Seattle woke up under a stubborn marine layer Friday, with Boeing Field clocking overcast skies and a cool 61°F to start July 3. Waterfront neighborhoods can expect gray, misty vibes through the early hours, but the low clouds should gradually give way to sunshine by afternoon. Inland spots are on track for highs in the low to mid 70s, while areas hugging the shoreline stay a few degrees cooler.
Morning Clouds And Afternoon Clearing
The shallow marine layer will keep much of the city socked in with clouds through Friday morning before the sun finally chews through the deck later in the day. Highs are expected to land in the low to mid 70s away from the water, with shoreline neighborhoods topping out in the mid 60s. Overnight lows will sit mostly in the mid ranges, keeping evenings comfortable for those early holiday plans. The overall pattern trends sunnier through the Fourth of July weekend, with only modest warming, according to the National Weather Service.
Small Craft Advisory Tonight For The Strait
A Small Craft Advisory is in effect from 5 p.m. Friday to 5 a.m. Saturday for central U.S. waters in the Strait of Juan de Fuca, so boaters are urged to steer clear of exposed waters or duck into sheltered harbors. Seas are expected to hold around 5 feet or less through Saturday before building to about 8 feet by Sunday, and westerly winds may push toward advisory strength, roughly 20 to 25 mph, on Saturday. Mariners should check the latest marine forecast and advisories before heading out, per the National Weather Service.
Plan Ahead
Layer up for those cool, gray mornings and plan your barbecues, park hangs, and rooftop fireworks viewing for the sunnier afternoons. If you are eyeing a waterfront outing tonight or at any point over the holiday weekend, consider moving it earlier in the day or launching from a more sheltered spot, and keep an eye on changing marine conditions. For most neighborhoods, the weather should stay mild and manageable, with only minor impacts on outdoor Fourth of July plans.
