Seattle rolled into Saturday under a cool, partly cloudy sky, with temperatures hovering around 48°F at Boeing Field and a light easterly breeze in the mix. Those clouds should thin through midmorning, setting up a mostly sunny afternoon and a comfortable high near 63°F for most neighborhoods.
The commute looks straightforward and dry, with mild conditions, light west-northwest winds around 2 to 6 mph, and only a stray shower possible early this morning. Overnight lows dip back into the upper 40s. Sunday turns sunnier, with highs climbing into the mid-60s, while spots along the shoreline near Elliott Bay stay a few degrees cooler.
Warm-Up Next Week
According to the National Weather Service, the region flips the switch starting Monday, with highs jumping into the mid to upper 70s and a peak near 81°F on Tuesday. The agency is flagging a Moderate (orange) HeatRisk for much of western Washington away from the immediate waters, and the warmest pockets in the South Sound could push close to 90°F. Daytime humidity is expected to fall into the mid-20s, which means outdoor work and long stretches in the sun could go from pleasant to punishing pretty quickly.
How To Prepare
Plan ahead for Tuesday afternoon especially: ease up on strenuous outdoor activity during the hottest hours, keep water handy, and scout out local cooling options if you do not have air conditioning. The city offers heat-safety guidance and a list of cooling spaces on its heat safety page; see the City of Seattle for resources. Check in on older adults, young children, and pets, and do not leave anyone in a parked car on warm afternoons.
Boaters And Waterfront
Out on the water, expect breezy onshore winds and choppy seas. Advisories are up for some central waters through late tonight, and seas could build to roughly 7 to 9 feet into Sunday night. If you are catching a ferry or heading onto Puget Sound this weekend, give yourself extra time and make sure gear is secured before things get bumpy.
