On August 1st, 2025, the Rhine River at the Basel-Kleinhüningen station recorded a daily mean discharge of 1,581 m³/s. The minimum discharge was 1,437 m³/s, and the maximum reached 1,731 m³/s. These values place the current day's flow in the upper range of historical data for August, with the maximum discharge at the 86th percentile and the minimum at the 88th percentile for all available records of this month. Neither the maximum nor the minimum discharge ranks among the top or bottom 10 historically for August, indicating that while the flow is above average, it is not exceptionally high or low.

Over the past 30 days, the Rhine has shown significant variability in discharge. The highest discharge during this period was 2,161 m³/s, recorded on July 29th, while the lowest was 514 m³/s on July 4th. This range suggests dynamic hydrological conditions, with fluctuations likely influenced by upstream weather patterns or seasonal changes. The variability in discharge over the past month has been considerable, with a difference of over 1,600 m³/s between the highest and lowest values.

In a broader historical context, comparing today's discharge with all August values since the start of measurements, the long-term average discharge for August is approximately 1,212 m³/s. The historical minimum and maximum for August are 220 m³/s and 3,729 m³/s, respectively. Today's mean discharge of 1,581 m³/s is above the long-term average, indicating a relatively high flow for this time of year, though it remains well below historical extremes.

Overall, while the current discharge levels are elevated compared to historical averages for August, they do not represent a significant anomaly. The data suggests a continuation of the recent trend of higher-than-average flows, likely driven by recent climatic conditions affecting the Rhine's watershed.
