Northern Lights Forecast for Oregon

Oregon aurora planning thresholds range from Kp 7.0–9.0; darkness and local cloud cover still determine whether aurora is visible.

Best Viewing Season in Oregon

In a typical year no location we track in Oregon records a single clear night with Kp at its threshold. Only an extreme geomagnetic storm brings aurora this far south. Kp last reached the local threshold on 2026-01-21. Figures below are for Portland, the best-placed of the 4 locations we track in Oregon. They describe a typical year built from the 1996-2026 planetary Kp record and the 2001-2020 cloud normal — not a forecast. Each city page shows tonight's live cloud, moon and darkness instead.

That oval line is a model estimate of where the aurora sits at extreme Kp, not a measurement — the threshold date above comes from the Kp record itself.

Frequently Asked Questions

Can you see the northern lights in Oregon?

No — not in a typical year. Oregon averages under one clear night with the aurora in reach, and the planetary index has to reach Kp 7+ for it to be visible at all, which last happened on 2026-01-21. Only an extreme geomagnetic storm brings the aurora this far south, so this is a watch-the-alerts situation rather than a month to plan around.

Where are the darkest skies in Oregon?

Check our city pages for specific dark sky recommendations near each location.
