitation for the month was a mere 23.0 mm, which is significantly less than the historical average of 56.8 mm. The wettest day was April 12th with 8.9 mm of rain, a value that does not exceed the 20 mm threshold for a notable heavy rain event.

In terms of historical significance, April 2026 was not a record-breaking month for temperature. The highest temperature of 23.9 degrees ranks as only the 15th warmest maximum temperature in the last 20 years. The warmest April day on record remains 28.8 degrees, set in 2024. The month's average temperature does not place it among the top three warmest or bottom three coldest Aprils. However, the precipitation story is more notable. With only 23.0 mm of rain, April 2026 ranks as the 14th driest April in the last 20 years. This places it firmly in the drier half of the historical record, but not among the three driest. The driest April on record remains 2007 with just 2.0 mm of precipitation.

Comparing this April to the past 20 years, the most striking feature is the pronounced lack of rainfall. While the temperature was unremarkable, the total precipitation of 23.0 mm is less than half of the long-term average. This dry spell is the most significant deviation from the norm for the month. The previous record for the wettest April was set in 2016 with 144.8 mm, a stark contrast to this year's total.

Overall, April 2026 in Binningen was a month of near-normal temperatures but exceptional dryness, placing it among the drier Aprils of the last two decades.
