May in Ann Arbor, MI: shoulder season for golf — playable with smart tee time selection. Best tee times: mid-morning through early afternoon.
| Average May Weather | |
|---|---|
| Avg daily high | 69°F |

| Rainy days | 14 / mo |
| Avg peak wind | 11.3 mph |
May's numbers in Ann Arbor land in a useful middle ground, but what they actually mean on the scorecard takes a bit of unpacking. A 69°F average high sits comfortably inside the 60–80°F ideal range, so midday rounds should feel natural and free of the grip-tightening cold that lingers into April. The catch is the 20°F daily swing: a 49°F low means morning tee times can start 11 degrees below that ideal floor, stiffening muscles and costing a club or two of distance early in the round. The 11.3 mph peak wind is the 5th-calmest reading of the year, so wind rarely becomes a serious club-selection problem, but 14 precipitation days — tied for 3rd-wettest — means roughly one in every two days carries a real chance of a rain delay or a soft, plugging fairway that kills roll.
Practically, that soft turf cuts both ways. Approach shots hold greens more reliably, which rewards aggressive iron play. Fairway lies, though, can be unpredictable early in the month when the ground is still saturated from April. Plan to add a club on longer approaches if the course is playing wet, and budget extra time for a possible brief shower mid-round.
Book tee times between 10 AM and 1 PM when the temperature has had time to climb from the chilly 49°F low toward the 69°F high — that window consistently puts you closest to the ideal playing range. Given 14 precipitation days, check a short-range forecast the evening before and keep a mid-week alternate date in mind, since weekday slots in May stay more available than June openings. See how conditions rate hour by hour on our playability scale.
April averages 57°F and 16 precipitation days, so May's +12°F jump and two fewer wet days represent a meaningful step toward reliable conditions. June offers another +11°F gain and nearly identical precipitation at 14 days, making it slightly warmer but not appreciably drier. The practical difference between May and June is mostly in that morning low — June's 60°F floor keeps the entire round in the comfort zone in a way May's 49°F mornings cannot.

Midday temperatures averaging 69°F are comfortable for most golfers, but morning rounds starting near the 49°F low can feel genuinely cold and will reduce carry distance by several yards per club. If you're sensitive to cold starts, waiting until 10 AM or later largely solves the problem. Afternoon rounds in late May routinely feel like ideal playing conditions.
With 14 precipitation days across the month, roughly half of all days see some measurable precipitation, making May one of Ann Arbor's wetter months alongside June and October. That doesn't mean every round gets rained out — many events are brief showers rather than all-day rain — but carrying rain gear and building flexibility into your schedule is practical, not overcautious. Watching a 24-hour radar forecast the night before will catch most meaningful threats.
