Solar & Daylight Data
Sun Path: Abu Dhabi, UAE
How to research sun path for a specific site in Abu Dhabi — 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 AE dump](https://download.geonames.org/export/dump/AE.zip) (CC BY 4.0, snapshot 2026-08-31, GeoNames ID 292968). Regulatory starting point: [UAE Government overview of local building authorities](https://u.ae/en/information-and-services/justice-safety-and-the-law/building-safety). Figures are illustrative — verify against the current locally adopted edition for the site. Solar-method context: [NOAA Solar Calculation Details](https://gml.noaa.gov/grad/solcalc/calcdetails.html); the Harth monthly table uses a simpler declination and geometric-daylight approximation whose stated limitations must be retained.
Direct answer
For Abu Dhabi at 24.4512, 54.3970, the declination-only solar-noon altitude is approximately 89.0° at the June solstice, 65.5° at an equinox and 42.1° at the December solstice. Refine these geometry checks with the project date, civil time, facade azimuth, terrain and local horizon. The reproducible location record is GeoNames ID 292968 in administrative area 01, at 24.4512, 54.3970; replace it with the surveyed parcel point before relying on the result. As a transparent geometry check, declination-only solar-noon altitude is about 89.0° at the June solstice, 65.5° at an equinox and 42.1° at the December solstice. Representative 21st-day geometry ranges from about 10.5 hours in December to 13.5 hours in June; this excludes atmospheric refraction, terrain and obstruction effects. The cited national authority is a discovery starting point; current local documents and a named qualified reviewer control project use of this sun path record.

What must be verified for Abu Dhabi?
Abu Dhabi is represented here at approximately 24.4512, 54.3970 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 sun path be established?
- Fix the surveyed site and local time basis.
- Select an authoritative weather source or a named solar-position algorithm.
- Record period, percentile or scenario and units.
- Test sensitivity to elevation, exposure, urban form and horizon.
- 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 sun-path-workflow page is a project-starting worksheet, not a design value or approval. The controlling authority and qualified professionals for the Abu Dhabi site remain authoritative.

Harth computed the Abu Dhabi fingerprint for latitude 24.4512° with the Cooper declination approximation, 90° - |latitude - declination| at solar noon, centre-to-centre sunrise hour angle and 1 / tan(altitude) shadow ratio. Longitude 54.3970° is retained for a later civil-time conversion; this screen does not perform that conversion. See NOAA's solar calculation details. Atmospheric refraction, terrain, facade azimuth and obstructions remain outside this first-pass comparison.
