it always seems incongruous for deserts to hug oceans and it usually occurs due to the following though baja w a warm current offshore to san diego and N of 30* does not fit any model i'm aware of-would have to look further

Hadley cells located on the Earth's atmospheric circulation.
Heating of the earth near the equator leads to large amounts of upward motion and convection along the monsoon trough or Intertropical convergence zone. The upper-level divergence over the near-equatorial trough leads to air rising and moving away from the equator aloft. As the air moves towards the Mid-Latitudes, it cools and sinks, which leads to subsidence near the 30th parallel of both hemispheres. This circulation is known as the Hadley cell and leads to the formation of the subtropical ridge.[9] Many of the world's deserts are caused by these climatological high-pressure areas,[10] located within the subtropics. This regime is known as an arid subtropical climate, which is generally located in areas adjacent to powerful cold ocean currents. Examples of this climate, the coastal areas of southern Africa (Namibia, South Africa), south of the Canary Islands and the coasts of Peru and Chile.[11]
