Tonight in Reykjavík
Reykjavík sits at a geomagnetic latitude of 68.8° N, close to the auroral oval itself, so aurora is possible even on quiet nights (Kp 0–1) whenever the sky is dark and clear. Tonight's NOAA forecast peaks at Kp 3 (quiet) during the dark hours, which is enough for Reykjavík.
Open-Meteo expects about 79% cloud cover on average between 9 pm and 8 am local time, with no mostly clear hours.
The Moon is 100% illuminated (full moon), bright enough to wash out a faint aurora, so only a stronger display will stand out. For the best view look up: the oval is often overhead or even to the south, from somewhere away from street lights.
Right now NOAA's OVATION model gives up to 16% chance of aurora in the part of the sky visible from Reykjavík. OVATION is a short-range nowcast (30 to 90 minutes ahead), useful for deciding whether to step outside now.

3-day Kp forecast
3 of the next 3 days reach the Kp 0 that Reykjavík needs. Kp is a global 0–9 index of geomagnetic activity, issued in 3-hour blocks (UTC); NOAA forecasts beyond 24 hours are uncertain, because storms are triggered by solar eruptions that take 1–3 days to arrive.
| Day (UTC) | Max Kp | Level | Enough for Reykjavík? |
|---|---|---|---|
| 2026-10-25 | 2 | quiet | Yes |
| 2026-10-26 | 3 | quiet | Yes |
| 2026-10-27 | 1.7 | quiet | Yes |
Why Reykjavík sees aurora on quiet nights
The aurora forms in an oval around the geomagnetic pole, which sits in the Canadian Arctic (about 80.8° N, 72.8° W), not at the geographic pole. That is why the Kp a city needs depends on its geomagnetic rather than its geographic latitude. At Kp 0 the oval's edge is near 66° geomagnetic; each step of Kp pushes it roughly 2° toward the equator.
At 68.8° geomagnetic, Reykjavík lies under the usual position of the auroral oval: on quiet nights the aurora is often overhead, and during strong storms (Kp 5+) the oval can move equatorward past the city, so the display may then be to the south.
