August in Grand Rapids quietly earns a reputation as a premium summer golf month, but the precipitation record tells a different story. At 15 rain days, it ties May and June as the third-wettest month of the year — 15 of 31 days on average see some form of precipitation. What the numbers do deliver on is the heat and the calm: an 80°F average high (second-hottest of the year) and 9.9 mph peak winds, the lowest of any month on the calendar.
The 17°F daily swing — from a low of 63°F up to 80°F — is the other thing that catches people off guard. Morning tee times can feel genuinely cool, requiring an extra layer that you'll be stuffing in the bag by the back nine. Plan for that range and August in Grand Rapids rewards you with the softest winds of the year and temperatures that stay well within the ideal 60–80°F comfort band.
With 15 precipitation days spread across the month, morning tee times before noon give you the best odds of beating afternoon showers that build as the day heats toward the 80°F average high. Targeting a 7–9 AM start captures the coolest, calmest window of the day. See how conditions rate hour by hour on our playability scale.
August loses just two degrees off July's 82°F average high and sheds one precipitation day, making the months feel nearly identical on paper — but August's slightly calmer winds (9.9 mph vs. July's 10.1 mph) give it a modest edge for scoring conditions. September pulls things noticeably cooler at 75°F, drops three precipitation days to 12, and sees winds tick back up a hair to 10.2 mph, making it the drier but crisper option. If rain tolerance is your concern, September is the cleaner month; if warmth matters most, August holds the advantage.

Not typically. The average high sits at 80°F, which is right at the upper edge of the ideal comfort range, and morning rounds rarely push past that threshold. The bigger adjustment is the 17°F daily swing — early starters will find 63°F lows that feel more like early fall than peak summer.
With 15 precipitation days on average, there's roughly a coin-flip chance of encountering rain on any given day, making August one of the three wettest months of the year. That said, the peak wind stays at just 9.9 mph — the calmest of any month — so many showers pass quickly rather than arriving with a prolonged storm system. Checking a short-range hourly forecast the morning of your round is the most reliable way to time your tee time.
