This is not something I have data on but just noticed from experience. The inland/leeward sides of L.A. hills (away from coastal wind direction) often have ‘hot pockets’ on sunny days, and that affects weather reporting;
e.g. Woodland Hills at Pierce College (North side of Santa Monica Mountains),
San Pedro & Wilmington downslope (East) of Palos Verdes hill,
downtown L.A./USC (L.A.’s main NWS weather reporting center) which is just East of Baldwin Hills/Ladera Heights so usually has ‘Calm’ wind readings,
and even just inland (North/NE) of Signal Hill in Long Beach.

They are blocked from the wind, so get warmer. The elevation differences are not great enough for much adiabatic warming, but urban heat surfaces do absorb and re-radiate.
