The Dubai column is Dubai's mean daily high, for comparison.

Modelled averages for an area about 50 km across, not a weather station's record: NASA POWER climatology, 2001–2020. These data were obtained from the NASA Langley Research Center (LaRC) POWER Project funded through the NASA Earth Science/Applied Science Program.

The model's grid cell sits about 1,088 m higher than the town, so real temperatures there run a little warmer than these.
