Green Bay is in for a significant weather shift as early June brings in more summer-like conditions, with rising temperatures, hazy skies, and even a threat of severe storms midweek. Residents can expect an uptick in both heat and humidity starting Monday, as Wisconsin transitions into a classic early-summer pattern.
According to the National Weather Service (NWS), temperatures will jump sharply to the mid-80s by Monday, accompanied by haze likely caused by wildfire smoke drifting into the region. Those with respiratory conditions or sensitivities are advised to limit outdoor exposure.
Monday Forecast: Hazy Sunshine and High Heat
Monday, June 2, will mark a noticeable change in the atmosphere. Temperatures are expected to climb to 86°F (30°C), the warmest Green Bay has seen in recent weeks. However, the sunshine won’t be crystal clear. Experts say wildfire smoke is the reason for the hazy conditions blanketing the sky.
“This kind of haziness is becoming more common during early summer, particularly when wildfires are active in parts of Canada or the Western U.S.,” said a meteorologist from the NWS Green Bay office. “It affects visibility and can impact people with breathing issues.”
Nighttime temperatures will also be warmer than usual, with lows around 67°F (20°C).
Tuesday Brings Storm Threat
Tuesday, June 3, will see a dip in temperatures but a spike in storm activity. The high is expected to reach 79°F (26°C), but residents should prepare for severe weather by the afternoon. The National Weather Service warns of heavy thunderstorms that could bring flooding downpours, hail, damaging wind gusts, and even the possibility of an isolated tornado.
These storms will be fast-moving and potentially dangerous,” the NWS said in a bulletin. “People should stay updated through weather alerts and have a safety plan.
Mid-Week Relief with Less Humidity
By Wednesday, the humidity will start to drop, bringing some relief after a steamy start to the week. Temperatures will hover around 74°F (23°C) with some lingering haze. Overnight lows are expected around 54°F (12°C).
Thursday’s forecast looks clear and pleasant, with a mix of sunshine and high clouds. The high will be about 76°F (25°C) and the air will feel drier, offering a nice break from the earlier muggy conditions.
Friday continues the trend of comfortable early summer weather, with highs near 73°F (23°C) and mostly sunny skies.
Weekend Outlook: Classic Wisconsin Summer Vibes
As the weekend approaches, the weather remains in line with typical early June conditions in Green Bay. Saturday will be partly sunny and pleasant, with a high of 74°F (23°C) and lows staying in the mid-50s. It’s a perfect setup for outdoor activities, barbecues, and park visits—provided no new storm systems roll in.
Health & Safety Tips for the Week
- Stay Hydrated – As temperatures rise, drinking plenty of water is essential, especially for children and the elderly.
- Limit Outdoor Activity – On hazy or high-pollution days, avoid strenuous exercise outdoors.
- Prepare for Power Outages – With strong storms expected, keep devices charged and flashlights handy.

According to local health officials, those with asthma or heart conditions should be especially alert on smoky days. “Fine particles in the air from wildfire smoke can aggravate chronic diseases and increase the risk of cardiac events,” said a spokesperson from the Wisconsin DHS.
