Seattle woke up to crisp, clear skies Monday, with Boeing Field starting the day around 46°F. Sunshine sticks around through the afternoon, setting up a classic spring split personality: inland neighborhoods warm nicely into the upper 60s to near 70°F, while the waterfront and coastal spots stay stuck in the mid 50s. A marine push tonight will flip the switch to breezier, gustier conditions along the coast as we head into Tuesday.
Afternoon Temperatures
Most of the city is in for a pleasant, mostly sunny day, with a high near 69°F and light southwest winds that will feel more like a gentle nudge than a shove. Interior valleys and areas away from the water could sneak into the lower 70s, while coastlines stay cooler under persistent onshore flow that keeps that marine chill in play.
Overnight, temperatures drop back into the low 40s across much of the area. Looking a bit farther ahead, some of the colder inland pockets could flirt with freezing later this week, so gardeners may want to keep an eye on those more delicate plants.
Winds And Marine Advisories
The National Weather Service has a Gale Warning up for the central and eastern Strait of Juan de Fuca from 11 a.m. Monday, April 6, through 5 a.m. Tuesday, April 7. Several coastal zones and Admiralty Inlet are under Small Craft Advisories as seas build to around 9 to 11 feet, with up to 15 feet possible offshore, and winds that could gust roughly 30 to 45 mph.
Boaters should expect steep, choppy seas and higher waves tonight and into early Tuesday morning. Shoreline residents in more exposed locations may hear or feel those stronger gusts as the marine push rolls through. For official timing and zone specifics, check NWS Seattle and our April 5 update.
What To Watch
Small craft operators should seriously consider staying tied up until conditions settle down. Rough seas and higher gusts are the main issues on the water, and they will make life uncomfortable and potentially hazardous for smaller boats.
Across the city, commuters are not expected to see widespread impacts, but it is worth allowing extra time if your route hugs an exposed shoreline. Ferry riders should keep an eye on alerts in case the gusty winds stir up delays. If you are planning to head out on the water, make a point to check the latest forecast and marine statements before leaving the dock.
Looking Ahead
By midweek, a dry northwesterly flow settles in, keeping skies mostly dry with daytime highs in the upper 50s to low 60s and chilly nights in the 30s and low 40s. A cool upper level low may slide closer over the weekend, bringing a chance of light rain and cooler, cloudier conditions Saturday and Sunday.
On the bright side, no river flooding is expected over the next seven days, so while the breeze may kick up and the clouds may return, the region is not looking at any major high-water trouble in the short term.
