Current meteorological forecasts and seasonal climatology strongly support trader consensus that San Francisco's high on May 24 will reach or exceed 64°F. Late-May averages hover near 67°F, with National Weather Service guidance projecting daytime peaks of 60–68°F under typical marine layer conditions and moderate onshore flow. Model consensus shows limited cooling potential, as no significant cold advection or persistent fog is anticipated. While extreme anomalies such as an unusually strong marine intrusion or rapid pressure shift could theoretically suppress readings below the threshold, historical data and real-time observations indicate such outcomes remain highly improbable on this date. Official station measurements will resolve the market.
