In St. Louis, July's tee-sheet strategy comes down to one question: how early can you get out? With an average high of 88°F — the hottest month of the year — and a low of 71°F, the daily temperature swing is only 17°F, which means the early morning window closes faster than you'd expect. By 10 AM the heat is already building toward uncomfortable territory, and humidity amplifies every degree.
The other pressure on your booking is rain. July is the second-wettest month of the year at 17 precipitation days, meaning better-than-even odds of an afternoon storm on any given week. The silver lining: winds average just 9 mph peak, the second-calmest reading of the year, so when you do get a clean morning slot, conditions can feel surprisingly manageable. The 'Variable' season badge is accurate — the range between a 6 AM calm round and a 2 PM washout is as wide as it gets all year.
With 17 potential rain days and highs hitting 88°F, prioritize tee times between 6 AM and 8 AM — afternoon slots carry a high risk of both heat and storm delays. Book as early in the week as possible, since popular morning slots tend to disappear well before the weekend. See how conditions rate hour by hour on our playability scale.
July is 2°F hotter than June and adds four more precipitation days (17 vs. 13), making it a meaningfully tougher month to schedule around despite June's slightly windier average of 10.2 mph. Moving into August, the high drops to 85°F and precip days fall by one to 16, so August offers a modest but real improvement in both heat and storm frequency. July sits at the uncomfortable peak of both metrics, sandwiched between a wetter-than-expected June and a slightly cooler August.

It depends entirely on your tee time. The average high of 88°F is the hottest of any month in St. Louis, and the low only dips to 71°F, so the cooling window is short. A 6–7 AM start is playable for most golfers; anything past 11 AM risks genuine heat stress, especially with Missouri humidity factored in.
July logs 17 precipitation days, making it the second-wettest month of the year. That doesn't mean 17 full-day washouts, but it does mean afternoon convective storms are common enough that mid-day and afternoon rounds carry real interruption risk. Building in flexibility — or booking early-morning rounds — is the practical way to handle the month.
