January redefines the tee-sheet in Green Bay. With an average high of just 29°F — the coldest month of the year — course availability drops to near zero for outdoor play, and your booking strategy shifts entirely. Most area courses are closed, those that do operate have minimal staffing, and same-day or walk-on play may actually be easier to secure than a reserved slot simply because demand is that thin. That said, don't assume openings; confirm before you drive.
The 13°F daily swing (high 29°F, low 16°F) means early morning tee times are genuinely dangerous in terms of footing and club grip. If any outdoor round is attempted, aim for midday windows when temps briefly peak. Wind averages 11.2 mph — the 3rd-calmest reading of the year — so at least that variable works slightly in your favor.
Because most Green Bay-area courses are closed or operating on skeleton schedules in January, call ahead to verify operation before booking — online tee sheets are often not updated to reflect winter closures. If you do find an open course, midday slots (11 AM–1 PM) give you the best chance of reaching that 29°F daily high before temperatures drop again. See how conditions rate hour by hour on our playability scale.
January's average high of 29°F is 6°F colder than December's 35°F, making it the harder month to find playable outdoor conditions even though both months share the same 11 precipitation days. February edges slightly warmer at 31°F but brings windier conditions (12.7 mph versus January's 11.2 mph) and 2 fewer precipitation days. If you're weighing a late-winter round, February's marginally higher temperatures come at the cost of increased wind.

A small number of facilities with indoor simulators or heated ranges operate through January, but nearly all outdoor courses in the Green Bay area are closed when average highs sit at 29°F. Your best approach is to call specific courses directly, as online booking systems often don't reflect mid-winter closure status.
January's peak wind averages 11.2 mph, which is actually the 3rd-calmest reading of any month in Green Bay and 0.8 mph quieter than December. That places it in the moderate range by site standards, though combined with a 29°F average high, even moderate wind accelerates heat loss significantly and makes any outdoor round physically demanding.
