December marks the sharp drop-off from an already-cool November in Green Bay. The average high falls to 35°F — down 11 degrees from November's 46°F — pushing most rounds firmly into cold-weather territory. With a low of 22°F and a daily swing of only 13°F, temperatures rarely recover enough during the day to feel comfortable without serious layering. Frost on greens and firm, unforgiving fairways are the norm rather than the exception.
That said, December is tied for the second-driest month of the year at 11 precipitation days, and peak wind settles at 12 mph, making it the fifth-calmest month. If you're determined to play, you won't be fighting constant rain or heavy gusts — just relentless cold. Courses that stay open typically do so only early in the month before hard freezes set in for good.
Book the earliest available tee time on days forecast above 33°F, when frozen greens are most likely to have softened slightly — mid-morning slots around 10–11 AM tend to catch the day's peak warmth near that 35°F average high. Availability won't be the issue in December; course closures will be, so call ahead before making any plans. See how conditions rate hour by hour on our playability scale.
December sits 11°F colder than November in average high, a gap wide enough to turn what was a chilly but manageable round into a genuinely difficult one. Heading into January, the high drops another 6°F to 29°F, with the low falling to 16°F, so December is actually the more playable of the two winter months — though that's a low bar. Precipitation days hold steady at 11 through both December and January, and winds ease slightly each month, dropping 1.2 mph from November into December and another 0.8 mph into January.

Some courses stay open through early December if the ground hasn't fully frozen, but most close before mid-month as temperatures settle around a 35°F high and 22°F low. Call ahead, because conditions can change quickly and posted hours don't always reflect actual playability. By late December, open courses are the exception rather than the rule.
Expect an average high of 35°F and an average low of 22°F, with a daily swing of only 13°F — meaning temperatures stay cold all day with little afternoon relief. Wind averages a peak of 12 mph, which at those temperatures pushes the feels-like reading well below freezing throughout most of a round. Proper insulation and wind protection aren't optional; they're necessary gear.
