Seattle is waking up under a blanket of low clouds and cool air this morning, with Boeing Field (KBFI) reporting about 61°F and south‑southwest winds around 7 mph. The marine layer should thin by late morning, giving way to mostly sunny skies and a high near 74°F this afternoon. With light winds and only a slim chance of rain, most outdoor plans should be in the clear today.
Afternoon Sun, Mild Tonight
Skies are expected to clear into the afternoon, with highs topping out near 74°F and south‑southwest breezes of 3–7 mph. Tonight stays on the comfortable side, with partly cloudy skies and a low around 57–58°F as winds ease back to 1–6 mph. Forecasters are not expecting any measurable rain overnight.
Weekend And Next Week Warm Up
Temperatures climb through the weekend, with Saturday near 75°F and Sunday around 77°F. A sharper warmup moves in early next week, pushing highs to around 83°F on Monday and close to 86°F on Tuesday. The National Weather Service reports that a building ridge will lift temperatures well above seasonal averages and raise the region's HeatRisk to Moderate across the lowlands next week. Forecasters also flag the potential for isolated pockets of higher heat risk Tuesday and Wednesday if readings run a bit hotter than currently expected.
Who Should Take Precautions
Those most vulnerable to heat, including older adults, young children, outdoor workers and anyone without reliable air conditioning, should plan ahead for the hotter stretch and seek cool indoor spaces during the warmest part of the afternoon. For details on cooling centers and practical heat‑safety steps, see King County Public Health. Hydrate regularly, ease up on strenuous outdoor work from mid‑afternoon into early evening, and check in on neighbors who might need a hand.
Commute And Boating Notes
Morning low clouds near the waterfront could bring briefly reduced visibility for early commuters, but conditions should improve by mid‑day for most neighborhoods. Mariners should keep an eye out for stronger afternoon sea breezes later in the week as diurnal pressure patterns strengthen and check the marine forecast before heading out. If you are planning evening activities outside, Sunday into midweek will be the warmest stretch, so bring water and opt for shade or air‑conditioned spots when possible.
