Why these months?
Two things decide your odds in Bruny Island: darkness and activity. You need real darkness — so the bright summer months are out no matter how strong the aurora is. On top of that, geomagnetic storms run statistically stronger around the spring and autumn equinoxes (the Russell–McPherron effect), which is why June and July and May tend to edge out the dead of winter. Bruny Island's season runs southern winter — april to september.
Bruny Island is a short ferry ride south of Hobart and a genuine step further from the city's light dome — the standard escape for Tasmanian aurora watchers when a storm alert lands.
Where to stand in Bruny Island
Cloudy Bay and the isthmus at the Neck both open straight south over the Southern Ocean. Check the last ferry before you plan an all-night session.
