May in Louisville, KY: variable for golf — mixed conditions — check the live score. Best tee times: mid-morning through early afternoon.
| Average May Weather | |
|---|---|
| Avg daily high | 76°F |
| Avg daily low | 58°F |
| Rainy days | 16 / mo |
| Avg peak wind | 10 mph |
May's numbers look friendly at first glance — a 76°F average high, 10 mph peak winds, and temperatures that sit inside the ideal 60–80°F window for most of the day. But the 18°F daily swing between that 58°F low and 76°F high is the detail that actually shapes your round. An early tee time can play two or three degrees firmer and a club longer than an afternoon slot on the same course. Carry distance, green speed, and even how far your ball rolls out on approaches will shift as the day warms.
The bigger number to respect is 16 precipitation days — the second-wettest month on the Louisville calendar. That does not mean two solid weeks of rain; it means roughly every other day carries some chance of a shower, often brief and afternoon-heavy. Cart-path-only conditions and soft fairways are realistic expectations on a meaningful share of rounds. Plan accordingly: pace of play slows, and that 76°F high can feel raw if a front is passing.
Book a morning tee time — ideally before 9 AM — to take advantage of the lower end of that 18°F daily swing, firmer turf from overnight temperatures near 58°F, and the shorter window before afternoon convective showers develop. Weekday slots fill less quickly than weekends in Derby month, but the two weeks surrounding the Kentucky Derby (first Saturday of May) see Louisville visitors spike, so lock in any Saturday or Sunday rounds well in advance. See how conditions rate hour by hour on our playability scale.
April to May brings a welcome 10°F jump in average high and a slight easing of wind — down 1.7 mph to 10 mph — but adds one more precipitation day, pushing May to 16 versus April's 15. June trims the rain further to 14 days and calms the wind another 0.8 mph, but the average high climbs to 84°F, which nudges conditions outside the ideal scoring range by midday. May sits between a cool, windy April and a hotter, slightly drier June — more comfortable than either extreme, but the wettest of the three.

May offers Louisville's most comfortable temperature window — a 76°F average high that sits squarely in the ideal 60–80°F range — but it is the city's second-wettest month at 16 precipitation days. Rounds are very playable, especially in the morning, but expect intermittent soft conditions and the occasional cart-path-only day. The Variable season-tier badge on this page reflects that trade-off accurately.
Yes, noticeably. The Derby falls on the first Saturday of May and draws large numbers of visitors to the metro area, which tightens weekend tee sheet availability at courses across Jefferson County and the surrounding counties. If your trip overlaps with Derby week, book weekend rounds four to six weeks out and consider weekday alternatives, which remain easier to secure.
