January's numbers land hard on a Portland scorecard. With an average high of 47°F and a low of 36°F, you're looking at cold, stiff hands from the first tee — expect to lose a club or more of distance on full shots, and add strokes wherever feel and touch matter most. Rain falls on 23 days this month, tied with December for the most of any month in the year, which means cart paths are often the only safe route, fairways play soft and slow, and plugged lies in greenside rough are a genuine hazard rather than a rarity.
Peak winds average 13.1 mph — the highest of any month Portland sees — and while that's not a gale, it's enough to affect club selection on exposed holes at courses like Heron Lakes or Eastmoreland. The 11°F daily swing matters too: a 7 AM tee time means playing in near-freezing air, while a late-morning start recovers only a few degrees. January here is playable, but the conditions actively cost you shots. Plan for it.
Book late-morning slots — 10 AM or later — to let temperatures climb as close to 47°F as possible and to benefit from any morning fog or frost burn-off. January's 23 rain days mean same-week cancellations are common, so check cancellation policies and keep a backup date; gaps between fronts do open but they're short. See how conditions rate hour by hour on our playability scale.
January and December are nearly identical on paper — same 23 precipitation days, an essentially flat temperature difference of just 1°F, and winds within 0.2 mph of each other — so switching months won't change the experience meaningfully. The real improvement comes in February, which drops to 19 rain days and sees peak wind ease to 11.4 mph, making it noticeably drier and calmer. If your schedule has any flexibility, February returns better odds of a round that doesn't require toweling off the grip every other hole.

Most public courses in Portland remain open in January, though cart restrictions and temporary greens are common given the 23 average rain days. Courses like Heron Lakes and Eastmoreland typically stay accessible but conditions depend heavily on drainage after back-to-back wet days. Calling ahead or checking course websites the day before is worth the two minutes.
Morning temperatures regularly sit near the 36°F average low, so early tee times can feel genuinely cold and frost delays are possible on exposed courses. By midday the average high reaches only 47°F, which limits how much the air warms up across the round. Layering for a starting temperature in the upper 30s and expecting to finish around 45°F is a realistic plan.
