Melbourne Climate Zone and Building Design Data
Melbourne is listed in NCC climate zone 6 (mild temperate); BOM station 086282 at Melbourne Airport provides an open, long-running public reference record but is not automatically representative of every metropolitan site.

Direct answer
Use NCC Zone 6 as Melbourne's code-zone starting point, confirm the exact address in the ABCB map and record Victoria's applicable NCC edition. For climate analysis, document why Melbourne Airport station 086282 or another weather source represents the project; its monthly means are context, not plant-sizing conditions.
Code-zone baseline
NCC Online lists Melbourne in climate zone 6, which the ABCB describes as mild temperate. Confirm the site's address or coordinates in the ABCB Climate Map, then identify the volume, building classification, compliance path and jurisdictional provisions that apply. Zone 6 is a routing input into those provisions; it is not a thermal model or a design-temperature table.
Public station profile with its limits attached
The BOM climate table for Melbourne Airport, station 086282, locates the station at 37.67 °S, 144.83 °E and 113 m elevation. It opened in 1970 and remains open. The live table reviewed on 26 August 2026 reports 56 years of available temperature and rainfall statistics spanning 1970–2026.
| Public climate cue | Early design use | Required next step |
|---|---|---|
| January mean max/min: 26.7/14.0 °C | Test solar control, diurnal operation and whether night cooling is plausible | Use an approved hourly file and project constraints |
| July mean max/min: 13.2/5.5 °C | Prioritise heat loss, airtightness, cold-surface comfort and condensation analysis | Model assemblies and junctions for the actual indoor moisture load |
| Annual mean max/min: 20.0/9.6 °C | Establish broad seasonal context | Do not use for equipment sizing |
| Mean annual rainfall: 536.2 mm | Keep durable water-shedding and drainage strategies visible | Obtain local intensity, exposure and authority requirements |
An airport record is transparent and reproducible, but the CBD, bayside suburbs, eastern hills and urban fringe can differ in exposure, elevation and urban heating. The station choice should be a written decision, not an invisible software default.
Design implications worth testing
Melbourne's seasonal and short-term variability rewards envelopes and controls that work in more than one mode. External shading should reduce unwanted summer gain while preserving useful winter sun and daylight. Airtightness and thermal-bridge control influence winter energy and internal surface temperatures; operable ventilation requires an hourly test of temperature, wind, rain, noise, security and outdoor air quality. Thermal mass is beneficial only when solar admission and night-time heat rejection are controlled.
Use the public station values to form those questions, then test them in the project's approved energy workflow. A monthly mean cannot show a heatwave sequence, a cold still morning or simultaneous temperature and humidity.
Victoria's edition transition is part of the climate brief
The Victorian Government building-standards page says Victoria adopted NCC 2025 on 1 May 2026. It also describes transition treatment for work whose design or construction had already commenced. Record the project's design commencement, permit pathway, surveyor decision and Victorian variations rather than assuming the publication year settles applicability.
This is especially important when comparing precedent details or energy targets produced under NCC 2022 with a project assessed under NCC 2025. The climate zone may be unchanged while the governing provisions or referenced documents differ.
Do not derive missing design values
No peak heating or cooling condition is inferred here from the BOM table. The responsible engineer or modeller should record the exact station or weather file, variable, percentile or recurrence criterion, source edition, units and any adjustment. The same separation applies to wind, rainfall intensity, flood, bushfire and corrosion data, each of which has its own site-specific source.

Complete this board at concept design, then attach the evidence used by the energy modeller and services engineer.
| Investigation | Baseline cue | Project question | Evidence to attach |
|---|---|---|---|
| NCC pathway | Melbourne is listed as Zone 6 | Does the address lookup confirm Zone 6 and which NCC edition applies? | ABCB map capture; Victorian transition decision |
| Station fit | Melbourne Airport 086282: 37.67 °S, 144.83 °E, 113 m | Is an airport station representative of the site's elevation, coast/inland position and urban context? | Station comparison and selection note |
| Summer control | January mean max/min 26.7/14.0 °C | Which orientations need external shade without sacrificing winter daylight? | Hourly sun/shade and thermal model |
| Winter comfort | July mean max/min 13.2/5.5 °C | Where are conductive loss, infiltration and cold internal surfaces most likely? | Envelope sections, junction review and model |
| Rain response | Mean annual rainfall 536.2 mm at station | How will facade exposure, drainage and local intensity be resolved independently? | Local hazard sources and water-management details |
| Natural ventilation | Large day-to-day and seasonal variability is hidden by means | When are temperature, wind, noise and air quality all acceptable? | Hourly weather file and operating-mode study |
| Plant inputs | Not supplied by monthly climate means | Which exact design variables and percentiles govern? | Engineer's source/edition/station schedule |
Review gate: do not convert the public means above into design temperatures. Record the modelling weather file separately from the NCC zone and engineering design-condition source.

Frequently asked questions
What NCC climate zone is Melbourne in?
The NCC location table lists Melbourne as climate zone 6, described by the ABCB as mild temperate. Confirm the project address or coordinates in the current ABCB Climate Map and retain the lookup, especially for a metropolitan-fringe or elevated site.
Is Melbourne Airport the correct weather station for every Melbourne project?
No. Station 086282 is an open BOM station with a substantial public record, but it is at 113 m elevation and an airport setting north-west of central Melbourne. Compare it with the site and other available stations or approved weather files, then document the selection for each analysis.
What do Melbourne's January and July means tell an architect?
They provide seasonal context: at station 086282 the January mean maximum/minimum is 26.7/14.0 °C and July is 13.2/5.5 °C. They support early questions about shading, thermal mass, ventilation and winter surface temperatures, but they do not represent extremes, hourly sequences or HVAC design conditions.
Does NCC 2025 apply to a Melbourne project?
Victorian Government guidance says Victoria adopted NCC 2025 on 1 May 2026 and describes transitional treatment for projects whose design or construction had already commenced. Confirm the precise application of that transition, Victorian variations and the approval date with the building surveyor.
