Seattle is waking up to a gray start, with low 50s across the city and Boeing Field near 54°F, but the script flips by afternoon. Skies should turn mostly sunny with highs near 71°F, making this the warmest day of the long weekend. Enjoy it while it lasts, because a stronger system is queued up for Memorial Day. On Monday, May 25, 2026, rain is expected after midmorning along with a noticeable uptick in southerly winds along the coast and inland waterways.
Afternoon Clearing And The Warm Spot
The low cloud deck is forecast to retreat back toward the coast by late morning, opening the door for inland neighborhoods to climb into the upper 60s and low 70s while waterfront spots run a few degrees cooler. South winds will stay on the mild side this afternoon, generally around 3-5 mph, and conditions are expected to remain dry through Sunday evening. Layer up for the usual cool morning start and a potentially breezy finish after sunset.
Memorial Day Rain And Gusty Winds
Rain is likely to arrive Monday morning and become steadier after about 8 a.m. on Monday, May 25, 2026, with highs near 62°F and showers hanging around through the day. Southerly winds will pick up Monday, generally around 8-13 mph, with gusts up to about 23 mph in more exposed coastal and sound-side areas. Forecasters are also flagging a slight chance of thunderstorms in parts of western Washington. For the latest watches and marine updates, see the National Weather Service.
Boaters, Ferry Riders And Park Events
Mariners should plan on building seas and strengthening winds. Forecasts show seas increasing from about 6-8 feet to around 12-16 feet by late Monday, and the National Weather Service has issued Gale Watches and Small Craft Advisories for portions of the coastal and northern inland waters. Secure loose gear, be ready for choppier-than-usual ferry rides, and pad your Monday travel schedule in case conditions slow things down. This update follows our earlier Memorial Day preview; see our prior Hoodline post on Seattle’s one golden day of sun for background.
Looking Ahead
Showery, unsettled weather is expected to linger into Tuesday, May 26, 2026, with a continued chance of rain and isolated storms before drier and warmer conditions return by midweek. Highs should rebound into the upper 60s and low 70s by Thursday as high pressure rebuilds, although long-period swells later in the week could again increase coastal hazards. Check updated forecasts before outdoor events or boat trips, since the timing and intensity of the incoming front could still shift.
