Storm level needed
Warrnambool sits at 38.38S 142.49E in Victoria, Australia. The IGRF-14 centered dipole puts Warrnambool at 45.7 degrees geomagnetic latitude, 7.3 degrees closer to the magnetic pole than its map latitude suggests. Warrnambool sits at 45.7 degrees geomagnetic. The lowest NOAA storm level whose typical viewing latitude reaches it is G4 (Kp = 8, including a 9-). Even Kp 9 does not put the average oval edge overhead by SWPC's rule.
"aurora has been seen as low as Alabama and northern California (typically 45° geomagnetic lat.)"
The nearest other Glow towns are Hamilton, Victoria (82 km), Colac (96 km), Torquay (160 km). Hamilton, Victoria sits 0.6 degrees lower on the dipole and needs the same Kp.
Approximate: SWPC calls its Kp to latitude rule an average, and a centered dipole can differ by a degree from fuller field models. How the storm level is matched
The year in darkness
Every night of 2026 at Warrnambool has some civil darkness; the shortest month sample still has 8.0 hours. Every evening of the year at Warrnambool clears Glow's dark-season bar of 4 hours of civil night between 18:00 and 06:00. Warrnambool's longest night of the year, Jun 16, has 13 h 26 min of civil night.
Solar midnight at Warrnambool, when the sun is lowest, falls at 01:25 on local clocks on December 15 and 00:30 on June 15. That is 1 h 25 min after midnight in December and 30 min after midnight in June, the gap set by daylight saving and the equation of time. So at Warrnambool the darkest hour sits late in SWPC's 10 PM to 2 AM window.

By the 15th-of-the-month sample, June is the darkest month at Warrnambool with 13.4 hours of civil night and December the lightest at 8.0. Across the year Warrnambool gets 3,962 hours of civil night. Astronomical night at Warrnambool, the sun 18 degrees or more below the horizon, lasts 5.2 hours on December 15.
NASA POWER's 2001 to 2020 all-hours climatology puts mean cloud amount for the 1 degree cell around Warrnambool at 62% across the year, from 55% in January to 65% in June. In the months with at least 4 hours of civil night Warrnambool averages 62%, against a median of 60% for Glow towns in Australia.
Multiplying civil night by the clear share of the sky gives June the best score, 4.7 hours, ahead of May at 4.6. Warrnambool's equinox months score 4.5 in March and 4.0 in September, the weeks SWPC links with larger storms.
Kp history
No whole Kp value puts the average oval edge over Warrnambool by SWPC's rule, so the GFZ record has no threshold to count. SWPC's G4 row gives the typical latitude where aurora has been seen.

Moon, next 30 nights
Over the 30 nights from Oct 2, the new moon falls on Oct 11 and the full moon on Oct 26, in Australia/Melbourne dates. 16 of the 30 nights at Warrnambool have at least 2 moon-free dark hours inside 10 PM to 2 AM, and Oct 4 has the most at 4 h. Tonight Warrnambool has 10 h 29 min of civil night, 6 h 11 min of it with the moon down.
