Find My Climate Zone
Enter your postcode to find your likely climate zone, and set it site-wide so every guide shows the right advice for you automatically.
Postcode Lookup
This maps your postcode to one of six broad Australian climate zones used throughout this site. It's a useful starting point, not a precise local forecast — see the section below for why.

Why This Is a Starting Point, Not a Guarantee
Australia's climate doesn't follow postcode boundaries — it follows elevation, distance from the coast, and latitude, none of which postcodes were ever designed to capture. Two postcodes right next to each other can sit either side of a climate difference, particularly around the Great Dividing Range, where a town in a valley and a town on the nearby tableland can have different growing seasons despite being postally close. This tool uses broad, honest regional patterns to give a sensible starting zone, but if you know your local conditions run noticeably warmer or cooler than what it suggests — frost patterns, elevation, coastal influence — trust your own experience and use the zone picker in the menu to override it manually.
What the Six Zones Actually Mean
This site uses six broad Australian growing zones, since they map cleanly onto different planting calendars: Tropical (Darwin and the NT Top End, far north QLD from Townsville up, the WA Kimberley — hot and humid year-round, a wet season and dry season rather than four seasons, frost essentially never happens), Subtropical (Brisbane and coastal QLD, far north coastal NSW — warm winters, humid summers, minimal frost risk), Warm Temperate (Sydney basin and most of coastal NSW — mild winters, rarely severe frost), Mediterranean (Adelaide and southern SA, Perth and the WA South West — wet winters and hot, dry summers, the reverse rainfall pattern from most other zones), Cool Temperate (Tasmania, Victoria, the ACT, and the highlands/tablelands of NSW — frosts, a clearly defined winter dormancy), and Arid (Alice Springs and Central Australia, far western NSW, the Mallee, SA's far north, WA's Goldfields and eastern interior — hot dry summers, minimal and unreliable rainfall, irrigation matters more than calendar timing).
Frequently Asked Questions
Why isn't this precise for every postcode?
Climate is driven by elevation, coastal proximity, and latitude, not postal boundaries, so any postcode-based tool is necessarily an approximation. It's most useful as a sensible starting point, refined by your own local experience.
What happens when I find my zone here?
It's set site-wide using the same zone picker found in the menu on every page — grow guides, planting calendars, and other zone-aware content will automatically show you the right advice from then on.
Can I override the zone this tool suggests?
Yes, any time — use the zone picker in the site menu to manually set a different zone if you know your local conditions differ from the general regional pattern.
Which zone covers the most of Australia's population?
Warm Temperate and Mediterranean between them cover most capital cities (Sydney is Warm Temperate; Adelaide and Perth are Mediterranean), followed by Cool Temperate (Melbourne, Hobart, Canberra), Subtropical (Brisbane), and Tropical (Darwin).
