Current National Weather Service guidance for San Francisco International Airport projects a daytime high near 66–68°F on May 17 amid a strengthening marine layer and persistent onshore westerly flow that promotes coastal stratus and limits afternoon mixing. This pattern aligns with typical May climatology, where frequent low clouds and Pacific advection cap warming below the long-term average high of 67°F, positioning the 68°F-or-higher outcome as the market leader at 57% implied probability while the 66–67°F bin holds 29%. Traders are watching for any late-day erosion of the stratus deck or shifts in boundary-layer moisture that could briefly allow readings into the upper 60s, with final resolution dependent on official station data at KSFO.
