HF DX CONDITIONS — OCEANIA
Tuesday 29 September to Monday 5 October 2026
Overall, HF conditions across Australia, New Zealand and the Pacific should be fair to good for most of the week, with quiet geomagnetic conditions supporting stable propagation through Saturday.
Space-weather outlook
Solar flux: Approximately 105–115
29 September–3 October: Mostly quiet, with Kp around 2
4 October: Activity may increase to Kp 3
5 October: Unsettled to active periods possible, reaching Kp 4
Solar activity is expected to remain very low to low
No significant radio blackouts or solar-radiation storms are currently expected
The Australian Space Weather Forecasting Centre presently reports normal solar, geomagnetic and ionospheric conditions, with no HF communications warning current.
Band-by-band outlook
160 and 80 metres
Best after dark and around sunrise. Expect good local and regional coverage, with occasional longer-distance contacts during quiet nights. Tropical and storm noise may remain an issue in northern Australia and the Pacific.
40 metres
Likely to be one of the week’s most reliable bands. Regional contacts should be available from late afternoon through the night, with good DX potential toward Asia, North America and occasionally Europe around greyline.
30 metres
A strong choice for long-distance CW and digital operation. Look for openings during the evening, overnight and around sunrise.
20 metres
The main daytime DX band this week. Expect useful openings toward Asia and the Pacific during the day, extending toward North America and Europe around the morning and evening greyline periods.
17 and 15 metres
Fair daytime prospects, especially from Wednesday through Friday when solar flux is forecast near 115. Openings may be selective but could produce strong signals toward Asia, North America and across the equatorial Pacific.
12 and 10 metres
Openings are possible but should not be considered dependable. Check during late morning and afternoon, particularly on north–south and trans-equatorial paths. Brief evening openings may also occur.
Best opportunities
Asia: Daytime on 20–15 metres; evening and night on 40 metres
North America: Late afternoon through evening on 20 metres, moving to 40/30 metres after dark
Europe and Africa: Greyline on 20 metres, with 30 and 40 metres favoured overnight
South America: Watch 20 and 17 metres near greyline
Pacific islands: Good regional coverage on 20 and 40 metres, with higher-band openings during daylight
Operator’s tip
Make the most of the quiet period through Saturday. Conditions may become more unsettled on Sunday and Monday as a recurrent coronal-hole solar-wind stream arrives. If Kp rises, favour lower-latitude paths and 20–40 metres, while checking higher bands frequently for short-lived openings.
