The official minimum temperature at San Francisco International Airport on August 21 reached exactly 58°F shortly after dawn, matching the 1991–2020 normal of 57°F and recent preceding days. Marine-layer stratus and moderate westerly flow suppressed overnight radiative cooling while preventing significant warming, producing a low squarely in the 58–59°F bin now carrying 85.5% implied probability. Earlier uncertainty around 56–57°F (47%) reflected model spread and station-to-station differences before the final NWS observation locked in the value. Historical analogs for the date show lows rarely dip below 52°F without stronger offshore flow, keeping lower buckets near zero.
