Wisconsinites will have another opportunity to catch a glimpse of the spectacular northern lights on December 16 and 17, 2025. According to the NOAA’s Space Weather Prediction Center, the aurora borealis is expected to be visible across the northern region of the state on the 16th, with a broader chance for the entire state to see the phenomenon the following day.
The forecast indicates a Kp index of three for December 16 and a heightened level of five for December 17. The SWPC explains that this range typically corresponds with brighter and more active auroras, particularly when they are farther from the poles.
Weather conditions will play a significant role in visibility. As per the National Weather Service, partly cloudy skies are expected in areas like Wausau and Stevens Point on December 16, which could enhance viewing opportunities. However, residents in Green Bay and Appleton may encounter mostly cloudy skies, potentially hindering their experience. On December 17, storms could create additional challenges, particularly in Green Bay, Appleton, and Milwaukee.
To maximize viewing chances, the SWPC recommends watching for the northern lights during the peak hours of 10 p.m. to 2 a.m. While some auroras may be visible earlier or later, they are usually less vivid during those times. It is also advisable to escape the bright lights of the city and seek elevated spots for better visibility.
For those eager to witness this natural spectacle, Wisconsin offers several prime locations that may provide the best views of the night sky. With optimal conditions and a little patience, locals and visitors alike might be treated to an unforgettable display of the northern lights.
