December in Seattle is the coldest month of the year, with an average high of just 46 era°F and 22 precipitation days — the second-wettest and second-windiest month on the calendar. Rounds are short on daylight, genuinely cold, and interrupted by rain more often than not. The season-tier badge says it plainly: this is cool/cold season golf.
For the traveling golfer, December is a hard sell. You're booking a trip around a month that averages 22 wet days and a peak wind of 13.4 mph — conditions that are difficult to plan around. The local regular, however, often finds a rhythm here. Familiar courses mean quick decisions when a window opens, and gear is already dialed in for the damp, heavy turf. If you know Seattle golf in December, you know to treat a dry 46°F morning as an opportunity, not a compromise.
Book an early-morning tee time mid-week and treat it as tentative — with 22 precip days in the month, having a same-day cancel policy or a course that offers rain checks is worth prioritizing over convenience of location. Morning windows between fronts are real but brief, so checking a short-range hourly forecast the evening before is more useful than a week-out booking decision.

November runs 4°F warmer — a 50°F average high versus December's 46°F — with two fewer precipitation days and nearly identical peak wind at 13.5 mph vs. 13.4 mph, making November the marginally better month to play. Looking ahead, January is almost a mirror image of December: one more precip day, one degree higher average high, and a nearly identical peak wind of 13.3 mph, so conditions don't meaningfully improve as you cross into the new year.

Yes, but it takes flexibility. With 22 precipitation days in December, the odds of a completely dry round are low, but breaks between fronts do occur — often in the morning. Courses in the area stay open through winter, so availability isn't the obstacle; weather windows are.
The average low is 38°F and the average high only reaches 46°F, so you're looking at a tight 8-degree daily swing — meaning it stays cold all day rather than warming up meaningfully by afternoon. Wind averaging 13.4 mph at peak makes the effective playing temperature feel noticeably colder than the thermometer reads.
