August in Indianapolis comes down to one thing: rain. With 15 precipitation days, it ties for second-wettest month of the year, and that single variable shapes everything about how you plan a round. Morning tee times carry less risk than afternoons, when thunderstorms tend to build in the summer heat. Temperatures are comfortable enough — highs around 84F and lows near 65F — and the wind is actually the calmest it gets all year at 8.9 mph. So when the weather cooperates, conditions are genuinely good. The catch is that nearly half the days in the month have some form of precipitation, which means flexibility matters more than any other factor in August.
The 19-degree swing between the daily high and low is worth noting for packing purposes. Early mornings can feel pleasant, almost cool, before the heat and humidity build. If you can secure a 7 AM tee time and keep an eye on afternoon radar, August golf in Indianapolis is more manageable than the precipitation count alone suggests.
With 15 precipitation days and afternoon convective storms common in summer, book the earliest available tee time and treat anything after noon as a backup plan. Courses in the Indianapolis area fill early on low-rain-probability mornings, so locking in your slot 5-7 days out is worth the effort in August.

August is marginally drier than July, dropping one precipitation day (from 16 to 15) and slightly cooler by one degree on the high. The real improvement comes in September, which sheds four more precipitation days down to 11 and cools to a 78F average high — making it a noticeably easier month to plan around. Wind stays calm across all three months, so that is not a differentiating factor.

August averages 15 precipitation days, tying it for the second-wettest month of the year alongside January and April. That does not mean full-day washouts, but it does mean roughly one in every two days has some measurable precipitation. Building flexibility into your schedule — or booking morning rounds when storm risk is lower — is the practical way to handle it.
The average high of 84F is the second-hottest of the year, so heat and humidity are real considerations, especially mid-afternoon. The saving grace is that peak wind sits at just 8.9 mph, the calmest month of the year, which keeps conditions from feeling oppressive when temperatures are manageable. Hydration and an early tee time go a long way.
