Pull out a short-sleeve polo for an April round in Green Bay and the morning air will correct that assumption fast. The average low sits at 36°F, and even as the high climbs to 54°F — an 11-degree jump from March — the 18-degree daily swing means conditions shift dramatically between your first and last hole. April is also Green Bay's wettest month of the year at 16 precipitation days, and its windiest at a peak of 13.7 mph. That combination of cold mornings, soaked fairways, and gusting wind catches a lot of golfers off guard.
The surprise isn't that April is unplayable — it's that the window to play well is narrower than the calendar suggests. Tee times in the early afternoon, once temperatures have peaked, offer the best chance of conditions that approach comfortable. Expect soft, slow greens throughout the month, and plan your layering accordingly rather than assuming the drive out will feel like May.
Book afternoon slots — ideally starting around 1 PM — to let the temperature climb toward the 54°F daily high before you tee off, since morning lows near 36°F make early rounds genuinely cold. Given 16 potential rain days, check the hourly forecast the morning of your round rather than relying on a multi-day outlook, and keep a same-week cancellation window open if your course allows it. See how conditions rate hour by hour on our playability scale.
March averages a high of only 43°F with 14 precipitation days, so April's 54°F high is a meaningful 11-degree improvement, but the extra 2 rain days and a slight uptick in peak wind (13.7 mph vs. 13.0 mph) mean April is actually wetter and windier despite feeling warmer. May changes the picture substantially — highs jump another 13 degrees to 67°F, lows climb to 48°F, and both rain days and peak wind drop, making it the cleaner month by nearly every measure. If your schedule has any flexibility, even a week into May represents a notable upgrade over late April.

Most courses in the Green Bay area do open in April, but conditions vary week to week. Fairways are typically soft and cart restrictions are common early in the month given 16 average precipitation days and lows still touching 36°F, so call ahead to confirm whether walking-only rules are in effect before you show up.
April is actually Green Bay's windiest month of the year, with peak winds averaging 13.7 mph — approaching the 15 mph threshold where wind starts meaningfully affecting shot shape and club selection for most players. Plan for at least one club of adjustment on exposed holes, and expect those winds to be coldest in the morning when temperatures are still near the 36°F low.
