Canada · Aurora borealis
Is the aurora visible in Calgary tonight?
Right now
Not tonight.
Kp is 0.0. Calgary needs Kp 6+ for the oval overhead — right now it’s not reaching Calgary.
Tonight's peak is forecast around Kp 4.0 (Active). The forecast still depends on darkness, cloud and the moon at your exact spot.
Reliable about 30 minutes ahead — cloud decides the rest.
Calgary needs an active night or a minor geomagnetic storm — it needs roughly Kp 6+ for the northern lights to come into view. Here's tonight's live space weather and how to plan around it.
How to see the aurora from Calgary
Face north and find a clear, low horizon in that direction. Everything else — dark skies, adapted eyes, the camera trick — is the same anywhere on Earth, so it lives in the how to photograph the aurora guide.
When can you see the northern lights in Calgary?
Aurora season in Calgary runs roughly September – March. Here the months that pay off are September, May, and March — the table below shows why. See the full best time to see the aurora guide for the season in detail.
Calgary by the numbers
Between Sep 1, 2025 and Aug 31, 2026, Calgary had 365 nights dark enough for the aurora, and the planetary Kp reached the Kp 6+ this place needs on 26 of them. Averaged over 2015–2024 and this location's cloud cover, that works out to about 5 aurora-possible nights a year, most of them in September, May, and March.

|---|---|---|---|---|
| January | 14 h | 31 | 65% | <1 |
| February | 12.8 h | 28 | 67% | <1 |
| March | 11 h | 31 | 63% | 1 |
| April | 8.8 h | 30 | 65% | <1 |
| May | 7 h | 31 | 61% | 1 |

| August | 8 h | 31 | 47% | 1 |
| September | 10.3 h | 30 | 54% | 1 |

Where to watch near Calgary
Get out of the city lights and find a clear view to the north. These are places near Calgary that locals and aurora chasers use. Distances and drive times are from the city centre.
Nose Hill Park (west lot, Shaganappi Trail)
A large grassland plateau in north-west Calgary, rising to about 1,230 m. Its height and open sky make it the easiest in-city option.
City parks are open 5 a.m. to 11 p.m. unless posted. It is surrounded by city light, so expect to see only strong displays.
MapAnn & Sandy Cross Conservation Area
The Royal Astronomical Society of Canada named it a Nocturnal Preserve in 2015, the first in Canada. It sits in the foothills south-west of the city, with far less light than Calgary.
Open 4 a.m. to 11 p.m. only, and closed overnight. Parking is $10 per visit and everyone must sign in at the Welcome Kiosk. No dogs. Calgary's glow lies to the north-east.
MapBig Hill Springs Provincial Park
A small foothills park north-east of Cochrane with open country and wide skies, away from the glow of both Calgary and Cochrane.
Alberta Parks lists it as open year-round but gives no night hours, so check before you go. Parking is free and there are vault toilets. Open fires are not allowed.

Local tips
- City of Calgary parks close from 11 p.m. to 5 a.m. unless a sign says otherwise. Pathways stay open 24 hours.
- Fish Creek Provincial Park is often suggested for aurora, but from October to March its parking lots open only from 8 a.m. to 8 p.m., and the gates may be locked outside those hours.
- Many Albertans use the University of Alberta's free AuroraWatch email alerts. Calgary also has a local Facebook group, Calgary Aurora Chasers, that tracks conditions.
The last big one
: During the May 2024 geomagnetic storm, Calgarians saw green, red and purple aurora from Friday evening into early Saturday, including from inside the city.
