National Weather Service forecasts project an 80°F high for San Francisco on May 18 amid a warming pattern driven by clear skies and reduced marine layer influence, supporting the 92.3% market-implied probability for 68°F or higher. Recent model runs from NOAA show consistent offshore flow and upper-level ridging that has already lifted daytime maxima from the mid-60s earlier in the week, aligning with climatological trends for mid-May when southerly winds can suppress coastal cooling. The dominant consensus reflects trader confidence in these verified guidance products, though late-day marine stratus or a faster-than-expected frontal passage could trim the peak by several degrees before official observations at San Francisco International Airport finalize the outcome.
