Seattle rolled out of bed under a blanket of gray on Saturday, July 11, 2026, with Boeing Field (KBFI) logging cloudy skies and a cool 61°F. The familiar marine layer is expected to hang around through the morning, then thin into partly sunny skies by afternoon as highs climb to about 73°F across most inland neighborhoods.
Today looks mostly cloudy to partly sunny, with a high near 73°F and a cooler low around 57°F overnight. Sunday, July 12, 2026, is on track to be mostly sunny with a high near 71°F before a stronger warming trend kicks in early next week. It is the same gray-mornings, sunny-afternoons setup we have been riding for days, as outlined in our earlier look at the marine layer putting summer on hold.
Afternoon Winds And Boaters
Choppy conditions are possible offshore and across the Strait of Juan de Fuca, with watches and Small Craft Advisories in effect for portions of the local waters into tonight and again this evening. Boaters should wear life jackets and be ready for rougher seas, and it is smart to check the latest marine forecast from the National Weather Service before casting off.
Mornings, Commutes And Flights
Low clouds and mid-level stratus could keep the pre-dawn commute cooler and a bit damp, with occasional reduced visibility on surface streets and for early flights. Conditions should lift to sunnier skies by mid to late morning, so mid-day outdoor plans and afternoon events will be comfortable, helped along by light southwest breezes.
Next Week Quick Warm-Up
High pressure rebuilds early next week, bringing a warm trend Monday, July 13, 2026, and Tuesday, July 14, 2026. Highs should reach near 76°F on Monday and climb into the low 80s inland on Tuesday. Forecasters note a modest chance for elevated heat impacts in parts of the Seattle metro Monday through Tuesday, so it is worth planning ahead for extra water, shade and breaks if you will be outside for long stretches.
Bottom line: keep a jacket handy for the cool gray mornings, then enjoy the sunnier, warmer afternoons. If you are heading out on the water or catching an early flight, a quick check of marine and flight updates before you go could save you some headaches.
