Seeing the Aurora in Seattle
Located in the Washington region of United States, Seattle is a notable destination for night sky watchers. Situated far south at 47.6°, the auroral oval rarely reaches this area. While it takes patience and luck, catching a display from here is an unforgettable experience.
FAQ
What Kp index do I need to see the northern lights in Seattle?
In Seattle, you usually need at least Kp 7 to have a reasonable chance of seeing the northern lights. Lower Kp can still bring a faint aurora display low on the northern horizon, but it is less common.
This is based on magnetic latitude, and Kp index is a global geomagnetic index, so treat it as a rule of thumb, not a location-specific guarantee.
Tonight, the NOAA Kp index forecast is 2.6 to 3.4. That is below the usual Kp index threshold for Seattle, so seeing the aurora is unlikely.
