## Key facts

| Fact | Value |
| --- | --- |
| NASA POWER climatology | 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020) (API v2.9.7; LST) |
| Annual mean temperature | 14.7 °C (2 m gridded climatology; not a design percentile) |
| Highest monthly maximum | 41.9 °C (January) (monthly climatological statistic) |
| Lowest monthly minimum | 1.0 °C (August) (monthly climatological statistic) |
| Annual relative humidity | 74.1% (2 m gridded climatology) |
| Annual corrected precipitation | 1.96 mm/day (climatological daily rate) |
| Annual wind speed | 4.60 m/s (10 m gridded climatology; not a structural design wind speed) |

## Direct answer

NASA POWER's 2001–2020 climatology at the Point Cook reference point reports an annual mean 2 m temperature of 14.7 °C and relative humidity of 74.1%. The highest monthly maximum is 41.9 °C in January, while the lowest monthly minimum is 1.0 °C in August; these are screening statistics, not code design temperatures. The point response uses LST and the 20-year Meteorological and Solar Monthly & Annual Climatologies (January 2001 - December 2020); its annual corrected precipitation is 1.96 mm/day and annual 10 m wind speed is 4.60 m/s. For climate design data, use the 41.9 °C and 1.0 °C monthly extrema to screen seasonal exposure, then obtain the adopted percentile design conditions. NASA POWER is gridded climatology: verify elevation, microclimate, urban exposure, station or weather-file suitability, current code edition and the authority's required source before design use.

## What must be verified for Point Cook?

Point Cook is represented here at approximately **-37.9148, 144.7509** for discovery and workflow planning. A project address, parcel, elevation, exposure, authority, and submission date must replace that city-centre reference before design use.

## How should climate design data be established?

1. Fix the surveyed site and local time basis.
2. Select an authoritative weather source or a named solar-position algorithm.
3. Record period, percentile or scenario and units.
4. Test sensitivity to elevation, exposure, urban form and horizon.
5. Save the source file, retrieval date and checker in the model record.

| Input | Project-specific evidence | QA question |
| --- | --- | --- |
| Site | surveyed coordinates, elevation and horizon | Does the point represent the building? |
| Weather/solar method | named dataset, algorithm, period and time basis | Are station, time zone and units explicit? |
| Design scenario | current and future scenario agreed by the team | Is an average being mistaken for an extreme? |
| Compliance | adopted local document and edition | Was applicability confirmed with the authority? |

## What are the limits of this worksheet?

This climate-design-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Point Cook site remain authoritative.

## Which related searches does this primary location record cover?

This primary route consolidates the location evidence needed for **Climate Design Data**, **Weather File Guide**, **Overheating Weather Data**, **Building Climate Checklist**. A narrower route should be released only when it adds a materially different official source, calculation, process, threshold or worked example.

## Frequently asked questions

### What does NASA POWER climatology show for Point Cook?

For the Point Cook reference point, the 2001–2020 NASA POWER climatology reports 14.7 °C annual mean temperature, 74.1% relative humidity and 1.96 mm/day corrected precipitation. The monthly maximum peaks at 41.9 °C in January.

### Can the Point Cook climatology replace project design temperatures or an hourly weather file?

No. The Point Cook response is gridded monthly climatology; its lowest monthly minimum of 1.0 °C in August is not a code percentile or observed site extreme. Verify elevation, local exposure, the required weather file or design-condition source and the current adopted code.
