The 2027-28 Australian Cyclone Season Opens
- The official tropical cyclone season in the Australian region runs from 1 November to 30 April. [S]
- On average there are 10 tropical cyclones in the region each season, with three or four making landfall. [S]
- Most cyclones form inside the November-to-April window, but some form outside it, so the Bureau's statistics use a full 12-month July-to-June season. [S]
- The earliest cyclone on record to cross the coast did so on 21 November 1973 — Severe Tropical Cyclone Ines. [S]

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
