August splits golfers in Kailua-Kona into two camps. For the traveling golfer flying in from the mainland, the conditions look appealing on paper: temperatures peak at 82°F, winds hold at a calm 7.4 mph, and the daily swing of just 9°F means you can dress the same at 7 AM as at noon. That combination makes for comfortable, predictable rounds. For the local regular, though, August is a familiar grind — 23 precipitation days over the month means moisture shows up almost every day in some form, typically as brief passing showers rather than prolonged rain. Courses stay playable, but afternoon humidity and wet fairways are routine.
The traveler chasing one good week will likely find it. The local who plays four or five times a month knows that fewer than half those rounds will feel truly dry underfoot. Season tier here is Variable, and that label earns its keep in August.
Tee times before 9 AM give you the best chance of finishing before afternoon convective showers build — with 23 precip days in the month, waiting until midday is a consistent gamble. Book early in the week too, since weekend slots at Hualalai and Mauna Lani fill fast even in a shoulder-humidity month like August. See how conditions rate hour by hour on our playability scale.

← July in Kailua-Kona, HI • September in Kailua-Kona, HI →
August logs 23 precipitation days, making it the 4th-wettest month of the year — tied with September. Most of that comes as short tropical showers rather than all-day rain, so rounds rarely get cancelled outright, but you should expect at least some wet conditions on the majority of days you play.
At an average high of 82°F, August is tied for the hottest month of the year in Kailua-Kona alongside September and October. That's within the comfortable playing range, but the combination of heat and high humidity means early tee times — before 9 AM — feel significantly better than midday rounds.
