If you have been hearing people talk about the northern lights and wondering whether you might be able to see them tonight, you are in excellent company. Searches for “northern lights tonight” have surged by over 600% in the past 10 hours, sending more than 20,000 people to Google hunting for aurora forecasts, viewing locations, and tips on how to actually see this breathtaking natural phenomenon. Here is everything you need to know.
Why Are the Northern Lights Visible Tonight?
The northern lights — technically known as the aurora borealis — are caused by charged particles from the sun interacting with gases in Earth’s atmosphere. When the sun emits particularly strong bursts of energy, known as solar flares or coronal mass ejections (CMEs), these charged particles travel toward Earth at incredible speeds and collide with atmospheric gases to produce the stunning light displays we know as the aurora.
Right now, we are in an active period of solar activity, with the sun approaching or having recently passed solar maximum — the peak of its approximately 11-year solar cycle. During solar maximum, the frequency and intensity of solar flares increases significantly, which means more opportunities for spectacular aurora displays at lower latitudes than usual.
Where Can You See the Northern Lights Tonight?
Normally, the aurora borealis is primarily visible in a band around the Arctic Circle — places like Alaska, Canada, Iceland, Norway, Finland, Sweden, and Scotland. But during particularly strong geomagnetic storms (classified on a scale from G1 to G5, with G5 being the most extreme), the aurora can become visible much further south than usual.
During moderate to strong geomagnetic storms (G2 and above), aurora sightings have been reported across the northern United States, including states like Minnesota, Michigan, Wisconsin, Maine, Montana, and the northern parts of the Pacific Northwest. During exceptional storms (G4-G5), the aurora has even been spotted as far south as Texas, Florida, and Mexico in recent years.
To find out exactly what the aurora forecast looks like for your area tonight, the best resource is NOAA’s Space Weather Prediction Center at swpc.noaa.gov, which publishes near-real-time aurora forecasts and geomagnetic storm alerts. The SpaceWeatherLive website and app are also excellent resources with user-friendly aurora forecast maps.
How to Maximize Your Chances of Seeing the Aurora
Seeing the northern lights requires a combination of good timing, the right conditions, and a little patience. Here are the key factors that determine whether you will actually get to witness this phenomenon:
Darkness is essential. You need to be away from city light pollution as much as possible. Even moderate amounts of light pollution can completely wash out a faint aurora display. The darker your surroundings, the better your chances. Head out to the countryside, a state or national park, or any open area well away from urban centres.
Clear skies are non-negotiable. Clouds will block your view entirely, no matter how active the aurora is overhead. Check a detailed cloud cover forecast for your area before heading out — weather apps like Clear Outside are specifically designed for astronomical observation and will give you a much more detailed cloud forecast than standard weather apps.
Time your viewing right. The aurora is most active around local midnight, though it can be visible from late evening through to early morning. Give your eyes at least 20-30 minutes to adjust to the darkness before you decide the aurora is not visible — dark adaptation takes time and makes a significant difference to what you can see.
Use your phone camera. Modern smartphone cameras are genuinely better at picking up aurora light than the naked eye because they can collect light over multiple seconds in night mode. If you suspect there might be an aurora but cannot quite see it, point your phone camera at the northern horizon and take a long-exposure shot. You might be surprised at what shows up in the image even when the aurora appears very faint to the naked eye.
What Colors Will You See?
The colors of the aurora depend on which gases in the atmosphere are being excited by the solar particles and at what altitude the collisions are occurring. The most common color is green, which comes from oxygen molecules at altitudes of around 60-150 miles. Red auroras occur at higher altitudes and are rarer. Blue and purple hues come from nitrogen molecules and are often visible at the edges or lower parts of the display. Truly spectacular displays can show all of these colors simultaneously, creating curtains and ribbons of light that dance across the entire sky.
Photographing the Northern Lights
If you want to capture the aurora properly with a dedicated camera, use manual mode, set your aperture as wide as possible (f/1.8 to f/4 is ideal), set your ISO to between 800 and 3200 depending on the brightness of the aurora, and use an exposure time of between 5 and 25 seconds. A tripod is absolutely essential to avoid camera shake. Experiment with different settings — every aurora display is different, and what works on one night may not work on another.

The Bottom Line
The northern lights are one of the most awe-inspiring natural spectacles on Earth, and tonight represents a real opportunity for many people across the northern United States and Canada to witness them firsthand. Check the NOAA forecast, get away from city lights, make sure the skies are clear, and head out around midnight. You might just witness something you will remember for the rest of your life.
