Wait for an alert; do not book a week

At Kp 9, Hobart needs a severe geomagnetic storm before anything shows above the southern horizon. Storms that size arrive a handful of times per solar cycle and announce themselves a day or two ahead. Watching for one beats picking dates and hoping.

Getting clear of the light

With 252,639 people around you, the sky over central Hobart is Bortle 7. The glow hides anything but the brightest display, so the drive out matters more here than the forecast does.

The months that actually deliver

Counting only nights that were both stormy enough and dark enough, May came out ahead in Hobart. That is storm season and darkness overlapping — the equinoxes tend to be geomagnetically active, and the nights are already long by then.

Darkest nights of the coming year

A bright moon washes out a weak display as effectively as street lighting. These new moons fall inside the Hobart viewing season.

Where it is close to a certainty

If you would rather plan a trip than wait for a storm, the nearest place with genuinely frequent aurora is Invercargill, 1,703 km east-south-east in New Zealand.

Where the horizon opens up near Hobart

The display sits low on the southern horizon, so what beats a better forecast is open ground facing that way. Height gets you above the town glow; water gives you an unbroken skyline. These are within a short drive of Hobart.

Places to watch from

Named viewpoints and reserves near Hobart that sit outside the worst of the light. Each puts the southern horizon over open ground instead of over rooftops.

What to do with the daylight

Aurora watching is a night job, and in winter that leaves a short, bright day to fill. Hobart keeps its fortified past above ground, at Beaumaris Zoo Site, Yard 3 and Yard 4, and for a day when the cloud sits low, Tasmania Police Museum, Gatekeeper Cottage and Tasmanian Transport Museum are indoors and near by.

Keep the daylight loose: the sky decides the evening, and the forecast can turn within a few hours.

Where to stay

Staying central in Hobart is fine for everything except the aurora itself — you will still need to drive out. If seeing it matters more than convenience, base yourself on the edge of town facing your dark spot.

Common questions about the aurora australis in Hobart

Can you see the aurora australis from Hobart?

Rarely. Across 10.0 years of NOAA Kp records, Hobart averaged under one night a year where the storm was strong enough and the sky was dark enough at the same time.

What Kp index do you need to see the aurora australis in Hobart?

Kp 9. Hobart sits at geomagnetic latitude -49.7°, and the auroral oval only reaches that far from the pole once activity hits Kp 9. Storms that size occur about 0.1 nights a year.

When is the best time of year to see the aurora australis in Hobart?

May. Those months scored highest once both conditions are counted together: geomagnetic activity and enough hours of real darkness.

Where can you escape the light pollution near Hobart?

The centre of Hobart reads Bortle 7. The nearest sky at Bortle 2 is about 16 km north-north-west. On a marginal night that drive matters more than the forecast does.

Where is the nearest place to Hobart with reliable aurora australis?

Invercargill, New Zealand — 1,703 km east-south-east. It needs only Kp 9 and averages 0.1 viable nights a year against 0.1 in Hobart.
