Aurora tonight in Whitehorse

Can you see the aurora borealis from Whitehorse?

Whitehorse sits close enough to the auroral oval that the northern lights are a routine winter occurrence rather than a special event.

Whitehorse is unusually dry for its latitude. The Yukon interior sits in the rain shadow of the coastal mountains, so the skies here are clear far more often than in coastal Alaska or Norway — which is the real reason Yukon has built a winter aurora industry on a Kp 2 threshold rather than a lower one.

When to look: the Whitehorse aurora season

Work from **26 Aug** to **16 Apr**: that is the stretch in which Whitehorse gets a properly black sky, 234 nights in all. Outside those dates the sun never drops the full 18° below the horizon, so some twilight stays in the sky whatever the geomagnetic forecast says. The counter-season is just as clearly defined: from about **17 Apr** to **25 Aug** (131 nights) the sun never gets 18° below the horizon, so the sky never reaches full darkness, and between roughly 6 May and 6 Aug it does not get properly dark at all — no display, however strong, is visible in that stretch.

Judge the season by the sun rather than the calendar at Whitehorse: 52.7° below the horizon on the darkest night, but never a full 18° between roughly 17 Apr and 25 Aug. Those are the nights when the aurora can be overhead and still invisible.

Where to go in Whitehorse

The surrounding hills give you height without distance; a short climb out of the valley puts you above the town lights and under open sky in every direction.

Face north. Auroral light comes from the oval that rings the magnetic pole, and from Whitehorse that ring lies to the north — so a rooftop, a treeline or a bright shopfront on that side costs you the display no matter how good the forecast is. As for timing, the "best window" figure near the top is the first hour where cloud sits below about 40% during this latitude's darkness.

What Kp do you need in Whitehorse?

Here is what each Kp value would actually put in Whitehorse's sky — the row that matters is the one at Kp 2, which is where this city's magnetic latitude of 64° places its threshold:

The most common reason people miss a display at this latitude is timing rather than strength: a Kp 2 night is enough, but substorms come and go inside a single Kp interval, so a 20-minute gap in your attention can be the whole show. Check the sky every 20–30 minutes rather than once.

How tonight's answer is calculated for Whitehorse

The score above is built from five weighted factors, each using Whitehorse's own figures rather than a regional default: Kp against a local threshold of 2 (35%), cloud cover averaged across the dark hours at 60.72°, -135.05° (25%), moon illumination (15%), this latitude's astronomical darkness window (15%) and Bortle 3 light pollution (10%).
