During the winter, the city is covered with a thick fog very wet, which in general stagnates all the day. In July and August the weather is colder and warmer clothing is recommended. Climatically, it is a desert of remarkable aridity associated with cold ocean waters along the shore. Air moving landward becomes chilled over these waters. Onshore, a relatively cool and heavy layer of surface air underlies warmer air. For this reason, the turbulence needed to generate precipitation is absent, although the
