First Introduction
Skywatchers are enthralled with the rare yet amazing natural phenomenon known as the aurora borealis, or Seattle Northern Lights. Because of its southern latitude and frequent cloud cover, Seattle is not the best place for consistent aurora sightings; yet, during times of great solar activity one can see this amazing light show.
This book addresses all you need to know about observing the Northern Lights in Seattle, including the ideal times, viewing sites, and advice for optimizing your chances of seeing this beautiful celestial occurrence.
What Generates the Northern Lights?
Charged particles from the sun mix with the Earth’s atmosphere to produce vivid displays of green, pink, purple, and blue lights known as the Northern Lights. These lights are most often seen close to the magnetic poles (such as in Alaska, Canada, and Norway), but during intense geomagnetic storms the auroras may be seen considerably further south—including Seattle, Washington.
Do the Northern Lights Show Up in Seattle?
Indeed, but only under appropriate circumstances. Though it is rare in Seattle, the aurora borealis is seen when solar activity is strong and the heavens are clear. Strong geomagnetic storms (Kp index of 6 or above) when the aurora oval stretches southward offer the best prospects.
Affective Elements Influencing Visibility:
- Solar Activity: Strong solar storms force the aurora farther south, where it is seen in cities like Seattle.
- Light Pollution: City lights can hide the aurora; so, it is advisable to visit darker regions.
- Weather: Cloudy or wet skies will obscure visibility.
- Time of Year: Longer, darker evenings provided by fall and winter months enhance viewing conditions.
Best Dates to View the Northern Lights in Seattle
Solar activity and weather variables determine when the Seattle Northern Lights would be most visible. You have the best possibilities right here:
1. Period of Peak Solar Activity
Northern Lights activity tracks an 11-year solar cycle. Around 2025, the next peak is projected, so auroral activity in the next years could rise.
2. Fall and Winter Months (September through March)
- Longer nights give aurora watchers additional darkness.
- Less cloud coverage enhances visibility.
3. Strong Geomagnetic Storms (Kp 6 or Higher)
- On a 0 to 9 scale, the Kp index gauges geomagnetic activity.
- A Kp of 6+ raises the possibility of auroras showing up in Seattle.
- Aurora forecasts are available on websites including NOAA’s Space Weather Prediction Center (SWPC).

Advice on Seeing and Filming the Northern Lights
1. Consult the Aurora Forecast
- Track activity using apps including NOAA’s Aurora Forecast, Space Weather Live, and Aurora Alerts.
- For Seattle visibility, look for a Kp index of 6+.
2. Choose a Dark, Elevated Spot
- Avoid city lights and seek higher altitudes for better viewing.
3. Get Ready for Cold Nights
- Dress warmly, particularly if you are heading to the mountains.
- For extended waits, pack blankets, hot drinks, and a comfortable chair.
4. Use a Manual-Setting Camera
- A DSLR or mirrorless camera with a tripod works best.
- Adjust to ISO 800-1600, f/2.8-f/4, and 10–20 second shutter speed for the best shots.
5. Be Late and Patient
- Auroras can be unpredictable and may appear for only a few minutes.
- The ideal sightings fall between 10 PM and 2 AM.
