DECORAH — According to local meteorologist and Luther College faculty member Richard Bernatz, June 2025 was a decidedly warm month in Decorah, continuing the trend of above-average temperatures observed over much of the past year. The average temperature for June settled at 72.9 degrees, a significant 4.6 degrees warmer than the historical average. This placed June 2025 among the top 10 warmest Junes on record, ranking as the eighth warmest since 1894. The warmth was particularly pronounced in the overnight lows, with three consecutive days—the 21, 22 and 23—setting new record warmest 24-hour minimums. While the month saw a peak temperature of 94 degrees on the 22nd, the coldest mornings dipped to 41 degrees on the 10 and 11. The consistent warmth led to a notable increase in cooling degree days, indicating a greater demand for air conditioning. In terms of precipitation, June 2025 was a wetter-than-average month for Decorah. A total of 6.26 inches of rain fell, exceeding the historical average by 1.47 inches. This precipitation was spread across 15 days, a higher frequency than the typical 10 to 11 days with measurable rainfall. The most substantial downpour occurred on the 15th, bringing 1.79 inches in a 24-hour period. Looking back at the past 12 months, the trend of warmth remains a dominant feature, with 11 out of the last 12 months experiencing above-average temperatures. Remarkably, four of the past 12 months rank in the top 10 warmest for their respective monthly histories. Precipitation-wise, while seven of the past 12 months were technically drier than average—with January and September ranking as the driest and second driest in their respective histories. A closer look reveals a recent shift. Three of the last four months have seen above-average precipitation, suggesting a possible transition to a wetter pattern following some drier periods. The precipitation deviations over the past year show a slight deficit overall, but the recent trend in the last few months points toward more moisture. Never a dull moment!
