Climate Design Data: Soshanguve, South Africa

How to research climate design data for a specific site in Soshanguve — the controlling authority, source documents, and checks to run before you rely on a number.

Last updated August 31, 2026 · Location data from the [GeoNames ZA dump](https://download.geonames.org/export/dump/ZA.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 954013). Regulatory starting point: [South African Bureau of Standards and the local authority](https://www.sabs.co.za/). Figures are illustrative — verify against the current locally adopted edition for the site.

Direct answer

NASA POWER's 2001–2020 climatology at the Soshanguve reference point reports an annual mean 2 m temperature of 19.8 °C and relative humidity of 50.6%. The highest monthly maximum is 40.7 °C in January, while the lowest monthly minimum is -2.6 °C in June; 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 1.56 mm/day and annual 10 m wind speed is 3.13 m/s. For climate design data, use the 40.7 °C and -2.6 °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 Soshanguve?

Soshanguve is represented here at approximately -25.4729, 28.0992 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.

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 Soshanguve site remain authoritative.

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 Soshanguve?

For the Soshanguve reference point, the 2001–2020 NASA POWER climatology reports 19.8 °C annual mean temperature, 50.6% relative humidity and 1.56 mm/day corrected precipitation. The monthly maximum peaks at 40.7 °C in January.

Can the Soshanguve climatology replace project design temperatures or an hourly weather file?

No. The Soshanguve response is gridded monthly climatology; its lowest monthly minimum of -2.6 °C in June 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.
