September's numbers in Sioux Falls line up almost perfectly with what a scorecard wants. The average high of 77°F sits squarely in the 60–80°F ideal window, so heat won't be adding strokes by forcing rushed hydration stops or sapping concentration on back-nine holes. Low temperatures drop to 57°F, a 20-degree daily swing that matters most on early tee times — a morning round can start firm and cool while afternoon rounds play soft and comfortable. Eight precipitation days tie September for the third-driest month of the year, which means firmer fairways, predictable ball flight, and fewer weather delays breaking your rhythm.
Wind is the one variable that keeps September honest. Peak wind of 13.8 mph lands in the moderate range, enough to cost a club or two on exposed holes but not enough to make course management feel like guesswork. Taken together, the stats point to a month where conditions genuinely support scoring — not just tolerable golf, but rounds where the weather is working with you rather than against you.
With only 8 precipitation days and peak winds at 13.8 mph, mid-morning tee times around 9–10 AM let temperatures climb away from the 57°F overnight low before you reach the more demanding stretches of your round. September's Peak season status means local demand stays high through the month, so booking at least a week out — especially for weekend rounds — is worth the effort.

September drops 6°F from August's average high of 83°F, which actually removes the heat stress that can inflate scores late in a summer round, while shedding three precipitation days makes conditions noticeably drier and more consistent. Wind ticks up only 0.8 mph from August, so that variable is essentially unchanged. Looking ahead, October brings a sharp 16°F temperature drop to a 61°F average high and adds 0.9 mph of peak wind, making September's window considerably more comfortable for scoring.
