August in Ann Arbor is the month where tee-sheet decisions carry real consequences. With the University of Michigan football season kicking off late in the month, weekend tee times disappear faster than any other time of year — book at least two weeks out for Saturday and Sunday morning slots, and consider weekday rounds if your schedule allows. The weather itself is broadly playable: an 81°F average high sits right at the upper edge of the ideal range, the 63°F low means early morning rounds are comfortable rather than cool, and the 9.5 mph peak wind is the calmest of the year.
The catch is the rain. August ties April as the wettest month of the year at 16 precipitation days, so a tee time that looked fine the night before can turn soggy by the back nine. Build buffer time into your booking window so you can shift to a backup day if needed. Afternoons tend to see more convective storms than mornings, which gives early tee times a practical edge beyond just pace of play.
Michigan home football games begin in late August and immediately compress weekend availability across every public course within 30 miles of Ann Arbor — check the athletic schedule before you book and avoid same-day windows around game times. Early weekday mornings offer the cleanest combination of low wind, moderate temps, and open tee sheets for the entire month. See how conditions rate hour by hour on our playability scale.
July and August are nearly identical on temperature — just a 1°F difference in average high — but August adds one more rainy day and is marginally calmer on wind at 9.5 vs 9.6 mph, making the two months functionally the same in feel. September is the sharper contrast: the average high drops 7°F to 74°F, precipitation days fall by five to just 11, and wind nudges up slightly to 10.2 mph, making it a noticeably drier and cooler month overall. If your priority is avoiding rain, September wins; if you want the warmest window still available, August is your last real chance.

August is warm and the winds are the calmest of the year at 9.5 mph, which helps scoring conditions. The main drawback is that it ties April for the most rainy days in the year at 16, so you should expect at least one weather disruption per trip and book with flexibility in mind.
The Wolverines typically open their home schedule in late August, and that immediately tightens weekend tee-time availability at courses across the area. Booking two or more weeks in advance for any Saturday or Sunday round is advisable, and rounds on game days may also see slower cart and parking access near town.
