Climate Design Data: Dayrah, UAE

Direct answer

NASA POWER's 2001–2020 climatology at the Dayrah reference point reports an annual mean 2 m temperature of 27.7 °C and relative humidity of 69.2%. The highest monthly maximum is 39.2 °C in August, while the lowest monthly minimum is 13.5 °C in February; 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 0.30 mm/day and annual 10 m wind speed is 3.94 m/s. For climate design data, use the 39.2 °C and 13.5 °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 Dayrah?

Dayrah is represented here at approximately 25.2714, 55.3021 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 Dayrah site remain authoritative.
