Precipitation is the defining variable for golf in Green Bay in May. With 14 rainy days on average — tied for the third-wettest month of the year — you can expect roughly one wet day in every two rounds you schedule. That reality shapes everything: course conditions, tee-time flexibility, and how seriously you should monitor the forecast before heading out.
The silver lining is that the temperatures finally make outdoor rounds comfortable. Highs average 67F, which lands squarely in the ideal 60-80F window, and peak winds ease to 12.4 mph compared to April's 13.7 mph. The 19F daily swing between the 48F low and 67F high means early morning rounds still call for an extra layer, but afternoon windows can be genuinely pleasant. Think of May as Green Bay's re-entry month: the course is open, the air is warm enough, and the main variable you're managing is rain.
With 14 precip days spread across the month, checking hourly forecasts the night before is worthwhile so you can shift your tee time if showers are forecast. Booking courses with flexible rain-check policies adds useful insurance when nearly half of May days carry some precipitation risk. See how conditions rate hour by hour on our playability scale.
April is noticeably colder and windier — a 13F lower average high, 16 precip days instead of 14, and gusts averaging 1.3 mph stronger — so May marks a real step forward in playability. June closes the remaining gap, gaining another 12F on the high and trimming one more precip day while winds barely budge at just 0.2 mph calmer. May sits exactly between those two months: warmer and drier than April, but still short of June's reliability.
