Northern lights in Romania tonight
Aurora borealis over the Carpathian Mountains, Romania - Retezat National Park, Bortle Class 1-2, elevation 1,500–2,500 m, Kp 7 threshold.
How the sky looks right now
Live Kp index from NASA & NOAA, mapped to what it means across Romania.
Aurora activity detected. Kp6 storm in progress. Good viewing conditions at high latitudes tonight.
How far south the glow reaches
At Kp 6, the auroral oval pushes down to ~54°N - covering every Romania town below.
7-day outlook for Romania
Predicted peak Kp each night, from NOAA's 3-day forecast and the 27-day solar-recurrence model.
Forecasts beyond 3 days are lower confidence - check back nightly as the outlook firms up.
Aurora visibility by town
Each spot lights up at a different Kp threshold thanks to its latitude. It comes down to the clouds.
Lupul the wolf's tip: Romania sits at 44-48° N - further south than most aurora destinations. A G4 or G5 storm is needed to see aurora from here, meaning Kp 8 or above. The May 2024 storm was visible from the Carpathians, and historical records show these events happen a handful of times each solar cycle, clustering around solar maximum. Dark-sky sites in the Apuseni Mountains or the Bucegi plateau give the best chance when the conditions align.
Three ways to do it
Carpathian Mountains
Retezat NP and Piatra Craiului at 1,500–2,500 m - Bortle 1-2, clearest air in Romania
Threshold · Kp 7Why Romania stands out
Romania is one of the larger countries in Europe where aurora has been credibly documented, and the Carpathians give it a genuine edge over flat terrain at similar latitudes. The mountain chain runs in an arc through Transylvania, and the peaks of Retezat, Piatra Craiului, and the Bucegi range all provide high-altitude dark sky positions accessible by road or short hike. Retezat National Park is particularly remote - designated by the EU as one of Romania's core wilderness areas, it has virtually no light pollution at night.
Romania at 44–47°N magnetic latitude sits at the outer edge of European aurora territory. Kp 7–8 is needed - strong G3–G4 storms. The May 2024 G5 storm produced aurora across the country. The Carpathian Mountains at 1,500–2,500 m elevation are Romania's best aurora positions, with some of the darkest skies in central Europe.
Romania's relatively low overall light pollution - compared with western Europe at similar latitudes - is an advantage when a significant storm does arrive. Clear mountain skies and an unobstructed northern horizon above Transylvanian valleys can produce striking aurora sightings during G4–G5 events, as the May 2024 storm demonstrated.

How often does the aurora appear in Romania?
Average nights per month the Kp reached Carpathian Mountains's threshold, from 15 years of geomagnetic data (2010–2024).
Based on geomagnetic data 2010–2024. Romania needs G3+ storms - events are rare but the Carpathians at elevation give the best possible position for catching low-altitude aurora during active periods.
Plan your trip to Romania
Best window
March and September around the equinox for the highest probability of a G3+ storm. Drive to Retezat National Park or Piatra Craiului - both offer Bortle 1-2 conditions at elevation, with unobstructed northern horizons above the Transylvanian valleys.
Storm-dependent viewing
Aurora in Romania is exclusively storm-dependent. Set NOAA G3+ alerts. When a severe storm is forecast during nighttime hours, drive to elevation in the Carpathians - the journey from Bucharest to Piatra Craiului is about 2 hours.
