Live forecasts update automatically; written guidance last reviewed 16 June 2026 by the Civic Maple Weather Desk. Data from Environment and Climate Change Canada and other national met services via Open-Meteo.
Check the live forecast above to see if aurora activity is expected near you tonight. The northern lights are driven by solar storms, and clear skies with high Kp-index values increase your chances of seeing them.
What is an aurora borealis solar weather watch?
A solar weather watch means space weather agencies have detected solar flares or coronal mass ejections heading toward Earth. When these charged particles reach our atmosphere, they can trigger colourful aurora displays. The watch alerts you to potential visibility in the coming hours or days.
How do I use the aurora forecast for my area?
Check the 3-day aurora forecast from NOAA and your local cloud cover. The live forecast above shows the Kp-index (0–9). A value of 5 or higher often means the aurora borealis may be visible farther south. For Canada, even Kp 4 can produce good shows in northern regions like Yellowknife or Churchill.
What time will the northern lights be visible tonight?
Aurora activity can start after sunset, but peak visibility is usually between 10 p.m. and 2 a.m. Check the live forecast above for real-time Kp readings and local cloud cover on our 10-day forecast page.
Can I see the northern lights in southern Canadian cities?
Is the aurora forecast for my area reliable?
The 3-day aurora forecast from NOAA gives a general outlook, but short-term changes are common. Combine it with local weather on our Canada weather hub to decide if viewing is worth the trip.
