May splits the difference for golfers in Seattle: the worst of winter's grey is behind you, but the reliable dry windows of summer haven't fully arrived yet. Highs reach 63°F with lows around 48°F, giving you a 15-degree daily swing that means a 48°F start can climb toward 63°F by mid-afternoon. With 16 precipitation days across the month, 16 of 31 days in May see some precipitation — rain is still a regular visitor.
That distinction matters when thinking about who May actually suits. A local regular knows to track the forecast daily, grab the dry Tuesday when it appears, and stay flexible. A traveling golfer booking a week in advance takes on real variance: you might land three clean rounds, or you might peel layers all day. May rewards familiarity with Seattle's micro-weather patterns more than it rewards a fixed itinerary.
Book morning slots only if you have same-week flexibility to swap days — the 16-day precipitation spread means early commitments often collide with rain. Afternoon tee times starting around 1 PM can pay off when marine layer burns off by midday, which happens regularly in May but rarely on a predictable schedule. See how conditions rate hour by hour on our playability scale.
May improves meaningfully on April, gaining 7°F in average high while shedding one precipitation day and dropping peak wind from 12.8 mph down to 12 mph — small margins, but the warmer temperatures make a real difference in comfort. June is the cleaner step forward, cutting precipitation days by three more and adding another 6°F, which pushes conditions closer to Seattle's short reliable window. If your schedule has any flexibility, June edges May on nearly every measure.
Climate normals show the long-term picture, but day-to-day weather varies. Check today's live golf weather score for Seattle, WA for the current playability rating, hourly wind, temperature, and the recommended tee time window.

It can be, but it carries more weather risk than most destination months. With 16 precipitation days and a high of only 63°F, you're likely to encounter at least some rain during a multi-day visit, and temperatures stay cool enough that morning rounds require real cold-weather gear. Travelers who build in schedule flexibility and treat dry windows as bonuses tend to come away happiest.
May is actually tied for the 5th-driest month of the year in Seattle at 16 precipitation days, which offers useful context — the city's wettest months are considerably worse. That said, 16 days still means rain appears on more than half the calendar, so 'drier than winter' shouldn't be mistaken for 'reliably dry.'
