Recent National Weather Service forecasts for San Francisco International Airport project daytime highs of 68–72°F on May 18 under predominantly sunny skies and light west-southwest winds, establishing strong trader consensus behind the 68°F-or-higher outcome. These projections align with typical May climatology, where average highs hover near 66–68°F amid seasonal high pressure and reduced marine-layer influence. Model runs show minimal disagreement, with consistent warming from clear conditions and modest offshore flow expected to sustain afternoon temperatures. A thicker marine layer or stronger onshore breeze could cap readings in the mid-60s, though such shifts appear unlikely given current atmospheric patterns. Updated NHC guidance and local observations will refine these trends ahead of market resolution.
