The one variable that defines golf in Honolulu in August is precipitation — or the relative lack of it. With only 13 rainy days, August is the driest month of the year here, and that single fact shapes the entire experience. Afternoon tee times are less likely to be interrupted, fairways firm up, and the tradewind cooling that normally battles moisture feels more like an ally than a complication.
Temperatures sit at their annual peak — 85F highs and 74F lows — but the 11-degree daily swing means early-morning rounds start comfortably rather than oppressively. Wind remains a factor at 14.9 mph, which is technically the 3rd-windiest month of the year and will require club adjustments on exposed coastal holes. Come in expecting firm, fast conditions and occasional gusts rather than the wet, sluggish turf that defines Honolulu winters.
Book morning tee times before 9 AM to catch the calmest wind of the day — afternoon tradewinds regularly push into the 14-15 mph range, which is enough to turn a straight approach into a two-club decision. With August being the driest month, last-minute availability is tighter than the shoulder-season badge might suggest, so reserve at least a week out. See how conditions rate hour by hour on our playability scale.

If dry conditions are your priority, August is the window to take.

August is the driest month of the year in Honolulu, with only 13 precipitation days, which makes it the most reliably dry window for golf. Temperatures peak at 85F, and while the 14.9 mph tradewinds are the third-strongest of any month, they are lighter than July's 16.2 mph. Overall conditions favor August over most other months if avoiding rain is your main concern.
Peak winds in August average 14.9 mph, which falls in the moderate range and will meaningfully affect ball flight on open or elevated holes. Morning rounds generally see calmer conditions before the tradewinds build through the afternoon. Club up one to two clubs on into-the-wind holes, especially on courses with ocean or ridge exposure.
