Northern Lights in Honolulu Tonight
Live forecast for Honolulu, Hawaii: real-time solar wind measured 930,000 miles upstream, NOAA's OVATION model, your cloud forecast, and tonight's darkness, with one verdict for your eyes and one for your phone camera.
Aurora is unlikely tonight (0%), for eyes and cameras alike (0%). Kp is 3.7 right now, and Honolulu needs Kp 9.5+ for eyes and Kp 9.5+ for a phone camera. The best window is 4 AM–6 AM with 2% clouds and a forecast Kp up to 2.3.
Tonight's aurora odds
Your chance of catching aurora at any point tonight, combining the Kp forecast for tonight's dark hours, the cloud forecast, and the moon.
How we get this: forecast Kp peaks at 2.3 tonight, a 0% chance of reaching your eye threshold (Kp 9.5+) and 0% for camera (Kp 9.5+), times a 96% chance of usable sky in your clearest dark hours.

Aurora viewing in Honolulu: what it takes
Honolulu sits at magnetic latitude 21.8°, the number that actually decides your aurora odds (it differs from geographic latitude because Earth's magnetic pole sits over the Canadian Arctic, which is why the Midwest outperforms Europe at the same map latitude). From here, aurora appears low on the northern horizon at roughly Kp 9.5, fills the northern sky around Kp 9, and can pass overhead at Kp 9.5+. Eye-visible displays happen only during rare extreme (G5) superstorms.
The threshold most sites won't tell you: your phone camera only needs about Kp 9.5. A 3-second night-mode exposure collects light your dark-adapted eyes cannot, so on many nights the honest answer is "no to your eyes, yes to your camera." That's why this page gives two verdicts.
Where to watch near Honolulu

- Mauna Kea Visitor Station ↗ (189 mi), Bortle 1. 9,200 ft on the world's premier astronomy mountain.
- Death Valley National Park ↗ (2656 mi), Bortle 1, International Dark Sky Park. The largest Dark Sky Park in the US, with Gold Tier skies.
- No time for a drive? Any spot with a dark, unobstructed northern horizon (a lakeshore, a ridge, farmland north of the city) beats a bright parking lot by a full activity level.
Northern lights in Honolulu: FAQ
›Can you see the northern lights in Honolulu tonight?
It depends on tonight's geomagnetic activity: Honolulu sits at magnetic latitude 21.8°, so aurora becomes visible on the northern horizon at roughly Kp 9.5+ and can appear overhead at Kp 9.5+. The live forecast at the top of this page combines the real-time solar wind, NOAA's OVATION model, tonight's cloud cover, and darkness to give you a straight yes/no answer, updated every couple of minutes.
›What Kp index does Honolulu need for aurora?
About Kp 9.5 for a visible glow on the northern horizon, Kp 9.5+ for overhead displays, and only about Kp 9.5 for a phone camera on night mode to capture it. Camera thresholds are lower because long exposures pick up sub-visual light your eyes can't.
›How often can you see the northern lights in Honolulu?
At magnetic latitude 21.8°, Honolulu sees eye-visible aurora only during rare extreme (G5) superstorms. We're near solar maximum of Solar Cycle 25, so activity through 2026–2027 runs well above average.
›Where should I go to watch aurora near Honolulu?
Get away from city light and find an unobstructed view to the north. The best nearby dark-sky options are Haleakala National Park (117 mi), Mauna Kea Visitor Station (189 mi), Death Valley National Park (2656 mi). Even a rural road 20–30 minutes north of town dramatically improves what you'll see.
›What's the best time of night to see aurora in Honolulu?
Statistically 10 PM to 2 AM local time, when your location rotates under the strongest part of the auroral oval, though substorms can fire at any dark hour. Our best-window forecast above combines darkness, clouds, and predicted Kp for tonight specifically.
