If a large area does not attract moisture, does the moisture go somewhere else?
https://en.wikipedia.org/wiki/Paso_Robles_Municipal_Airport
The Paso Robles Municipal Airport covers about 5.4 km^2 or roughly (2.32 km)^2, and it has large areas of continuously exposed asphalt.

California has a total area of about 423,970 km2 km^2, so there are roughly (423,970/5.4) = 78513 areas of California of that size. If you monitor at an airport, the temperatures are likely to be higher on average, than at a nearby forested or water covered area of the same size.
Copernicus shows global surface air temperature variations in video maps like https://climate.copernicus.eu/sites/default/files/2024-08/t2m_video_to_July_2024.mp4 and generally green means cooler, and bare ground and rock means hotter. And asphalt is often dark colored and hot.
The National Weather Service does record some data for Paso Robles Municipal Airport at https://forecast.weather.gov/data/obhistory/metric/KPRB.html. I see for 6 Oct 2024 air temperatures of 40.6 C (105.08) but most of the time it is less. Every day the sky has been CLR with no precipitation. With visibility about 16 Kilometers (10 miles). They show readings every hour.
For the three days they show (no download, no archive listed, no data options at all) the average of the hourly temperatures is 25.8194 C and the standard deviation is 8.9456 C. So a maximum temperature of 40.6 C is (40.6 – 25.8194)/8.9456 = 1.65 standard deviations.
Now do hot areas attract heat? If you live in or near a place with lots of asphalt, no trees, no water, with nothing to slow the wind? What happens most of the time?
Areas store variable amounts of energy, one expects varying temperature pressure wind and moisture
