Seattle August Weather Outlook: Rain, Smoke, and Sunshine

Why this matters: Understanding these weather patterns helps residents prepare for varying conditions, from potential thunderstorms to smoky air and rising temperatures. Staying informed allows for better planning of outdoor activities and necessary precautions for health and safety.

The Seattle area is experiencing a mixed bag of weather conditions in August 2025. The month started with a hint of rain, a welcome change after a notably dry July, but the rainfall has not been significant enough to offset the overall deficit. According to the National Weather Service, the region is 6.5 inches below its normal rainfall since January 1 and 9 inches below average for the water year, which began on October 1. This follows a June that was the third-driest in the past 130 years for the state of Washington.

Adding to the complexity, smoke from wildfires, particularly the Bear Gulch Fire in the Olympics, is affecting air quality in western Washington. Residents are advised to monitor air quality reports and take necessary precautions.

Looking ahead, the forecast indicates fluctuating temperatures with a chance of thunderstorms mid-week, followed by a return to sunshine and warmer temperatures heading into the weekend. High pressure is expected to build, potentially pushing temperatures into the low 90s early the following week.

Actionable Takeaways: Stay updated on weather forecasts and air quality reports. Consider limiting outdoor activities during periods of heavy smoke or high temperatures. Conserve water to mitigate the impact of the ongoing rainfall deficit.

While some showers are expected, significant rainfall is unlikely to offset the current deficit.

Monitor air quality reports, limit outdoor activities, and use air purifiers if possible.

The forecast indicates fluctuating temperatures, with periods of sunshine and warmer conditions interspersed with cooler days.
