Ann Arbor offers university-town golf with a May through October season. Summer provides the best conditions though afternoon storms can develop. Fall is excellent with cooler temperatures and autumn colors.
Ann Arbor's spring and early summer rounds are defined by a 20°F gap between morning lows and afternoon highs — the widest daily swing of any month, shared by April, May, and June. A 7 a.m. tee time at 49°F and a back-nine finish pushing 69°F in May is effectively two different weather days compressed into one round. Cold air compresses a golf ball's core; expect to lose a few yards early in the round that quietly come back as temperatures climb.
That swing shrinks to just 12°F in December and January, but those months are essentially unplayable anyway, with highs only reaching 40°F and 33°F respectively and 15 precip days each. The practical season runs May through October, and within that window the swing ranges from 15°F in October to 20°F in May and June, so dressing for the first tee and dressing for the 18th green are genuinely different decisions.
April brings the widest daily swings of the year — highs of 57°F against lows of 37°F — and 16 precip days, the most of any month. Peak winds average 13.1 mph in April, keeping ball flight lower than you'd expect. Pack a mid-layer and plan for soft, slow fairways through most of April and into early May.
June averages a high of 80°F and a low of 60°F — the low end of the site's ideal range arriving right at sunrise, perfect if you get out early. July's 82°F high is the warmest of the year, and winds drop to 9.6 mph, the second calmest month. With 64°F lows keeping atmospheric moisture elevated, afternoon convective cells can build quickly — morning tee times sidestep that risk better than hoping the radar stays clear.
September is the driest month on the calendar with only 11 precip days, and temperatures ease to a 74°F high and 56°F low. Wind averages 10.2 mph — manageable, though October ticks back up to 11.7 mph as fronts move through more frequently. The 15°F daily swing in October means starting in a jacket and finishing in a shirt is routine.
December highs of 40°F and January highs of 33°F push conditions well below the playable range most days. Lows drop to 20°F in February, the coldest of the year. With 15 precip days in both December and January, frozen or waterlogged ground is the norm rather than the exception.
June through August keeps avg highs between 80–82°F, but peak afternoon temps in July (82°F) and August (81°F) slightly exceed the 80°F ideal ceiling — mornings and evenings, however, remain well within range with lows of 60–64°F. Wind is at its calmest in August (9.5 mph) and nearly as quiet in July (9.6 mph). September extends the good run with the fewest precip days of the year (11) and comfortable highs of 74°F.
In May, lows average 49°F while highs reach 69°F — a 20°F swing across a typical round. Start with a thermal base layer and a wind vest you can strip off by the turn. Gloves are useful for the first few holes even in late May, and they double as a reminder that your ball is flying shorter until the air warms up.
September is the stronger choice on paper: only 11 precip days versus 14 in October, and a 74°F high versus 61°F. October's temperatures can dip to an average low of 46°F and winds pick back up to 11.7 mph as fall fronts arrive. That said, October foliage can make a round feel worthwhile even if scoring conditions are softer.
July logs 15 precip days and August 16, and many of those are short convective storms that build in the afternoon heat. Morning rounds — starting before 9 a.m. — largely sidestep this risk. If you're locked into a midday or afternoon tee time in July, keep an eye on radar; the high lows (63–64°F) keep enough atmospheric moisture around to fuel quick-developing cells.
