The latest green bay weather update shows a deep and persistent cold settling over Green Bay, with temperatures far below seasonal averages as of December 7, 2025. Early-morning readings hovered near 11°F, and wind chills pushed conditions into even colder territory. Skies started mostly cloudy before clearing into occasional sunshine by afternoon, but the frigid temperatures remained the defining feature of the day.
Cold air continues to dominate the region. Morning temperatures climbed only slightly into the mid-teens. By early afternoon, the city saw brief moments of sun with highs reaching the upper teens. As the sun set, temperatures dropped rapidly, with single-digit lows expected. This pattern aligns with ongoing cold across the central and northeastern United States, creating a widespread early-winter deep freeze.

Current Conditions in Green Bay
Residents woke up to bitter conditions. Morning temperatures ranged from 15°F to 17°F. The afternoon brought a short break in cloud cover, but highs stayed near 18°F to 19°F. The air remained dry and sharp, and even light winds made the cold feel more intense. By evening, temperatures began a steep decline, moving toward the coldest readings of the day.
These temperatures are well below what Green Bay typically experiences in early December. Overnight conditions continue to test the region, bringing risks of frostbite, slippery surfaces, and frozen infrastructure.
This Week’s Forecast: Persistent Cold and Light Snow
The cold trend is expected to continue through the week. Light snow is forecast to develop later today, although totals should remain minimal, generally under an inch. Daytime highs through the coming days will range from the low to mid-20s, still noticeably lower than the city’s usual December averages.
Nighttime lows will fall near or below zero at times, increasing the need for caution. These conditions can harden road surfaces, freeze pipes, and heighten the dangers associated with prolonged outdoor exposure.
Light snow showers may return midweek. Accumulation should remain modest, but visibility issues and slippery roads can still create hazards during commutes.
How This December Compares to Normal Conditions
Green Bay typically sees highs in the mid-30s and lows in the low 20s during early December. This year stands out as significantly colder. A recent daytime high of only 12°F broke a decades-old record for early-month temperatures. The broader climate data shows that while cold snaps are not uncommon, this particular stretch is among the more severe early-December events in recent years.
Snowfall also begins increasing throughout December as cold conditions take hold. With temperatures staying well below freezing, snow that does fall is likely to stick, contributing to a gradually building seasonal base.
Safety Considerations for Residents
With temperatures this low, safety becomes a top priority. Here are key reminders for anyone in the region:
- Dress in layers with insulated jackets, gloves, and hats.
- Limit outdoor exposure and monitor young children and older adults for signs of cold stress.
- Keep pets indoors as much as possible.
- Use caution on roads, especially on bridges and overpasses where ice forms first.
- Protect your home by insulating exposed plumbing and allowing faucets to drip during extreme cold.
Sports fans and event-goers should also take note. Outdoor gatherings can feel drastically colder than the actual air temperature when wind chill factors in. Those heading to evening or nighttime events should prepare for conditions in the single digits or lower.
What to Expect Moving Forward
The current weather pattern indicates that the cold will remain for several days. Additional light snow chances may develop midweek, but major winter storms are not currently expected. Even so, the combination of sustained cold and light snow can still create travel delays and daily challenges.
Seasonal models suggest snowfall will gradually increase throughout the month, consistent with typical December trends. Because temperatures remain well below freezing, any new snow will likely linger. Drivers should plan for icy stretches, especially during early-morning and late-evening hours.
Residents should continue checking updated forecasts daily, as rapid changes in winter conditions are common. Small temperature shifts can quickly influence road safety, visibility, and overall comfort.
