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 three broad Australian climate zones used throughout this site. It's a genuinely 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 real climate difference, particularly around the Great Dividing Range, where a town in a valley and a town on the nearby tableland can have genuinely 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 Three Zones Actually Mean
This site uses three broad Australian growing zones rather than a more complex system, since they map cleanly onto genuinely different planting calendars: Cool Temperate (Tasmania, Victoria, the ACT, and the highlands/tablelands of NSW — real frosts, a clearly defined winter dormancy), Warm Temperate (Sydney basin, most of coastal NSW, Adelaide and southern SA, Perth and the WA South West — mild winters, rarely severe frost), and Subtropical (Brisbane and coastal QLD, Darwin and the NT Top End, northern WA — warm winters, humid summers, minimal frost risk).
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 covers the most capital cities (Sydney, Adelaide, Perth), followed by Cool Temperate (Melbourne, Hobart, Canberra) and Subtropical (Brisbane, Darwin).
