August in Green Bay, WI: shoulder season for golf — playable with smart tee time selection. Best tee times: morning before noon for the most comfortable round.
| Average August Weather | |
|---|---|
| Avg daily high | 80°F |
| Avg daily low | 63°F |
| Rainy days | 14 / mo |
| Avg peak wind | 10.8 mph |
August in Green Bay holds an unusual tension: peak-wind readings of 10.8 mph make it the second-calmest month of the year, yet 14 precipitation days tie it for third-wettest on the calendar. Those two facts don't usually travel together, and they shape every round. The 80°F average high and steady 63°F low keep temperatures squarely in the comfortable range, but rain is a near-daily planning factor rather than an occasional nuisance.
The 17-degree daily swing from low to high is worth noting for tee-time decisions. Early morning starters will want a light layer that they can shed by the back nine, since the day warms considerably between a 6 AM start and noon.
Book morning slots specifically to front-run the afternoon convective showers that dominate August's 14 precipitation days — courses fill fast on clear-morning forecasts, so lock in tee times three to five days out and check radar the night before rather than relying on the weekly outlook. See how conditions rate hour by hour on our playability scale.
July and August are nearly identical in feel — August's average high drops just 2°F to 80°F, the low holds steady at 63°F, and you actually get one fewer rainy day than July's 15. The real transition happens when you move into September, which sheds 7°F off the average high and drops two more precipitation days, offering a drier and noticeably cooler round that many locals prefer for fall conditions.

August averages 14 precipitation days, tying it with March and May as the third-wettest month of the year — so roughly half the days see some measurable rain. Most of that comes as short afternoon showers rather than all-day soakers, which makes morning tee times a practical workaround. Flexibility in your schedule and a rain jacket in the bag are the two most useful tools.
At an average high of 80°F, August is Green Bay's second-hottest month but stays well within the comfortable playing range. The low of 63°F means mornings are genuinely pleasant, and the peak wind of 10.8 mph — the second-calmest of the year — keeps things from feeling stagnant even on the warmest afternoons. Heat is not the problem in August; rain is.
