Precipitation in Northeast Wisconsin in June, early July

(WFRV) – Typically, June is the wettest month in Northeast Wisconsin, with an average monthly rainfall of 4.10 inches. In June 2024, many communities surpassed that number, some by a large margin.

Below is a graph showing the ten stations that reported the highest rainfall amounts this past June. Hilbert led the way with a tenth of over 10 inches of rain for the month. Not included in the top ten, Oshkosh and Appleton recorded just over 7 inches of rain, Manitowoc about 6.5 inches, and the Green Bay Airport reported just over 4.5 inches.

For comparison, in June, the Green Bay Airport recorded rain on seventeen out of a possible thirty days. Adding in trace amounts, or days where less than 0.01 inches of rain fell, gives a total of twenty rainy days. That’s about 50-66% of the days in June that it rains, or about every other day!

If you thought the incessant rain was going to stop, the beginning of July had other plans. A system moved in on Tuesday afternoon and lingered until the early hours of Wednesday morning.

Heavy rains swept through Green Bay and the Fox Valley down to Fond Du Lac, causing rivers to overflow and adding more rain to ground already soaked from the previous month. Below is a graph of the top 10 highest rainfall reports from yesterday.

Oshkosh led the way with exactly 2.5 inches of rainfall, followed by Omro and Fond Du Lac. The weather station here at WFRV reported 1.40 inches of rainfall. Others, including Waupaca, New London, Shiocton, Crivitz, Allouez and Howard, recorded rainfall totals of about 1.8 inches.
