Regional context

San Diego swings from 55°F in January to 73°F in July (18°F) per NOAA NCEI 1991-2020 normals; precipitation in San Diego runs about 11 inches on roughly 94 measurable days.

San Diego's moisture rides winter storm tracks: February brings 2.1 inches over 9.6 wet days, while July sees only 0.1 inches across 3.0 days in the dry warm season. That groups San Diego with places like La Mesa, CA, Santee, CA and Lemon Grove, CA on the same cool-season storm track.
