Sioux Falls compresses its golf into May through September, but those months deliver long days and surprisingly good scoring weather. June and September hit the sweet spot before and after peak heat. Prairie wind is the constant — 10 to 15 mph afternoons are standard issue.
Every club in your bag will fly a different distance at some point during a Sioux Falls round, and the prairie topography is why. With essentially no terrain to break the wind, exposed layouts here see double-digit peak winds every single month of the year — from a relative lull of 11.9 mph in July up to 17.2 mph in April. Club selection isn't optional strategy here; it's survival. A 150-yard carry into a 15-mph headwind on a flat South Dakota layout can easily become a 6-iron decision instead of a 9-iron.
The good news is that Sioux Falls temperatures cooperate from late May through September, pushing highs into the 70s and 80s. June through September strings together 11 or fewer precip days per month, so the calendar is workable. The catch is that even on a sun-drenched July afternoon, you're still managing wind. Locals read it instinctively; visitors burn strokes learning it the hard way.
April is the windiest month of the year at 17.2 mph average peak, and it pairs that with 13 precip days and average lows of 36°F — a rough combination for a comfortable round. May warms to a 70°F high but tops the calendar with 14 precip days, making it the wettest month. Tee times in early morning before afternoon gusts develop are worth the extra planning.
July is as calm as Sioux Falls gets, with average peak winds of 11.9 mph — the only month that approaches the site's ideal threshold. Highs reach 84°F, which pushes past the comfortable 60–80°F window, but early rounds stay manageable. June averages 14.1 mph and August 13.0 mph, so even summer rounds require you to account for breeze on approach shots.
September drops average highs to 77°F, right in the comfortable range, while precip days fall to just 8 — tied with October for the fewest among playable months. Wind eases to 13.8 mph, lower than any spring month. October is still playable at 61°F average high with only 8 precip days, but average lows of 43°F mean morning rounds require layers.
December through February highs stay between 26°F and 34°F, well outside any reasonable golf window. January's average low hits 12°F, the coldest of the year. Wind doesn't take a winter break either — December through February all average between 14.4 and 15.5 mph peak winds, so there's no calm consolation prize for the brave.
June, July, and September combine the warmest temperatures with the lowest wind averages on the calendar. July's 11.9 mph peak wind is the calmest Sioux Falls gets all year, while September pairs a comfortable 77°F average high with only 8 precip days — tied with October for the fewest in the golf season. June offers similar conditions — 83°F highs, 11 precip days, and 14.1 mph winds — making it the best window before peak summer heat and humidity stack up.
July is the calmest month, averaging 11.9 mph peak wind — the only month that gets close to genuinely light conditions. Every other month averages 13 mph or higher. If wind-sensitive shot-making is a concern, July morning rounds offer the best odds of calmer air.
Both are strong options, but they favor different preferences. June offers an 83°F average high and 14.1 mph winds, while September drops to 77°F with 13.8 mph winds and only 8 precip days — tied with October for the fewest in the golf season. September's lower precipitation risk gives it a slight edge for trip planning, though June's longer daylight hours allow more scheduling flexibility.
October is possible but requires timing. Average highs reach 61°F, which sits right at the lower end of comfortable scoring weather, and only 8 precip days keep the courses relatively dry. The challenge is morning lows averaging 43°F and winds returning to 14.7 mph — plan for midday tee times once temperatures climb and accept that you'll be adding a club into the wind on most approach shots.
