How to Read an Aurora Forecast
An aurora forecast is easier to read when you know what matters most: geomagnetic activity, darkness, cloud cover, and your location. Here is how to turn the numbers into a better yes-or-no decision.
Narva can occasionally see the northern lights during stronger geomagnetic activity, provided the sky is clear and the northern horizon is dark.
Unlikely tonight

Local viewing guide
At roughly 59.4° north in Ida-Viru County, Narva can see the northern lights when geomagnetic activity becomes strong enough to move the aurora farther south. Displays are occasional rather than routine and may begin low on the northern horizon. Narva’s northeastern position gives it one of Estonia’s more favorable latitudes for an occasional aurora display.
Narva is relatively compact, which can make darker surroundings easier to reach than in a large city. Local streetlights still matter, so find a safe open view and keep bright lamps outside your immediate line of sight.
Longer nights from autumn through early spring provide the best opportunity to notice a faint display. Darkness alone is not enough, though; the aurora forecast must strengthen and the local sky must stay clear at the same time.
Aurora conditions can change during the night, so keep checking the forecast rather than relying on an earlier reading. From Narva, the best plan combines clear weather, an unobstructed northern horizon, patience, and as little artificial light as practical.
The current aurora chance for Narva is None. Use the local viewing guide above for Narva-specific context, then combine the live rating with darkness and weather.
A none or near-none chance in Narva usually means tonight is not a strong aurora setup for this location. It is still useful context, because you can compare later updates or look at cities farther north for better odds.

Aurora forecasts can be useful, but they are never perfect. Solar activity, magnetic-field direction, cloud cover, and local darkness all make the northern lights harder to predict than most people expect.
The KP index is one of the most common numbers in aurora forecasts, but it works best as a rough guide, not a promise. Here is what it means and how casual northern lights watchers should use it.
