Golf in Ann Arbor in September threads a narrow window between summer's lingering heat and October's rapid cooldown. Afternoon rounds are comfortable without the humidity that can linger into August. The surprise isn't that fall golf is good here — it's that September specifically beats the warmer months on nearly every measurable condition that affects a round.
Book afternoon tee times — ideally between noon and 2 PM — to let temperatures climb past the cool 56°F mornings before you reach the first tee. September's low precipitation-day count means last-minute openings are less common than in summer, so locking in times a week or two out is worth doing.
