THE NEXT CHASE

Find a little darkness.
Follow the clear sky.

Choose a country, compare the clouds, and find a place to look up. This is the planning desk behind the photographs, with a live aurora model and weather forecasts to help you decide where to begin.

Northern cities, regions and viewing spots. Area pins are approximate forecast references; they do not confirm parking or safe access.

HOW WILL YOU GET THERE?

Showing all viewing spots.

See matching map pins

Walk estimates are one way from each card’s named starting point, not your hotel. Snow and ice can add time. Green pins: nearby walking options · violet pins: drive-first spots. Pins mark approximate viewing access locations, not surveyed parking bays.

Checking what this means…

A southward Bz can favour energy transfer; it is not a sighting guarantee.

Aurora can be visible in Lapland without a major geomagnetic storm. A weak overhead model cell does not rule out aurora near the horizon. Kp, G scale and solar wind measurements describe different things and time periods.

Forecasts are model estimates, not confirmed sightings. Markers distinguish local viewing spots and approximate regional forecast references. Area pins are not verified parking or access points. Darkness descriptions are qualitative, not measured light-pollution ratings. The map currently covers Iceland, Norway, Finland and Sweden. A clear forecast cannot guarantee aurora or safe access.

Sources, times and what the visuals mean

NOAA SWPC supplies Kp, solar wind, magnetic field and the auroral model. MET Norway or Open-Meteo supplies weather. Sun and moon positions are calculated locally. Each chart shows its time range; missing observations leave gaps. Cloud cover is the forecast proportion of sky covered, not a percentage chance of aurora. The planning score combines weather, darkness, moonlight and the near-term aurora model; it is not calibrated against confirmed sightings.

WHERE TO TRY · NEAR TERM

Comparing the sky…

Cloud layers, darkness, moon altitude, wind and the local auroral model are being compared.

How this recommendation works

We compare the marked areas only, not every location in the country. The near term shortlist uses weather within 30 minutes of NOAA’s model time, at most 90 minutes ahead. Sun and moon positions come from SunCalc. Cloud, darkness, moon contrast and wind are combined with the nearest NOAA grid value. The score is an uncalibrated planning heuristic, never a percentage chance of seeing aurora. Heavy cloud, bright twilight, precipitation or strong wind blocks a positive suggestion. No road safety or live sighting data is included.

The later window below ranks weather and darkness over 12 hours. It makes no prediction of auroral activity that far ahead. Access notes describe local lights and approximate travel; the forecast score does not model terrain, actual walking routes or driving time. Check access and official warnings before travelling.

A PLACE TO START

Choose your patch of sky.

The interactive map is loading. Viewing areas and Google Maps links are also listed beside it.
More favourable comparisonLimited conditionsWeather unavailable

The optional NOAA layer shows model grid intensity, not confirmed sightings. The map updates its area colours after forecasts load.

Area markers are approximate planning references. Use Google Maps to inspect access and parking. Respect closures, private land, tide restrictions and road conditions. No live sighting reports have been added.

MOON MAP · SELECTED VIEWING SPOT

Where is the moon?

Choose a map pin to calculate the moon direction.

The line points towards the moon from your spot. It is a compass bearing, not a route or a place to travel to. Hills and trees can block the actual horizon.

WINDOWS INTO THE NORTH

Watch the sky, right here.

Live-provider players; press play if needed. Check the camera’s displayed time. Snow, daylight, clouds or an offline feed can hide the sky; no aurora detection is inferred from these videos.

The northern auroral oval

NOAA northern hemisphere short term aurora forecast; timestamp is printed on the image

NOAA OVATION models auroral location and intensity. It usually offers about 30 to 90 minutes of lead time; fallback inputs can remove that lead. It does not include local cloud cover, landscape or your eyesight. Read the timestamp on the image.

Watch the cloud gaps move

Use Windy’s time controls to compare cloud movement. Surface wind direction in the table is where the wind comes from; it is not a prediction of how every cloud layer will move.

LOCAL OUTLOOK

The next twelve hours.

Times use the selected location’s time zone. Darkness here means the model labels the hour as night; twilight may still be too bright. Cloud cover percentages describe forecast sky coverage, not your chance of seeing aurora.

ROY’S WAY OF LOOKING

The numbers start the evening. Patience makes it.

Find a gap

Compare low, middle and high clouds, then watch the next few forecast hours. A small clear patch nearby can be more useful than a bigger activity number under solid cloud.

Work with the moon

Moonlight can soften a faint display and illuminate a beautiful foreground. Check whether the moon is above the horizon. A bright moon is not an automatic reason to stay inside.

Give it time

Find legal, safe access away from bright lamps and let your eyes adjust. Keep checking the sky between pictures. If you drive, check local warnings and the return journey before setting out.
