Overview

What to check before an outdoor plan in Seattle over the next few days. City forecast and air quality first, then the two mountain corridors most Seattle trips actually depend on.

The city itself rarely has a hard stop: it drizzles, and you go anyway. The two things that genuinely change plans here are wildfire smoke in late summer, which can push air quality into unhealthy territory for days at a time, and pass conditions in winter, when I-90 can require chains or close outright.

Weather & Air

Near-term forecast and air quality for the city itself. Use this for park, beach, and city-trail plans over the next couple of days. Marine air means mornings are often cooler and greyer than the afternoon, so a grey 9am says very little about 2pm.

Fire Restrictions

Seattle itself has no campfire restrictions to track, and beach fires at Golden Gardens follow city park rules rather than a burn ban. What matters here is DNR-protected land, which covers most of the day-trip country between the city and the Cascades. Check it before any plan involving a fire outside the city.

Mountain Access

The real reason to check conditions from Seattle. North Bend is about 35 minutes out and Snoqualmie Pass about 45, and the two together cover most day trips from the city. Snow, smoke, and pass closures show up here well before they show up downtown.

For winter driving, check WSDOT Snoqualmie Pass conditions for chain requirements and closures. Neither forecast above reflects road status.
