Wind is the defining variable for golf in Sioux Falls in July, and for once it works in your favor. July is the calmest month of the year here, with peak winds averaging just 11.9 mph — a meaningful drop from June's 14.1 mph. That extra stillness, combined with an 84°F average high (the hottest month of the year), means you're dealing with predictable ball flight on the warmest days of the calendar.
The tradeoff is precipitation. July lands as the 4th-wettest month of the year at 10 rainy days, so morning storm cells are a real scheduling factor. The daily temperature swing of 19°F — lows around 65°F, highs reaching 84°F — rewards early tee times both for comfort and for beating afternoon convective weather. Carry extra towels and watch radar closely; the rounds that start by 7 AM tend to finish clean.
With afternoon thunderstorms common across 10 precipitation days, booking the earliest available tee time — ideally before 8 AM — gives you the best chance of completing a full round before storm cells build. Midweek morning slots tend to open up more than weekends in July, so if your schedule allows flexibility, that's where to look first. See how conditions rate hour by hour on our playability scale.
July is essentially the calm eye between two windier months: peak gusts drop 2.2 mph from June's 14.1 mph down to 11.9 mph, then climb back 1.1 mph into August's 13.0 mph, making July the quietest stretch of the summer for shot-making. Temperature barely moves — just ±1°F against either neighbor — so heat isn't what separates July from June or August. Precipitation does shift slightly, with July losing one rainy day compared to June (10 vs. 11) but gaining one back heading into August (11 days).
