The defining variable for golf in Seattle in August isn't temperature or wind — it's the near-absence of rain. With only 8 precipitation days, August ranks as the second-driest month of the year, and the difference is felt on every round. Fairways firm up, greens hold their shape, and you rarely need to factor a mid-round downpour into your planning. Temperatures peak around 76°F in the afternoon and settle to 59°F by morning, putting the bulk of the day squarely inside the ideal 60–80°F range.
Peak wind averages 11.2 mph, qualifying as moderate by site standards but sitting at the second-calmest reading of the year. Early tee times in particular tend to be still, with the light breeze arriving later in the afternoon. The 17°F daily swing means a light layer at the first tee is worth carrying even when the afternoon looks warm on your phone.
August is Seattle's second-driest month and demand reflects it — book weekend tee times at least 10–14 days out, as the most sought-after municipal and public courses fill quickly once the dry forecast is confirmed. Midweek morning slots open up more reliably and also catch the calmest wind before afternoon gusts develop. See how conditions rate hour by hour on our playability scale.
July is marginally warmer at 77°F high versus August's 76°F, and meaningfully drier with just 5 precipitation days compared to August's 8 — so if you're splitting hairs, July edges August on pure conditions. That said, August still holds a clear advantage over September, which drops to a 70°F high and climbs to 11 precipitation days while matching August's 11.2 mph peak wind exactly. August sits in the middle of Seattle's dry window, closer to July's quality than to September's slide toward fall.
