Map of Northern Lights – Aurora Forecast & Viewing Guide
Map of Northern Lights - Aurora Borealis Forecast, Locations and Viewing Guide
Explore where the Northern Lights can be seen, how to interpret an aurora forecast map and what conditions improve your chances of seeing them. This guide covers northern viewing regions, the auroral oval, geomagnetic activity, seasonal darkness and practical skywatching advice.
Quick answer: Where can you see the Northern Lights?
The Northern Lights, or aurora borealis, are most often seen at high northern latitudes, including northern Norway, Sweden, Finland, Iceland, Alaska and northern Canada. They form when energetic particles interact with gases in Earth's upper atmosphere. Visibility depends on auroral activity, darkness, cloud cover and your location. During strong geomagnetic storms, auroras can be seen farther south than usual.
Interactive Northern Lights Forecast Map
NOAA's Space Weather Prediction Center provides a short-range aurora forecast showing where auroral activity is expected around the northern and southern magnetic polar regions. It is an estimate, not a guarantee that a display will be visible from a particular town.

How to Read an Aurora Forecast Map
- Choose the Northern Hemisphere: The North polar map is for aurora borealis; the South polar map is for aurora australis.
- Find the auroral oval: A broad ring of predicted activity usually surrounds the geomagnetic pole, not exactly the geographic North Pole.
- Compare the colours: NOAA's map generally uses green for the auroral oval and red for greater predicted intensity. Consult its legend rather than treating colour as a certainty.
- Check darkness: A predicted aurora may be invisible in daylight and difficult to see in twilight.
- Check local weather: Clouds, moonlight, haze and urban lighting can hide even strong auroral activity.
- Look toward the pole: From locations south of the auroral oval, a strong display may appear near the northern horizon rather than overhead.
Important: NOAA's forecast shows modelled auroral activity; it is not a live camera and does not account for every local viewing obstruction.
Best Northern Lights Viewing Regions
These areas are known for high-latitude aurora viewing opportunities. Visibility varies from night to night and does not depend on location alone.
| Region | Examples | Viewing considerations |
|---|---|---|
| Northern Norway | Tromso, Alta, Lofoten | High-latitude access; coastal cloud and weather can affect views |
| Northern Finland | Inari, Saariselka, Finnish Lapland | Dark inland areas can offer good skywatching conditions |
| Northern Sweden | Abisko, Kiruna | Good access to high-latitude viewing away from major city lights |
| Iceland | Rural areas outside Reykjavik | Long winter darkness; changeable clouds and weather |
| Alaska, USA | Fairbanks and nearby dark-sky areas | Accessible inland aurora viewing; extremely cold conditions possible |
| Northern Canada | Yellowknife, Yukon, northern territories | Frequent high-latitude viewing opportunities with sufficient darkness |
| Greenland | Communities with accessible dark skies | Strong seasonal daylight differences and challenging travel conditions |
What Causes the Northern Lights?
The Sun releases a continuous solar wind of charged particles. Changes in the solar wind and its magnetic field can disturb Earth's magnetosphere, allowing energetic particles to precipitate into the upper atmosphere. Interactions with oxygen and nitrogen excite these gases, which then emit light as they return to lower-energy states.
The lights can form moving arcs, curtains, rays and diffuse glows. Their shapes change as magnetic and atmospheric conditions evolve.
Why Are Auroras Green, Red or Purple?
- Green: Commonly produced by excited oxygen at typical auroral altitudes.
- Red: Often associated with oxygen emissions at higher altitudes and can be noticeable during strong displays.
- Blue and violet: Can be associated with nitrogen emissions and mixed colours.
- Pink or white appearances: Multiple emissions, brightness and human night vision can influence the colours observers perceive.
Cameras can capture stronger colours than the unaided human eye, especially in faint displays.
What Is the Auroral Oval?
The auroral oval is a broad region of auroral activity encircling each geomagnetic pole. It expands and shifts during increased geomagnetic activity, so the Northern Lights can sometimes be seen well beyond the usual Arctic viewing regions. Geographic latitude alone does not determine visibility: geomagnetic position also matters.
Understanding the Kp Index
The planetary Kp index is a measure of geomagnetic activity from 0 (quiet) to 9 (extreme). It is a useful broad indicator, but not a local promise of an aurora sighting.
| Kp range | General interpretation |
|---|---|
| 0-2 | Quiet conditions; aurora usually closer to geomagnetic poles |
| 3-4 | Increased activity; good displays possible at favourable high-latitude locations |
| 5-6 | Geomagnetic storm conditions; possible visibility farther from the poles |
| 7-9 | Strong to extreme activity; potential for auroras at unusually low latitudes |
The auroral oval, actual cloud cover and sky darkness are still important even if Kp is high.
When Is the Best Time to See Northern Lights?
Autumn through early spring offers long dark nights at many northern viewing destinations. Periods around the September and March equinoxes can also favour geomagnetic activity. Midnight and the hours around it are commonly recommended, but auroras can appear earlier or later in the night.
No particular month guarantees a display. Very high northern latitudes have continuous summer daylight or bright twilight, which makes auroras difficult or impossible to see even when they occur.
Northern Lights vs Southern Lights
Aurora borealis describes auroras around the Northern Hemisphere's geomagnetic pole. Aurora australis describes similar displays around the southern geomagnetic pole. Both are driven by interactions between solar activity and Earth's magnetic environment.
In Australia, viewers are looking for the Southern Lights rather than the Northern Lights. Tasmania and parts of southern mainland Australia can sometimes experience displays during favourable geomagnetic conditions.
Practical Aurora Viewing Checklist
- Consult an up-to-date aurora forecast close to your intended viewing time.
- Check local cloud forecasts and seek a dark, unobstructed horizon.
- Allow your eyes time to adjust to the dark and avoid bright phone screens.
- Check the Moon's phase and position, as moonlight can wash out faint displays.
- Dress for potentially severe weather and follow local travel and road safety advice.
- For photographs, use a stable camera or tripod and experiment with night settings.
Frequently Asked Questions
Where are Northern Lights most often visible?
They are most common across auroral regions near the northern geomagnetic pole, including parts of Scandinavia, northern Canada, Alaska, Greenland and Iceland.
Can you see Northern Lights without a camera?
Yes. Bright auroras are visible to the unaided eye, although faint displays can look less colourful than photographs.
Do the Northern Lights happen every night?
Auroral activity occurs frequently in polar regions, but visibility from any location depends on darkness, geomagnetic conditions, clouds and local geography.
Can Northern Lights appear south of the Arctic?
Yes. During strong geomagnetic storms, the auroral oval can expand, allowing auroras to be visible farther south than usual.
Does a high Kp guarantee Northern Lights?
No. Kp describes widespread geomagnetic activity, not the exact visibility from your location or the presence of clear skies.
What does the NOAA aurora map show?
It shows a short-term model estimate of the location and intensity of auroral activity around the geomagnetic poles.
Are the Northern Lights dangerous to watch?
The visible light display can be watched with the unaided eye. However, extreme weather and travel in remote areas can present hazards, and significant space weather can disrupt technology.
Can you see the Northern Lights from Australia?
No, not the northern aurora. Australians may sometimes see the related Southern Lights, or aurora australis, particularly from southern regions during suitable geomagnetic activity.
