Trader sentiment clusters tightly around the 76–79°F brackets because persistent marine layer stratus and strong onshore flow from the Pacific are expected to moderate peak heating at the coastal observation site on July 22. Despite a National Weather Service heat advisory and forecast highs of 85–90°F farther inland, the cool, moist boundary layer typically suppresses afternoon temperatures near the ocean to the mid-to-upper 70s. Minor differences between the leading bins hinge on exact marine-layer depth, cloud-clearing timing, and any subtle shifts in the pressure gradient. National Weather Service model updates and afternoon observations will determine whether slightly stronger offshore flow pushes readings into the lower 80s or keeps them capped near 77°F.
