Northern Lights Forecast Tonight — Live Kp & Odds for 70 Places

Is it out tonight?

A calm night. This Kp means a faint glow only at the highest latitudes — Svalbard, north Greenland. Below 66°N the sky most likely stays empty tonight.

An ordinary night — light pollution will decide it.I'm staying in a big northern city (Tromsø, Alta, Reykjavík). I can faintly see the lights from my window. What should I do to see them better?

Most northern European cities use low lighting, including street lamps; this reduces light pollution and lets the northern lights be seen even from within the city. Still, for the best experience go to a dark area away from the city lights. If that's not possible, at least move to a spot where you leave the bright lights behind you. The human eye is sensitive to bright light and takes time to adapt to the dark.

One push whenever NOAA forecasts a G1+ geomagnetic storm within 48 hours — wherever you are. On a big night the aurora reaches far south of its usual latitudes.

Whether you'll see it depends on geomagnetic latitude, not map latitude — which is why Yellowknife sees the aurora as readily as Tromsø, and Ushuaia needs a major storm. Both hemispheres, live against tonight's Kp.

Thresholds are averages. Real visibility also needs dark, clear skies and a cooperative moon — read every status as a chance, never a guarantee. High-latitude northern sites get no true darkness in their summer (≈ May–Aug), so a green “possible” there still means waiting for darker months. The Horizon / Overhead toggle is why sources disagree on a place's “Kp.”
